Hey guys hows it goin. I got a problem with my car not wanting to idle. I had a 76mm mass air on it and it made my car run like crap so i put my stock one back on and now when my car gets warmed up it idles at 1200rpms if i loosen the throttle screw to get it to come back down all it will do is surge up and down. It also does this when I come to a stop in my car. I am stumped. I have tried adjusting my tps but it didnt work out. What part number is on the tps of a 90 gt. Also I have tried adjusting my base idle first, but it doesnt seem to help. Please help me out guys.
