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.

Man i have a shaky idle on my 18 silverado 5.3 and i know i had a air leak from the valve cover hose that goes to the air intake dealer broke the connector and tried to epoxy fix it but it gave it. Not 100% sure if its the cause of the rough idle i had a new throttle body installed under warranty. I had a bmw and it would misfire from a vacuum leak so i assumed its the same

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).

@Keyno772 жыл бұрын
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.

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.

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.

The correct idle for this vehicle is 500 rpm in gear and 600 rpm in park or neutral.

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

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 😬😬😬
@texasprepper26237 жыл бұрын
Make sure your vehicle is throwing any codes 1st off, as far as the cables wires, plugs and throttle body that's all visual inspection. Rough idle is could be cause by several things as small as small vacume leak and as big as a large evap leak, like a he in the gas tank.
