1982 Cruise Control Issue

[Dennis F.]

My recently resurrected 82 (35,000 miles) has displayed an interesting problem when you set the cruise control. Once set, it very slowly continues to accelerate. Not something that is immediately attention-getting, but once you're paying attention to it, it's obvious. Set it at 60, and watched it slowly creep to 80 in 5 minutes or so. Even going downhill you can feel a slight acceleration.

Any ideas? Vacuum leak? Transducer? Servo? Any adjustments rather than replace parts?

Thanks,

Dennis Fisher

Interesting problem Dennis. I'll give your post a bump, someone should be able to offer suggestions.

My mind is a little foggy, but there is an adjustment to take care of that problem. I believe the adjustment screw is in the vacuum connection from the engine. It should have a slotted screw in there. I do not remember which way you need to turn it, but I do not think that it take much either way to make quite a bit of change

Thanks, we'll take a look at that.

Dennis vac. port C on transducer is where the adjustment is. But make a few other checks first, vaccum hoses and make sure the speeo. needle is not jumping around, possible binding cable or kinked.these will cause problems with speed fluctuations.
