When i set my cruse it drops about 15 miles an hour then it holds that speed until I bump it up. What is the fix? 85 R/C.

AE,

Looking through the '85 FSM, the diagnostic flow chart lists the following probabilities:
1. Improper adjustment of speed control throttle cable
2. Vacuum leak
3. Improper speed control servo lock-in adjustment (max 2 turns in either direction).
4. Defective servo.

I'd say it'd be either 1 or 2 above because the lock-in adjustment, as the manual says, only corrects for minor speed variations, hence the 2 turn max adjustment.

I say it's a vacuum leak like on mine. My baby idles at around 550 RPM in gear with a/c turned on. I figure what the heck, it saves gas.

but yeah, I have to push my "speed up" button about 7-8 times to get it to maintain 65ish.

I keep saying I'll redo the vac. lines one of these days... ;)
