I get a lot of questions via email and over at the forum about the steps to take when you encounter a performance issue like my Subaru's hesitation issue and I often feel like I sound like a broken record when I cover the basic steps that I cover when encountering a situation like that. My main point here is that if you have a performance problem and you're going to throw parts at the problem start with the basics before you to off and start replacing sensors that you suspect are a problem, if you don't have evidence of a faulty sensor then don't start there start with the simple tune up items and check for vacuum leaks and air leaks as I've shown here and I believe you'll have better results and save yourself some money in the process. In short the rule of KISS applies, Keep It Simple Stupid.
If you have questions about your own engine performance issues head over to my website and either ask the search function or ask the forum, we'd be happy to help.

My 2000 F 150 was running bad, really bad. Chugging, stalling, jerking, I mean bad. It hadn't been maintained at all. Watching your videos inspired me to try a couple of things myself. I changed plugs and plug wires and installed a new fuel filter. These three things have more than doubled my fuel economy and overall performance is great. I'm a believer in maintenance now, a changed man and I owe it all to you and these great, easy to understand and informative videos. Keep up the good work.

Hey Eric, Tanner here. I know you probably have 2500 other comments like this, but you sure know how to make a helpful video. I used, in particular, the spark plug section to help me with changing the spark plugs in my '95 Range Rover 4.0se. Now, I'm not a total idiot with cars but that doesn't mean I'm particularly mechanically inclined. Your channel has given me some solid confidence to tackle my vehicles mechanical needs. Anyways, back to the point. I switched out my spark plugs today and man, I sure can tell that my car is happier. A little surprise i found is that the starting of my car seems to have improved noticeably, which I was happy to see. The performance of the car itself also seems to have been improved. I suppose that's what happens when you get rid of 20 year old plugs, eh? Needless to say, I'm a happy guy! Anyway, thanks for the videos and for the confidence to pop my hood. Tomorrow I plan to flush my power steering fluid. Wish me luck!

Thanks for good tips Eric! I have a 1996 Mazda 323 (I believe it's called Mazda Protege there in the States). 1,5 liter 16 valve DOHC engine. I had some idle issues with it and significant decrease in power lately. Now I replaced the old fuel filter and cleaned the MAF- sensor. While taking the air intake housing off to get access to the fuel filter I found out that the housing had huge cracks in it, so unmeasured air was getting into the mix. Fixed it and now it runs smoothly.

One tip for installing spark plugs is to gently lower them with your socket wrench (or torque wrench and socket) and set the plug on the threads until its just about to catch but don't tighten it yet just turn the plug counter clockwise very slowly (like loosening it) and wait till you hear or feel a tiny "tink" and that's the very top of the thread of the spark plug dropping in line with the very top of the head's thread for the spark plug. Once you hear that tiny "tink" start tightening it to torque spec and you'll never cross up or bugger the threads since pretty much seems like most if not all heads on cars these days are aluminum. (not sure if I have ever seen any car without aluminum heads)

I do the same except I do not bother turning them left. I start tightening by hand right away but just use my fingertips so no real force is applied. Then spin them til snug and that is when the socket wrench comes into play for final tightening. Crush down the crush washer until snug and then maybe a 1/4 or 1/8 turn to be tight.

Eric, Autolites don't belong in Fords any more than they belong in a Subaru. Fords have run Motorcraft since the 70s, when they sold Autolite to Allied Signal. Autolite is an aftermarket plug that has many specifications over many different car manufacturers. They're not OEM on anything I'm aware of. But I agree, NGK would have been a better plug than an Autolite.

i noticed something about the spark plugs that you missed, they are blowing the compression pressure through the spark plug. you can tell by the brown witness marks going up the ceramic part of the plug after the metal part of the spark plug.

@kenmadritsch8419 7 жыл бұрын

XC if your spark plugs are platinum or iridium and the threads are coated in a silver finish then there is no need to use anti-seize as they are already coated in a property that restricts them from being a pain in the ass the next time you take them out! lol

@Nikkuuu69 7 жыл бұрын

NGK plugs don't need anti-seize, they state this on their website, and the plugs are pre-gapped most of the time. You can check this with a feeler gauge.

@xc8487 7 жыл бұрын

Nick Leijenhorst Even if they are "pre-gapped", you should always check anyway. Also every engine requires a different gap, so the gap set by NGK may not be correct. Anti-seize is very important for aluminum heads to prevent thread galling and reduces the chance that you'll break the plugs during removal.

@dhalsim-1 6 жыл бұрын

XC NGK don't require anti-seize or gapping. Just make sure you get the correct spark plug no. for your car and they'll be fine.

Love the videos! I would disagree with you about gapping the spark plugs. (Remember I'm the guy with 3 engineering degrees, certified in engine, transmissions, and tune up by the time I was 16 and won the Pacific automobile award when I was 17. So I'm a real nerd. But I can always learn, and your videos are terrific.) The size of the gap is critical as it determines the energy released which is very critical. The reason that you may not like the autolight's is that each spark plug has a specific resistance which determines the current flow and therefore affects the energy released. This resistance combined with a spark app the spark app determines the total energy released. If you had issues with autolight's, you might try increasing the gap a little more than the specification which will deliver more energy. Spark plugs are actually very simple devices. However when I was researching this for my tuneup certification, I did note that the resistance varied amongst the different manufacturers. This is easily addressed by modifying the gap to make the total energy release per spec and increase performance.

I have a 95 Buick Regal Limited 3.8L V6 multi port fuel injection. I have had the same issues the car doesn't hesitate when you first drive it and it's cold, but it runs alot better in cold weather. I would drive it at about 45 mph and up, then it would hesitate under acceleration. I first thought it might be the fuel filter since it's never been changed. lately I have come up with a new theory that my battery is very old and just not able to hold voltage as well anymore, and when it's trying to take the power from the battery to the engine it just can't get enough. I am going to pull my spark plugs and see if they are to the right spec. thank you for this video, you reminded me of myself. ☺😧

I would've (liked to see you do) hacksaw the filter open- check for water, rust, corrosion, bits of rubber lines, etc. that may be coming from a line or tank. Usually the in-tank type pump have a strainer to prevent that- but I've seen those rot through, and come loose enough to let debris through- even the guts of a pump can disintegrate.

Hey Eric! What spark plugs would you recommend for LPG modified car. Car starts on gasoline and runs for some time until engine temperature goes high enough to change to LPG system. So car runs on LPG 90 % of time. LPG burning produces higher temperatures and has higher octane number so spark plug producers recommend different spark plugs, made for LPG. Ones that can resist higher temp and with smaller gap for the better ignition of LPG. Aparently LPG ignition calls for higher voltage so other parts of the car can suffer if the gap is not small enough. On the other hand some mechanics still go with the factory recommendation for spark plugs. But if you put LPG in, its not a factory set up anymore. So what is the best: 1. Original factory recomended, 2. Factory recommended with making the gap smaller, 3. Saprk plugs made for LPG, like NGK LPG2 (for my car Chevy Aveo 2007, 1.2, 53 kW, euro version) which has already smaller gap and better materials for high resistance to temp and much more expensive?

I am having perhaps a similar issue in 2007 Forester. I have no check engine light and historically the car sat for a year or 2 with dirty tank and blocked in tank filter as well as failed in tank strainers. I first changed filter, Strainer and put aftermarket pump, then I used POR15 tank process with second new filter and left side strainer, then new genuine fuel pump module (filter, strainer, pressure regulator, gauge and pump). Along the way I have cleaned injectors twice, new genuine plugs early in the game, air filter and throttle body cleaned several times. I am now leaning to dampers x 2 on fuel rails (they might be a mess based on original tank condition), Electronic throttle pedal (a friend had one that needed cleaning once) or wondering if the Cat has an intermittent blockage (can that happen?). There are times when the car runs very nice and than pretty much out of the blue performance reduces to about half. It never leaves me stranded and even gets up steep hills just relatively slow. If I floor it it does kick down and rev high but on upshift it looses power again. Before I resealed the airbox in the fender that box used to buzz a lot under power loss conditions. Any ideas?

when the pressure rose when you shut off the engine is know as the water hammer effect From Wikipedia "Water hammer (or, more generally, fluid hammer) is a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). A water hammer commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe. It is also called hydraulic shock." correct me if I'm wrong.

Eric, a question for you. After recently buying a car with a 12 year old car with a full service history, last being 400 miles prior to purchase. But it's been sitting months. So I put fresh molbil1 (as suggested), oil filter new and correctly gapped and torqued spark plugs and a pair of k&n panel filters. 1000 miles later it seems to be lumpy on cold starts and the mpg's seem poor. Old plugs that came out were in good clean condition without oil or water on them. Cleaned both MAF too! Any suggestions would be appreciated.

iVlog intake leaks can reck havok on some cars, even the smallest of leaks can make some cars run like garbage. PCV valve might cause this is some cars, quick $5 fix. EGR valve might also be causing your issue but it is better to cover the simple issues first as they can be the cause of more complex issues.

I have an esue with my s60 volvo 2001 non turbo. It jerking when i put into higher gear especially when it cold start. The spark plug was change 2 years ago, i had replace 2 of the ignition coil lately, this problem came when the mass air flow sensor had an esue I cleand it but still have the problem. The problem is no engine light no code so I don't know where to fix. Maybe some oil got into the spark plug when the vvt gasket broke and oil runs around the ignition and into the timing belt. The motor run smothly when it idleing and the rpm is normal. I know that there is no esue with the transmition gear. I don't know maybe I will let the pro look at it. Any help out there?

How funny for me to happen across this video. I have a 96 legacy outback and have a similar problem. I've resorted to manually shifting through the gears (1,2,3,D) and have seemed to eliminate the problem doing that (and having more fun driving). But It still struggles on hills, I have to take most hills in 2nd gear or else my engine gets mad at me. Light hills it can handle 3rd gear but only if I keep momentum and the revs higher than like 2800-3000.

Any car that is boosted (Forced Air Induction) needs NGK plugs. Im a technician for a living, and I specialize in air induction, and performance cars. Also, it needs 91+ octane. Anything less is not sufficient. But, ETCG1 your amazing, when ever I'm questioning my self, I look at your video's to get clarification and tips. THANK YOU!

It's important to mention that factory plugs and wires usually have different resistance to what you'll get with AM plugs/wires. Always at least call the dealership for pricing too, because I've found some parts are actually cheaper at the dealership (eg. thermostat in '04 Liberty in my experience).

hi a great video, I will tell you my experiences with spark plugs. I have a Peugeot 206 1.1 L, I know a little engine lol lol . I kept getting a misfire and a engine management light come up and the engine would seem to stall for about a second ending the engine management light would come up, it would do that every 20 miles down the motorway, anyway. Eventually I changed the plugs . I had the spark plugs you put in your car. The new ones, and on my Peugeot, I had to use champions spark plugs and the misfire went away instantly. I've used them spark plugs for a year now. Never had that problem again , excellent video

air filters , dirty throttle body , clogged catalyst , restricted injectors , bad MAF sensors has the biggest hand in your current issue beside what have you mentioned , but mostly new cars now comes without fuelfilters because it usually placed aside to fuel pump inside fuel tank , i usually run a scan ( when no check engine light ) and pull all engine data live and compare o2sesnors amps , short, long fuel term , maf voltage , spark advanced , injector timing will make u understand !

i owned a honda accord sedan from 1986 that we put bosch sparkplugs in, and it didnt idle great, poor performance, and then i put NGK in it and it was great. So yes they are actually very important.. And great videos..
