Question about 1989 Oldsmobile Cutlass Supreme
Hello, i'll try to assist you. it sounds to me like you have a bad idle control sensor. on the top of the motor, look for a round silver canister that has has an electrical plug in. the canister will be about 2inches round & will be on the top of motor. the cost of part should be close to $20.00 the unit will have 2 screws holding it to the motor. disconnect the positive cable to battery 1st then remove the plug in to unit, remove the module[idle control sensor] by turning the screws counter clockwise.taking care not to lose the screws. replace the unit & tighten the screws to snug position, plug unit back in, then reattach the positive cable back to the battery. this will let your cars computer adapt the new sensor to the cars computer. after you've inspected to make sure the units plugged correctly, start the car, your car should run smoothly with no stop & restart. good luck and thank you for selecting fixya.com for further assistance please fell free to consult an expert again.
