I have 1999 chevy silverado with 5.7. Motor runs smooth until you come to a stop.
The idle drops to barely running and is rough. Take off and runs well. Why is it
running rough at a stop
Time for a tune up? Get things checked out...
A bad Intake Air Control (IAC) valve has this symptom. Wouldn't hurt to clean the throttle body and MAF sensor, clean/replace air filter.
