[QUOTE="hjen27, post: 1566217, member: 38735"] I've had my 03 f350 for a little over a year now. When I first got the truck it ran well but after a few months my hpop went out. I have since replaced the hpop, the icp, the ipr, the PCM wiring harness and the PCM its self. But the truck continues to idle at 970 rpms. I kept getting codes for the icp signal being high and low so I replaced the icp again. The truck continues to idle high and surge I'm at a loss at what to try next. Has anyone had this problem?
