I have an '87 Olds Calais 3 liter engine that idles rough, hesitates on acceleration, and just recently stalls and won't start.


Karl, have you confirmed good fuel pressure? It sounds like a weak fuel pump to me. Is your Check Engine light on? If so what are the codes in the computer?

Engine shut off at 4000rpm


this sounds like an electronic problem. the control unit thinks about 50000 cycles in a second. it's bound that there could be a problem. a second hand black box or computer box should fix your propblem. goodluck

Engine bogs out,dies over 4000rpm,after10 or20 mins.it will start


When the car is in its failure mode, have someone man the accelerator and listen at the tailpipe. Have the helper gradually raise engine RPMs and see if the normal muffled sound of combustion turns into more of a hiss.
If the catalytic convertor has failed, it may have lost chunks of ceramics that are clogging the rest of the exhaust system.

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

Not idling smoothly, sometimes having to restart at a stop w/ tranny in drive.


sure, that could be it. I would also suspect the fuel filter as well.
