I'm back for round #2 on this question. Last time, there was a suggestion that my ECU may be bad (O2 voltage divider issue). Any additional suggestions? I haven't had time to borrow a DMM to check this suggestion.
Symptoms:
Often, when I start my '94 9KCSET (111Kmi) and the engine is cold, it will stall after idling for 1 minute or so. If I try to drive it w/o warming it up, it will buck and stall and lose power until I coax it down the road a bit. The idle will also bounce around a fair amount until warm (800-1500rpm). Once the car is warm, it really doesn't have any issues--runs well.
Attempts to fix problem (expensive shots in the dark, mostly):
new O2 sensor, new air temp sensor, new coolant sensor, new vac lines, cleaned throttle body, & new properly gapped plugs, plus other more general tuneup stuff (fuel filter, air filter, etc).
Any suggestions on what to check/replace, next???? Thanks for your comments!
