I have a 1995 Trans Am LT-1. engine was totally rebuilt recently, Mild performance with Lt-4 hot cam, double springs, ported heads and ls7 rockers. The problem is the check engine light remains on giving me code 43 (knock sensor). Ive replaced the stock knock sensor with a New 96' corvette Lt-4 knock sensor thinking it would solve this problem, which it didnt. Has anyone had this problem before? No problems with the motor at all, runs perfectly. Car does run alot smoother now that i have the Lt4 one in. Any help would be greatly appreciated as im clueless what needs to be done to solve this problem.
