1986 Oldsmobile Cutlass problems

Common 1986 Oldsmobile Cutlass problems

The Oldsmobile Cutlass Supreme, produced in 1986, is known to have several common problems based on complaints from owners. This article will discuss these issues in detail, focusing on the root causes, symptoms, and potential solutions.

• Engine knocking and rough running: A 1986 Cutlass Supreme may experience engine knocking and rough running, which can be caused by ignition issues. When some cylinders start misfiring, the oil warning can be triggered. Check the coil towers and the spark plugs for faulty components and replace them if necessary. If no problems are found, the ignition module, located under the coils, may have failed. Have it checked and replaced if faulty.

• Power loss when going uphill: A weak fuel pump can cause a loss of power when the engine is under load, such as going uphill. Plumb a mechanical fuel pressure gauge into the oil pressure switch port and run the tube into the cabin so the gauge can be watched while driving. If the pressure drops, then the pump is failing and needs to be replaced.

• Airbag warning light and horn issues: If the airbag warning light remains on after the engine starts and the horn is not working, the problem is usually with the clock spring connector under the steering wheel. It will have to be replaced, which requires the steering wheel and airbag to be removed. Due to the hazards of removing the airbag, the repairs should preferably be done by a qualified mechanic.

• Front right wheel bearing play: A 1986 Oldsmobile Cutlass may experience a feeling of going over bumps while driving, even when the road is smooth. This can be caused by a front right wheel bearing with 1mm or more of play. To address this issue, the wheel bearing should be replaced.

• Transmission solenoid issues: The lock-up solenoid in the transmission can fail, causing issues with the transmission engaging and disengaging. If the solenoid is toast, an aftermarket one should be sought out, as GM ones are scarce. If the issue is not with the solenoid itself but with the transmission/ECM circuit, the problem may require more extensive diagnosis and repair.

• Tail light wires shorting out: The tail light wires in the 1986 Oldsmobile Cutlass are known to short out. This issue can be addressed by inspecting the wiring and repairing or replacing any damaged components.

In conclusion, the 1986 Oldsmobile Cutlass Supreme has several common problems that owners may encounter. Understanding these issues and their potential causes can help owners address them effectively and maintain the vehicle in good working condition.
