Customer Question

I have a 2004 chevrolet suburban 2500 6.0l that wants to stall when I stop. I can push on the accelerator and it will stay running?
JA: Are you fixing your Suburban yourself? What have you tried so far?
Customer: Yes. It just happened yesterday and thought I would do some research before diving into it. It has 192,000 miles and when i fill it up the gauge reads only 3/4 full and then it's hard to start.
JA: Will the headlights turn on? Is the battery fully charged?
Customer: Yes
JA: Anything else you want the mechanic to know before I connect you?
Customer: I haven't change the fuel filter yet.

One minute while I pull up your vehicle

Expert:  AMEDEE replied 9 months ago.

Sorry for the delay! I lost connection for a bit.

The most common cause of this stalling condition on this vehicle is a dirty throttle body. This is good news because it is a very simple fix. With the engine off, gain access to the throttle body and clean the throttle plate (front and back side) as well as the throttle bore with a soft wire brush and some throttle body cleaner. Then re install the air intake hose and and start and run the engine. It will take a bit of cranking to get the engine started because it will be extremely rich because of the throttle body cleaner. Once this works itself through the engine, it will run nice and smooth. Then allow a few hours of drive time for the throttle body and computer to relearn the idle again and that should do the trick! It is not expensive to do and it is not hard os you can do this yourself. so save a few bucks.
