my 1989 chevy suburban with TBI wont run at worm idle.
my 89 suburban will start up and run fine when the computer is in in cold
mode, but as soon as the computer goes into worm mode the engine stalls
and dies. if you hold the rpm's up the car runs fine. on the highway the car
runs fine, stop at a stop sign the car dies. i have replaces pretty much all of
the sensors for the TBI and have even tried sea foam. i also put in a new
fuel filter, the old fuel filter was't even cloged up. nothing seems to work!
please help me out!
Check for vacuum leaks and the pcv
i already replaced the pcv valve and checked all the vacuum lines. No leaks, i even sprayed carb cleaner around the throttle body gaskets and head gaskets. There was no change in tone in the motor so the gaskets are fine
Advance the timing slightly. Or your idle adjustment is off.
You don't adjust idle on a tbi engine
