https://www.ford-trucks.com/forums/1...ire-p0353.html This is a link to the thread I started about my problem. It has info about the diagnostics I performed. I believe I may need a new PCM. I am hoping there is something I missed instead of having to replace the PCM. If I do need a new PCM, will a used unit work? What's the cheapest way to go? Any help greatly appreciated.
