I just this car from a friend of mine. It has a bbk 65mm TB bbk long tubes, o/r x pipe and a sct tuner. It had a high idle issue when I bought it I had a feeling it was the iac bad so I replaced it
Nothing at all so I read about the restrictor plate guys make to fix the issue so I made one. It fixed the high idle and ran great. But it started to hang at 1500 rpm recently. Once u snap the throttle it idles back down. so I figured maybe the TB was sticking so I took a look at it but its not sticking. I unplugged the tps and it idles nice and smooth with no hang. So I checked the voltage of the tps and it reads .96 at idle. Should I replace it? Or am I just wasting my time? I would really appreciate some advice to fix this annoying problem. Thanks!
