1999 Cadillac Seville STS 4.6L Idles at 2000Rpm
supposedly when the pcm is replaced car runs fine for a couple days then high idle starts happening. we blocked off the air intake and the engine stalled so no vac leaks present. We can't get the IAC to respond and it is stuck at 157 never moves. tps is at .73...
