1990 Oldsmobile 98 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 1990 Oldsmobile 98

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.

The Engine Control Module (ECM) can fail causing stalling, and engine and transmission drivability concerns.

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.
