Problem with car starting after h/c I had the pp ls6 style heads and the 231/237 cam installed a few weeks back by APE. Car started like crap and idled the same. Took it back over there and Kirk had the car idleing fine by changing the IAC's and drilling a bigger tb hole. Was getting the P0101 code. Fixed that. When I left APE it started dropped a bit and them found idle fine. Almost two weeks later, the car still idles fine when it finds idle, but every time you start the car, cold or hot, it runs like crap, low idle, stalls, not good. Today, I get another code, P0120 Throttle Position Sensor Performance. What does this code mean. The ses light went off tonight but the history showed this code. What do I have to do to get this thing to start at least somewhat normal.
