Problems with anti-theft systems using the raised-chip key can prevent the car from starting. The wires in the steering column to the ignition lock cylinder tend to break. The key and ignition lock cylinder should be replaced to correct this condition.

1991 Oldsmobile 98 Problems
The cam sensor interrupter (magnet) may become demagnetized and/or fall off of the camshaft gear causing the Check Engine Light (Service Engine Soon) light to illuminate. On higher mileage vehicles it would be advisable to replace the timing chain and gears if this problem were to occur as the timing cover must be removed to replace the interrupter.
The fuel pump can fail causing the engine to stall and not restart. Our technicians highly recommend to replace your fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.
A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.
The mass air flow or crankshaft position sensor may fail causing the engine to stall intermittently. Proper diagnoses will be necessary to determine the cause of any stalling condition.

1991 Oldsmobile 98 Reviews
I have no clue how many miles the car has because the entire digital dash quit working. The air-conditioning doesn't work either and a ton of other things. Now, I've been told the head gasket is starting to go which will cost more to fix than the car is worth! On the up side it is a comfy car with lots of leg room and head room. It drives smooth and it's a pretty quiet car. When it shifts it doesn't jerk around which is nice and mine still has the original sound system which sounds pretty good. It steers like a dream and I could probably drive it with one finger (except that's not too safe ^_^).
