ever since my conversion my iac has not worked properly. all the wiring is correct to the pcm because i never touched it when i did the harness. i tried cleaning the valve and replacing it with a new one. the truck wont idle correctly. my counts are around and above 200. When you let off from a rev the is closed and not controlling the idle. My tuner has been working around it but i am tired of it not controlling its self. could the pcm go bad and cause this. there are no codes being thrown. any hole would be appreciated.
