Question about 2002 Chevrolet Avalanche

1 Answer

The truck dies while I am driving

I have a 2002 Avalanche. While the truck is in park it runs fine. When I'm driving it will just die. Once I put the truck in nuetral (while coasting down the road) I turn the ignition and it will start again. Once its back into drive and I let off of the accelorator it dies again. Thank you for any help you can provide. KJ

I read this in a blog and it worked for my truck. I cleaned the throttle body and the air filter. It seems to be starving for air when you are just at idle cause it would not die when I was going down the road. Only if I was pulling into park with the rpms really low. Just pull the intake off and clean the throttle body. You will see a bunch of gunk. Clean it until it turns silver again.

What causes my 2002 avalanche to die after it runs for a few seconds

Loss of fuel pressure, loss of spark is likely. What you need to do is have the fault codes in the memory of the engine control computer. You will need an OBD2 fault code reader, it hooks to the diagnostic link port under the dash in front of the driver.

Why does my 91 honda accord die once i put it in drive

With auto transmitters the problem that usually will make that occur is checking on your stall converter...i would have that checked.

1986 Ford Bronco dies once it is put into gear

Sounds like a fuel mixture/vacuum problem. Vacuum advance line on the distributor could be loose/leaking/collapsed.
