hey, I just got a 94 gt(5-speed), the guy i got it from didn't know much about it either because he just got it on a trade. anyways, by the looks of it, it has gt-40 heads, svo intake, e cam, shorty headers, msd 6al ignition and distributor.
my problem im having with it is, it's not idling right, when im stopped it will idle fine(around 800rpms), but when i go to shift from 1-2-3 etc. it steadily idled at 1500 in between shifts. as well if i rev the car to about 2500(while sitting still), it will take a while(3seconds approx.) for the rpms to drop back down to 800. i tested the tps and it read 1.15(ignition on but car off).
so i took the throttle body off, cleaned it along with the tps and iacv, put them back on and it was just a tad better. still did the rev and it will stay up in rpm thing, so i unplugged the tps and it ran fine and when i revved it, it would drop back down to where it's supposed to be. I plugged it back in and now it doesn't have a cold start idle of 1500or whatever it's supposed to be, it just starts and idles at running temp rpm of 600 now...
I would like to know if anybody knows what my problem could have been, because obviously if i didn't fix anything, the problem is still there and will come back to bite me in the butt in a little while. thank you
