Every once in awhile, while at a stop light, my idle would drop down to 400 - 500 rpm's, I cleaned the t-body,..! NOTHING! This happened even after I rebuilt it!
So, I took the idle screw all the way out, it was covered with carbon thicker than my wife's mascara! , I cleaned it up real good and sprayed t-body cleaner in the hole. I replaced the idle screw and readjusted the idle! Walla! No more low idle!
Just a little fyi!

Thanks for the tip!

 

when you would start your 3vze up after having it off for a few mins (when warmed up) would the idle be low? or if you would gas it would the idle go back up and stay there or would it drop back down to the low that it was at?

 

When I would start it up after being warm, the idle would be low, and if I gassed it, it would stay low. It was only once in awhile, probably 2-3 times a week. I have a new tps, so I re-speced that, cleaned the t-body, cleaned the egr. Finally I took the idle screw out, it was covered with carbon!
