"what are the most common problems with the 1987 Oldsmobile Cutlass Supreme?"

Question

Accepted Answer

The 1987 Oldsmobile Cutlass Supreme is generally sturdy, but owners report a few repeat trouble spots:

1. Stalling in gear – usually traced to a mis-adjusted choke, dirty carb, or cracked vacuum lines.
2. 200-4R automatic transmission – soft 2-3 shifts and eventual overdrive clutch failure if the TV cable isn’t adjusted perfectly.
3. Digital-dash (if equipped) – failing solder joints can make the speedo/tach go dark; re-flowing the board usually fixes it.
4. 307 V8 intake-manifold gasket – oil seepage/ coolant seepage after 80 k miles; replacement gaskets solve it.
5. Rear frame rails and body mounts – G-bodies love to hide rust there; poke before you buy.

Those are the big ones we see in our market listings and club forums. If you’re looking at the blue ’87 coupe on our site, it’s listed as “Original & Highly Original,” so check those vacuum lines and frame rails first. Want help finding similar Cutlasses or need parts sources? Just let me know!
