Question about 1989 Oldsmobile Cutlass Ciera
Changed O2 Sensor, MAP Sensor, Air Filters fine, Changed Fuel Filter...But it still Bogs down when trying to accelerate. What is the problem?
My 89 cutlass did the same thing....She would bog down ( when the service engine light came on)....Light would go off and she would run fine...Shop replaced fuel fiter and KNOCK SENSOR, runs great now, the service engine light stays off too. Ran a can of MG injector cleaner thru too.

Working on Mom's car for three days now I've just about pulled all my hair out ! The dam thing would bog as i tried to accelerate over 700 RPM. We replaced the MAP,TPS,FUELPUMP,and i ohm-ed out everything under the hood, and then i found it!! The CRANK POSITION SENSOR had cracks around the base of the sensor and had oil seeping out.Check out pic.I hope this could be of some help...

Look at how much exaust pressure is coming from the tail pipe, and if the speed of exaust increases when you step on the gas.... possibly a restricted exaust, or cat converter.
