i have a 98 blown/built/cammed/pi swapped gt and the car runs great,but the only thing is the freaking idle acts up.
on the dyno when i got the car tuned,the tuner couldn't get my idle set,because the tps was giving some crazy numbers on the laptop.
the car will surge 2 or 3 times like its gonna die,and then after that it idles perfect with a lope.then sometimes when you give it some gas and let off,the idle will hang up around 2 grand or so.the tuner thought that the tps sensor might be bad,but i changed it when i got home,and the car is still the same.could it be an egr valve or possibly an iac motor?
i was thinking maybe after i put the new tps sensor on that the tuner could possibly fix the idle but i haven't had a chance to go back up there.any help is appreciated guys.the cams are comp cams xe270's by the way.
