1986 Oldsmobile Supreme problems

Common 1986 Oldsmobile Supreme problems

The Oldsmobile Cutlass Supreme, produced in 1986, was a popular model during its time, with over 331,000 units sold in that year alone, making it the best-selling automobile in the United States. However, as with any vehicle, there are common problems that owners have reported over the years. Here are some of the most frequently mentioned issues:

• Carburetor problems: Some owners have reported issues with the carburetor after having it rebuilt. These problems can include difficulty starting the car, poor idling, and stalling. In some cases, the choke may not function properly, causing the engine to die when the butterfly is not held closed. It is essential to ensure that the carburetor is correctly adjusted to the specifications of the engine year, as this can significantly affect the car's performance.

• Timing issues: Some owners have reported issues with the timing of the engine after having the carburetor rebuilt. This can cause the engine to sputter and die when the timing is adjusted. It is crucial to ensure that the timing is correctly set, as this can significantly impact the car's performance and fuel efficiency.

• Rear-wheel drive platform: The 1986 Oldsmobile Cutlass Supreme was the last of the GM intermediates to roll on a rear-wheel-drive platform. While this provided a smoother ride and better handling, it also meant that the car was more prone to rust, especially in areas where salt was used on the roads during the winter months. Regular maintenance and rustproofing can help prevent this issue.

• EGR system: Some owners have reported issues with the EGR system, which can cause the engine to run poorly and produce excessive emissions. It is essential to ensure that the EGR system is correctly connected and functioning properly to prevent this issue.

• Fuel efficiency: While the 1986 Oldsmobile Cutlass Supreme was known for its smooth ride and comfortable interior, it was not particularly fuel-efficient. This can be a significant issue for owners who drive long distances or frequently commute.

In summary, the 1986 Oldsmobile Cutlass Supreme is a popular model that has its share of common problems. These include carburetor issues, timing problems, rear-wheel drive platform rust, EGR system malfunctions, and fuel efficiency. Regular maintenance and careful attention to these issues can help ensure that the car remains reliable and enjoyable to drive.
