Question about 1989 Oldsmobile Cutlass Ciera

1 Answer

After changing most all sensors but not EGR timing sensor, changed fuel pump, EGR valve, and added new computer the 1989 Olds Cuttlass Supreme SL 2.8 engine starts, does not keep an idle after starting, started and stalls. Won't go around the block, with no noticeable vac. leaks. What can I try next. Computer code was 33 but I disconnected the EGR valve when after installation of the new computer the car did not start. After reconnecting the EGR, engine started but the problem continued and the engine sounds like a 'washing machine' at idle. I am $700 into this problem.

Check the CO/Temp sensor in the exhaust manifold. It may tell the ECU that the engine is hot when it is cold or cold when hot, getting the mixture wrong.

1989 olds regal 88 3.8 v-6 car runs great but while driving it will stall out changed coil ,egr valve and fuel pump . seems to be mainly when its warm


I would believe the problem lies with the CRANK POSITION SENSOR. The computer relies on that sensor to advance the timing when the engine is cold, once the engine warms up, the computer will ****** the timing and then the timing will be set in relation to the THROTTLE POSITION SENSOR. The crank position sensor costs aroung 30 to 40 dollars. But to have it installed will cost probably around $300...maybe more. To install the CPS you will need to jack up the front of the car, remove the passenger side front tire, remove the plastic splash guards, remove the serpintine belt, remove the harmonic balancer with a special puller designed for that type of engine, then finally, remove two little bolts holding on the sensor and replace it with a new one...........it all sounds pretty easy and straight forward, but really there is not too much room for tool movement and your body will be in an awkward position most of the time. I can do this job in about an hour and a half only because I have done it so many times and know exactly which tools are best suited for each particular bolt and the whole process, I would say it is a 3 hour job if you are very mechanically inclined or a 5 hour job for the first timer.. ,
