Recommended Posts

i haven't messed with my battery or throttle body lately, but it seems the last few days when i start up the engine in my 88 gp le, in the morning, it revs right up by itself. any ideas?

MAFs on the 88's go out like crazy (SES light on?)

Try cleaning the IAC and Throttlebody

 

If its idling fine and not stalling I wouldn't worry about it.. my car does it too. :?

k the ses light is not on and in traffic today it heated up and then starting chugging a bit. it never came close to stallin tho.

Probably dirty or defective IAC. Clean it and your TB. Add a bottle of fuel injector cleaner to the tank as well.

actually '88 should have a MAP as they were changed over in '87 from MAF to MAP although the MAF may still be in place.

 

A good cleaning of the TB/intake before running, then start it and shoot a bunch more cleaner in the intake revving it to keep it from stalling. Put it back together and take it for a good rip, should fix that.

88 may still have MAF(my 88 GP SE had it). If it does and is the MAF, I can sell you the one from that car cheap. It works great, cars engine went and car is got stripped for parts.
