Thank you TexasPrepper for tip. 2007 Cadillac Escalade Ext was idling once upon a time, until i watched your vid and now it has stopped idling on crank up. I used 93 Chevron Octane with Techron. ^5

Bro!!! Just wanted to say thanks for making this video! I had a rough idle going on in my 2004 Yukon, and the check engine light was on and flashing. I watched your video, went to Chevron, put $20 worth of 93 gas, and all is back to normal!

Rough idle can be multiple different causes on these newer chevy engines. 4.8,5.3,6.0. I did alot of research on these engines. There prone for intake gasket failure. I had rough idle as well. I changed intake gasket.. wala. All fixed.

ok so you should name this video "my tahoe runs good!"

Thanks I have 2005 Chevy Tahoe LT with 240 thousand miles runs like a champ just replaced my knock sensors, spark plugs, 1 engine coil and connectors cleared the code ride about 100 miles no codes yet but has small vibration I checked my wires hoses and vacuum leaks nothing is wrong with it I am afraid to drive it seems like it's going to stall out I use premium fuel and used fuel injector cleaners so my next fill up I'm use Chevron with Techron.

Yes, sometimes, you need to stabilize the gasoline specially when you use cheap gas . Chevron gas with techron and a vp 7 in 1 fuel treatment help my 2005 silverado rough idle.

Should be idling around 550-600 RPM. If you fall too far below 500 you'll probably start getting misfire codes (I know when one of my spark plugs got fouled it was varying between 400-600 RPM and got codes).

I have made everything, im so happy this really works for me!!!! I love techron

Had multiple missfire code on a 05 Silverado and all I did to fix was use seafoam in fuel. I didn't think it would work but it fixed the problem.

These trucks idle rough because they burn oil. Carbon deposits create preignition detonation knocking which can be heard on heavily under acceleration. The real fix is to get the updated left valve cover and the updated tiny oil splash guard that goes on the oil return nipple inside the oil pan, and a professional seafoam or system clean to prevent hydro locking. Higher octane fuel is less prone to cause knocking with carbon deposits and compression and the additive helps clean the system in the very long term. Is like engineers want our engines to break with this PCV systems, thats why oil catch cans help reduce this by reducing oil contamination in combustion chambers.

New plugs and wires helped mine. I'll also go give this a shot to.

Same problem with my 07 truck is like brand new well under a 100k I just threw money and Parts at that thing and I just gave up it is what it is that's what the truck does. All these 5.3 's do the same exact thing.

This video was very helpful for my 2010 Tahoe thanks man. Going to try better gas and some fuel intake cleaner.

Thanks, I'll try this. I have been using reg gas, and have been using the gumout with P.E.A.. With only 67k miles its rough idle but runs smooth. Have been noticing a surge sometime also.

These year Silverado and GMC LS engines wiring harnesses are piss poor! The loom is very brittle if youve noticed?

Yeah I did spark plugs fuel pump new canister new charcoal canister new spark plugs coils and wires new brake switch but it still shakes a little at idle the only thing I have not done so far is throttle body and MAF sensor I have not change that yet maybe I'll spray some cleaner in there until I buy MAF and clean throttle body out but yeah I'm still getting a little ruff idle but if I reve it up it's fine it's only at idle it's like up and down a little trying to figure it out I just put a new fuel pump in it too

Thanks for the video. Did this issue just come on suddenly with you? That just happened with me and I've had the Tahoe over 3 years. Thanks.

I have the same issue. 08' silverado LTZ, 76k miles, I have changed plugs,wires,cleaned the intake, installed bully dog, and K&N intake installed. Still shudders at idle!! It's more annoying than anything! Always wondering if it's going to stall... you should actually do a video of listening to the exhaust. That's where I hear and feel it. Any new tips on how to solve this are welcome!! Thanks.

I cleaned my tahoe 2012 throttle and the RPM goes to 4 ! , I switched the car off and did the following. First, I disconnect the negative side of the battery. Then, I start the car with the key to the maximum for 1 sec and switch it off, then I repeat last step again, then I start the car gain with the key to the maximum for 15 sec and switch it off. Then, I reconnect the negative side of the battery again. then, start the car as normal and left it running for 3 minutes. then switch it off, then start it again for 3 minutes, then switch it off for 5 minutes. then start it as normal and start to drive. It works for me and I hope it works for you as well.

mine I had to replace the plugs and 1 coil because it originally had an e85 motor...that motor died and was replaced with a 5.3 long block. the guy did alot of shortcuts....installing the old used misgaped plugs and after I got all new properly gaped plugs and replaced the throttle body and coil..it still has a rough idle. only when i take off at 20-25 the light goes off...I'll try your trick with the 93..my 81 jeep ran like a caddy when I used BP 93

Get a catch can. Gm mostors recirculate oilly air into the air intake, thats why we need techron. To fix run 4 cans back to back of techron, put on the catch can, and 3rd is if ypu want the idle smooth asap, go get an injector cleaning device. They are only $60. You pull each enjector you put the wire from the machine onto the injector as you spray carb cleaner through it. The machine fires the injector and if its fouled you see it with your own eyes go from a splatter to a nice fine mist. Then put it back in and done. Do this for all 8 injectors. Look up how to remove injectors first. Some cars it tKe 5 seconds to get them out but other cars take forever as the are buried.

oil pressure seems low. I have an lq4 and an ls1 and they both run just over 40 at hot idle. ls1 was running low like yours maybe a bit lower and I dropped the pan and saw the pickup tube screen was pretty clogged. cleaned it out put it back in and it runs over 40lbs again. something to think about, low pressure will cause that lifter noise as well. hope the cars still treating you good these engines are more durable than they get credit for.

Oxígeno sensor change it I’ll do it no codes but the truck running smooth now !!!!

I'll definitely give it a try. When is the best time to change your plugs....I have 124,344 miles.

Could be a map sensor issue… Techron isn’t a quick fix to a real problem.

Same here but had to change value n exhaust on engine n pvc too … gonna try the chevron Techron n let u guys know what happens

I removed my k&n intake and my ran smooth again and gain power back

Do both your hi and lo cooling fans run at the same time when the engine is running?

It can be a coil pack for sure

Mines doing the same exact thing runs great but a weird idle dont no why im a scared too it might die at a stop but no check engine light nothing like that I'm thinking about trying better gas I always use 87 but I'll try 93 if it helps or not and it's also a 5.3l flex fuel too

Yeah i put gas at a cheap gas station after that my truck started to splutter went back to the usal gas station and the problem has gotten a bit better

What about the techron fuel addative?

If it is running rough, has no power, misfires, straight up running like crap then change your crankshaft position sensor. It’s behind starter.

Don’t know if this will help anyone but I got a 07 Yukon 5.3 that idled rough and felt like it was jerking. Replace the TPS and it went away

Great Idea... I am having the same issue... Just filled up.. .Going to try that next time.

the tick is normal as long as it's not clacking like a diesel

Flex fuel works better with E85 or 87 Mine runs best on 87 418 miles on full tank

Dont hurt to have the injectors from the fuel rail cleaned. My one tahoe 2011 have a bad coil, used old school timing light dead coil. My Escalade has bad idle , coils all good but suspect dirty injectors..n

Talk about throwing money away. You are doing exactly that running 93 in an engine designed for 87.....

i let my mom use my 04 Tahoe for about 6 months, when i gave it to her it only had 2 minor scratches on it, and ran like a new vehicle. after she finally decided on a car to buy, I went to pick up my tahoe. anyways, she put gas in an old metal gas can which had water and rust inside of it. My mom said she just filled the can and poured about half of it inside the tank. so I went to pour the other half of the 5 gal. tank inside and seen it was brown and quickly stopped, Yes i was upset about this. then my brother stopped by and told me that there was like a half gal. of water inside of there from being left out in the winter and half the summer. So i threw a few bottles of Heat in the tank and had my brother take me to get a new gas can and gas. there is a mechanic that works at the gas station which has a shop attached to it, and he told me to put in 93 and let it run until there was barely any gas in it. well now i am getting sputtering at takeoff, and when i am driving it at 25 to 55 mph after the engine warms up, then at stops it will die out on me or sometimes at low speeds it will die out. when i hit the pedal hard it doesn't do it or it will stops sputtering and dying out on me. I am thinking I have clogged injectors, or a blockage in the fuel line somewhere. I changed the pump, so now i guess i'll be changing the fuel lines and injectors, and possible the intake manifold and carburetor, then cleaning out the inside a little. any advice would be appreciated and considered.

So you think it's bad gas related? My girl was using my truck and stopped at the closest gas station (real cheap gas) I always put chevron and after that cheap gas it started acting up you think that got anything to do with it?

Mass air flow or IAT

Thanks ,super informative.

What’s another good gas there is no chevron around me

If that helped try running E85 ethanol your truck runs on it I run half Chevron with techron and half E85 ethanol

Did you run it without oil or water?

I got an 07 Tahoe my stabiltrak & traction control keeps going on and off on and off and it'll even make my truck die out it's been giving me hella problems I've thrown money at it for all of 2020 idk what to do .-.

when you clean throttle body you have to relearn your idle. i having random misfires in my 6.0L i need to do a crank sensor relearn

I had the Same problem . you need to clean the throttle body

Great video. What plug wires are you using?

What map sensor set up do you have mine is mounted on the side

My neighbors 09 Tahoe that I'm trying to help him fix started running itself up and holding rpms after letting off the throttle, after I cleaned his throttle body. It drives like it has cruise control automatically set to whatever you last had your foot at when you let off the pedal

Just changed my spark plug and wires now it’s running rough and check engine light is on I checked the gapping on each one but it still runs rough any solutions?

I've never run anything but Chevron with techron and it still idles rough.

Install an oil catch can then give it a major tune-up

Question my 07 tahoe 5.3 is not overheating but tge gauge reads slightly over half way on the dash , what could it be

Where do you get that 140 mph speedo…….

I read that rough idle is normal on these because it is programmed to idle lower than usual

About to get rid of my 07 Tahoe. To many problems. Starting to get really expensive. Never thought I'd say this but I'm getting a Toyota.

Can I use that stuff with my flexfuel

I have an 08. I am getting misfire and random misfires in cylinder #4. I put in a new spark plug, new wires. I swapped the #4 and #6 coil and still got the #4 cylinder misfire. I’ll get the check traction control and stabletrac on idle. But after I give it gas it will clear. Could this be a bad fuel injector?

Acdelco fuelpump problem solved

clean the idle air control valve since the idle looks a little lower than normal,chrisfixs last video shows you how to do that

I luv this truck

What us chevron with tech Ron

I haven't seen chevron in North Carolina so what is the other option ?

Eating oil?

bp or chevron if not my truck runs vad

my 08 Tahoe started acting up yesterday, I smelled burnt plastic, nd then the transmission light came on, now it shakes when running, any ideas??

Just got a can, going to add it to my 08 tahoe with 140k miles. I know a lifter colapsed.

Is this the 6.2?

Chevron with Techron. I think Texaco also adds Techron to there fuel.

I don't have Chevron stations near me. Will the additive work, too?? Been running 93 octane for a while to help with oil consumption on our '08 Avalanche. Only idles rough, goes away at higher rpm...

Mine idles after I pump gas

So wot was the main cause of the rough idle?!! I am facing the same problem we tha car stands still RPM hasetating 😬😬😬.. Did everything you hve mentioned plugs +cables+coils+throttle cleaning+ fuel cleaning 😬😬😬

what was the gas you mentioned? wanna try it

I have a 2008 chevy 5.3L V8 LTZ Tahoe which idles rough around 500 rpm. Getting a P0307 code checked all wires, plugs. Also seeing a little white/greyish smoke when idling sometimes. Need help

that Drake in the background made this video great😂

i use. 711 no problem. with. my car

This must be the worst form of proof ever, i work delivering fuel, arco and movil and chevron is the same fuel lmfao ur off buddy

Any clue please let me no thanks

I have a Chevy avalanche with the same nasty idling and switched back to 93 and my problem was fixed just like that so I back you up

It sure couldn't hurt for you to clean the engine bay and components. It will definitely help diagnosing certain issues.

Your oil pressure is low

How much your MSD spark plug wires cost ?

I have a 08 Tahoe isle good but drive bad change coil and plug and wires still engine light on and saying same thing

So that’s alll u did was switch gas

Silverado or 4.8 -6.0 are drama queens lol

MAF

The only real fix for these gm motors is to find a brilliant technician or replace everything.

That air intake is dirty asf

oil pressure is suppose to be at 40.

That don’t work

Peace up... thanks bro! Phuck H8erz

Didnt help

Chevron sucks and cheap has with water mix

👀👁🔴

G

You talk too much

To many ahhh and uhms Wow!!!
