The cruse on my 84 turbo coupe is acting up. It won't hold speed it will slow down about 5 mph then speed back up even on flat ground. Any one have this happen before? Any idea on what might be causing it?
Vac leak?
yes, and good luck tracking it down...
If it's speeding back up I think it's safe to say it is at least TRYING to work properly. I'd have to agree with the others. Looks like the hunt is on for a leak.
