OK so I got my 87 turbo tuned and idleing(sp?) great a while ago. Problem is tht some times after it is fully warmed up. It will idle at like 1200rpm. If I use my foot and put it UNDER the throttle, and pull up on it, it goes back down to the 775 I have the damn thing set at. Now it does this with or without a/c on, fully warm, and is constant, as in it will idle at the 1200 for a full stop light. Some stops, it is the 775 for the whole time, some its 1200. And it goes down each and evey time i "pull" it up with my toe.

So is the throttle cable sticking or maybe its something on the TB or accelerator pedal? Where do I start my search?


Thanks

Mine will do the same sometimes. I think it is the return spring on the TB. Loosen your throttle cable a bit, and when it happens again check to see if it is loose. Then you will know it is the return spring on the TB. I have been thinking about just putting another spring on it like an old carb. engine. Good luck.

 

I'll try and check that in the next few days.

Im still in the process of moving
