These are the types of videos that KZfaq was created for. Clear, concise facts. Well done.

Really awesome when someone puts time and effort to make these videos so that you gain a knowledge when attempting to DIY on your own car. Keep up the good work.

the last minutes was very important to me as it explains what could cause the problem. Thank you.

Fantastic tutorial, simple and concise and exactly what I need as I have the same issues with the engine jerking. I will be doing this job myself with confidence after this tutorial. Big thumbs up.

Been looking for some new channels to watch recently as my regulars aren't posting as much. Glad I found this great content mate

Thank you for your sound advice. I just investigated the problem with my Corsa and the problem was just the same. Even the same corrosion that caused one plug cap to fall apart.

Thank you so much for your easy to understand explanation on why our Granddaughter's Vx Corsa 1.2 car started playing up this morning!

Fantastic, I have 1.2 version and same thing was happening. Fuel injectors also leaking so thought it was that but came accross this video and you have hit the nail on the head👍🏻

Thanks for the advice-fixed my brothers Corsa following this

Brilliant tutorial, thanks for helping me out! 👍🏻👏🏻

Very useful fella. I changed my daughters 1.4 corsa yesterday. It has transformed it. 2 cylinders were affected by bad corrosion . Excellent call. £106 from euro car parts. 5 minutes to fit, but a year of engine light coming on. Vauxhall should recall for clearly failing to resolve this issue.

Well done Ant..love it hope you and the family are well bud.x

Thanks very much Anton, this is helping. The problem is exactly as you described. I will attend to it right away. It seem to be a very easy DIY.

Thanks man best tutorial on KZfaq think this is exactly what is wrong with mine 😁👍

Super, thanks for this video. Followed the instructions and made the job easy. Thanks again

Very helpful thanks especially releasing the coil connector plug

Great Video, Simple explanation. Great Job

Thanks for this video, I have the 1.2 and the misfire is intermittent but I’ll have the coil pack and plugs changed this week

Sharing his knowledge…brilliant. Thanks

Great video thanks buddy. Saved me a few quid there. Much appreciated.

Thanks excellent video,,I'm still old school always using copper slip and turning it in by hand,, also using water displelent spray on leads,,, keep up your great work,,,👌

Got this exact same problem😒😒 thanks for this man, really going to help.

Had this exact issue with my 2016, many thanks!

Thanks for your video for helping me it fixes my car. found out the coil pack was the problem. It was causing the car to misfire. 1 was very corroded

great advice ...thanks a million !!! really clear and concise #

Great vid thanks for sharing! Need to do this on my nephew’s car today

My coil pack went today in my vauxhall insignia,funny you say about that clicking mine clicked every 15 seconds i wondered what it was,after today watching your video I know what it is 😒 Great video 🙂

Nice video cheers mine exactly the same gonna be sorting mine.

Thanks for the vid. Just doing a service on a 2011 corsa d. It's only done 20k miles but doing the plugs I notice number 4 is covered in white powder substance & corrosion. Pulling the rubber boots off and the other 3 are nice and clean but 4 is totally covered with the ends of the spring completely corroded . Can only assume water is making its way into number 4 cyl only. Have a new coil ordered from AutoVaux for £87 which doesn't seem a bad price for the same Delphi part as the one in the vid.

You knows what I changed my sparks but still had a tapping noise coming from the right tap pit I thinks it’s the sane problem you mentioned I’m going to have to get one and let you know but it all makes sense so thank you for insite brilliant video 🏆

Top man thanks for sharing, just had my car diagnosed by auto Plaza in west London with head gasket needed replaced and few other bits up the exhaust. Paid £1800 and as I got it, I experienced this issue 10 minutes after I drove off from their garage. They were like it shouldn't be any problems at all. Don't know what to think, either being ripped off, unlucky or just being idiot. Wouldn't be surprised if they'll ask again for some enormous amount of money for this issue when I'll drive back in tomorrow

Thanks Anton,i just found my problem here and i will solve it,thanx

Nice one Anton

Thank you top man . 👍👍

Great Video mate. Was wondering how that clip tab came out.

interesting video thanks alot

Big thanks fo helps 🌹👌

Excellent thanks

Found this as my 2011 1.2 16v started jerking, nearly cutting out, clicking, no power, check engine light flicking on/off. Having new plugs and ignition coil tomorrow. Thanks so much.

Great video. Very common in these cars. When you planning to change the water pump on it?

What size socket is it? 16mm?

Thanks pal

Z20LET here and my car loves coil packs. I bought a brand new one only last year for her, already i have eml light and misfire, judder upon boost etc. Vauxhalls love coil packs, dunno why they just do.

Fantastic tutorial.Thank you so much for amazing video.May i ask a question? My Corsa D 1.4 (2013) sometimes jerking,slightly shaking, refusing to accelerate, service light and check engine lightcomes on. The problem only occurs when engine is cold.After a 10 minute drive, it never show up again. Or if i shut down the car, and start it again, the problem goes away too. The mechanic said to me there is no misfire, the fault code said 'acceleretor pedal sensor ' issue. But i am suspecting that my issue somewhat related with ignition/misfire.Is there any possibility that a misfire can cause these semptoms when cold but goes away when engine reaches operating temretures?

Thanks for the nice video! Cleaning the inside where the spark plug and the coil pack contact is not necessary? The grease that you talk about, would this be ceramic grease? Would it also be a good idea to put some on the rubbers of the coil pack? Thanks in advance!

Hi, Thank you for your video. I have the exact same issue with 2007 Vauxhall corsa petrol every 2 weeks spark plugs go bad because water drains into it to the point I had to replace the ignition coil. Do you have a tip what should I do to avoid water drains down to spark plugs? Thank you.

My exact problem. Cheers makes better then going to main dealer.

Great video thanks. I just replaced a v corroded spark plug on my wife's 1.4 meriva (jerky and fault code p0304, new plug seems to have sorted it, coil looked ok, and other 3 plugs all shiny). One plug was also replaced under warranty a few years ago too, along with coil pack so totally agree with the water ingress corrosion issue! Any ideas on how to prevent in the first place?

Howdy. Thank you for the informative video. I have a question. I recently downsizied to a 2019 and it's my first vehicle with start/stop functionality. I'm a little bit worried about that - isn't it bad to have a turbo engine cut off abruptly when stopping? And how reliable are the turbos on the 1.4turbos. Do you replace a lot? Greetings from Johannesburg, South Africa.

6:20 you mentioned two different type of coils now if the GM number is same but the shape of the drums going to plugs are different is there any issue? I have seen a video someone changed and he said it worked

Hi, great video, helped a lot however the orange clip to remove the plug is broken, so you know where I can get a new part or what it is called ?

Morning , you mentioned there are two types of coil pack for the corsa , can you advise which one I need for my daughters Corsa eco flex energy 1.4 2015 ?😊👍

Hi, amazing video! One question, what would a mechanic charge for this service? Assuming all parts are bought by the mechanic. Thanks

Hi, do you get the flashing engine management light with this issue? Mine has Engine management and Traction control lights on and the car is Jerking very bad. Please any advice would be appreciated thanks 🙏

I ordered a coilpack and sparkplugs from bosch The coilpack is not necessary but i think its better to change the coilpack also😊

Hello mate. Hope you have time. What oil do i out in my corsa 2010 plate 1.2 engine please buddy. Don my coil discs and most your videos on my car too. Cheers pal

would you say this was the same with the 1.0T version? i bought one second hand and it doesnt feel like its running anywhere near the way it should. ive been told it could be the Balancer Shaft in the engine and the garage i took it to replaced the coil pack and plugs as far as i know but didnt seem to make a difference.

Great video thank you. My only question is what mm spark plug socket should I be buying? I have a choice of either 16mm or 21mm, does it matter?

Is that A14XER engine ? Did you have issues with PCV valve diaphragm in valve rocker cover ?

What are the recommended gaps on the plugs? Is that determined only by the vehicle manufacturer, or also by the spark plug model? Where should I look for these parameters? Finding the correct spark plugs seems to be pretty cumbersome. When I tried to use the part finder on different sites, like Bosch, I'm told that the entered VIN is invalid, although I checked it 3 times...

The hexagons on the old plugs look rust-free, i don't think it failed due to water infiltrations. Anyway i have a 2003 Z12XE Agila and a few days ago i'd been checking things and letting the A/C pump run for a short while, with the hood open. Heard a distinct click while the engine idled and i'm sure it wasn't the AC clutch or the rad fan relay. 70k miles and the Bosch coil pack has never been replaced (only the plugs, last time has been about 2 years and 3k miles ago, Russian made Bosch FLR8LDCU+ ones). Feels slightly jerky, especially when the engine is warm and under load, but the EML never gets on and there are no pending codes either, and idle looks fairly stable. I've also cleaned the MAF and the throttle body, and replaced the pre-cat O2 sensor, but it still feels jerky. I'll replace the coil pack soon.

Hi have corsa d 1.2 it keeps losing power going up hill so if I am going 70mph it drops to 40mph but when Back on not a Steep gradients works fine what causes this

I have a corsa 1.2 ecoflex when I start it up and try and take off it cuts out but if I give it a bit revs first I can get it going when it’s just sitting ticking over it’s juddering not much knowledge of cars but do you think this could be the problem?

Does there is any kind of joint we can use to avoid water to enter and corrode sparks and coils ?

Anton, We have a 2010 Corsa 1.0 litre engine. Misfires in all gears and only kind of goes away on the motorway. We replaced the spark plugs and the coil pack and this hasn't sorted it. Also did the pedal test and no faults. What can I look to replace next?

Hello mate, got an 09 plate one. It judders on acceleration, but it seems to tick over fine. Reckon it could be the same issue?

When idling my Corsa sounds like it wants to cut out and shales whilst doing so. Had a few suggestions. Do you have any advice?

Does the coilpack misfire trigger any trouble codes? A work colleague has a 2007 1.2 and the engine is jerky when under load. I have a cheap obd2 reader and there were no codes present.

So my car is a corsa d and it starts jerking when I let go of acceleration even a little will this be the same thing do you think ? I have had my car for 3 weeks I’m a new driver

A good video and might just get have solved my sisters ticking noise in her 1.4 Audo SE.... top fella

hard to find these coils down here in my country i need to pack my car for months. we usually have the single coils not the 4 pins

Hey anton 2006 astra h has a miss fire on cylinder 3 rac said coil pack but i got the car cheap an dont fancy spending loads of cash on it so do u have videos of how to test coil pack injectors an so on before i start buying dtuff lol

Had an engine MIL on a 2014 Corsa 1.4 D model. Scanner revealed coil pack issue as did dealer level scan. Replaced coil pack with Bosch (Haas didnt work) coil pack amd changed plugs while coil pack was off and now car runs great..BUT engine MIL light is still on. Have done 1 drive cycle lasting about 20 mins but it hasnt gone off. You didnt say at the end of your vid if rhe MIL went out straight away or if it needs 3 drive cycles. Hoping its nothing else as dealer level scan only showed fault with the original coil pack and now running great with the Bosch replacement. Can you please advise ?

My 16 plate corsa going into limp mode on cold/ damp mornings. Turn the car off for a min then restart then it’s ok. Any idea

Great video. Is there a way to avoid getting water in there? I've changed the Coil Pack twice, getting the same water problem both times. How can I fix this permanently? Thanks for your vid. Cheers

When I goto pull away in my j mk6 it seems to struggle would this be the smae problem as this?

Those heat resistor springs Which way round do they go??? I’ve put the green tip facing down touching the spark plug ????

I have changed the coil pack (HAAS) from euro car parts and all four spark plugs (Bosch) but it’s still misfiring, than engine light came on. Took it to local garage and the diagnostic picked up backbox pressure 🤷‍♂️😅 Anyways, they didn’t manage to solve it and problem still persists. Any ideas on what the problem might be please?

Ever since I replaced my coil pack on same model it stalls out when at running temperature. It will start again after about 20 min. Could it be the 50 quid cheap coil pack instead of a good Delphi or could it be the plug connector pins expanding when getting warm causing bad connection thanks.

Hi have a similar problem on my MK5 Astra, What do you think is a fair price for a decent replacement coil pack?, Thanks.

So Ecotec big booboo not making that cover waterproof. Stick a diy rubber gasket from old inner tube?

my coil set ( opel astra j 2017 ) stuck and it doesnt move , i cant get old coil pack ( not coil boot but whole coil pack ) , can you help me sir ?

Nice video sir same problem with my Corsa d 1.4 2013 I replaced sparkplug at work shop but tomorrow morning I start car Nd same problem engine jarking advice me what can I do now 😔

What’s the model number of the Milwaukee ratchet? Looks a great tool

Is it possible to just clean these springs with cleaning spray for electronic contacts? Today I cleaned one of the springs but I saw thin wire wrapped at the end of the spring most of the wire was gone tho is it a problem?

What size spark plug socket ?

is it best practice to always change the spark plugs

Just got an 1.4 SRI Corsa D yesterday. Only done 32000. I was disappointed when driving it. For an SRI it felt sluggish and juddery. It's fine cruising at speed but its just doesn't feel pokey and judders a lot when taking off. So would a new coil fix it?

I'm having this problem and need to drive long distance. Will I be okay long distance to get home to my mechanic?

what tools do I need to perform the replacement

Will them spark plugs fit into a corsa d 1.2 petrol?

I have a Corsa D 2010 1.4. On idle the revs keep on falling below 500 and then back up to about 700. Repeatedly. Acceleration in the first gear feels sluggish. MPG has dropped. Could this be the coil pack?

I had this problem , my corsa 2017 1.4 sri done 35 000 , £ 220 at Euromaster wasn't sure if fair price (:

I really need help, my corsa 5d 1.4 the kicks in when I on the ignition. What can I do.

Has that corsa a loose timing chain ?

Did any warning lights come on, like the ESC warning light?

Yes the Focus 1.6 MK2 could have the same issue caused by leaky washer jets.

Is water ingress in the plug chamber a common fault with these cars As my partners daughter has a 1.2 corsa With water ingress,will it damage anything

I managed to remove the coil pack but all the rubbers stayed in the head, any idea how to get them out?
