everytime i rev the motor and it return to idle it almost stalls like damn close. I have a 85 gsl-se FI 13B. could it be just a gunked up throttle body? or is it mayeb electronic? thanx for any help.

 

There's several little things that can make a GSL-SE run funny. I switched to a carb before i ever even drove mine so I haven't paid much attention. But it's been well covored.

Try searching for things like TPS, GSL-SE rough idle, and maybe for some of Longducks old posts.

 

ok thanx

 

Ive had simmilar problems before. It could be the TPS or it could very well be the air flow meter. if it is the AFM, then it will get gradually worse untill it stauls then starts reving like magic and just pissing you off. Then it will quit for a day and start doing it again.

 

so then the fix would be? i tried cleaning the throttle body and it seem to get worse, and all i did was clewan the butterflies. then it started surging. never did this befor etill i started to mess with it. thanx

 

Try cleaning the TB again with TB cleaner with lubricants. I would also make sure to spray a little lube around the outside of the butterflies.

As for the AFM make sure the flapper door opens easily.

Definitely make a TPS tester. This cost me about 6 bucks and helped me tune out some of the backfires.

Good luck and let usu know what you find out.
