good day, need a bit of help here. got a 92 t/a lb9-tpi 5 spd. its a 50,000 mile car. the prob. is after it comes up to temp. with like 5-10 miles, when you pull to a light or sign, it idols for a few seconds then stalls out. from there it only gets worse, and every time is a lil bit harder to start. when i read it with a code reader, it comes back clean, " no trouble codes". does anyone here have an idea what to look for to help resolve this?...... i did just put on a new gm tps thinking it might be it, but no luck there. all help is appreciated!!!!!!

 

Take the vacuum source off your egr valve, You can do it at the bottom of the throttle body. Just make sure to plug the hole ( on the throttle body ). If that cures it, you need a new egr valve as the spring is wore out.

 

hey gmgod, thanks for the tip. i'll try it asap and let ya know.....
