Inline cylinder four wheel drive.
no check engine light or codes. The engine is constantly trying to shut off when vehicle is at idle with A/C or defrost on. It is a hundred times worse when going through a car wash!
had the throttle body removed and cleaned by a reputable shop (had the battery disconnected for twenty minutes while they were cleaning the throttle body) no change.
had throttle body replaced with official AC/Delco throttle body, still no change.
Tries to die, you feel the entire truck shudder, see the rpm's go down to 300, then rev up over 1,000. Keeps repeating this behavior constantly when the A/C or defrost is on and you are in a car wash, still does it outside of a car wash, but not as bad.
have the same problem?
