I will try to keep this short, but thorough. I have a 2001 F250 that I converted from an auto to a 6 speed. About a month ago, it stumbled a few times, off and on then died while slowing down for a turn. Restarted fine. I am running an Edge Evolution II, but just as a monitor. I used it to check for codes. No codes. I figured it was a CPS so I pulled out my handy dandy spare. Truck ran fine for a week or so. Did the stumble again while backing up to a trailer. This time had some strange codes. I wrote them down, but my wife threw them away for me. One code had something to do with the barometric sensor, which I understand to be in the PCM. The other code had something to do with dual alternators, which I don't have. Truck ran fine for a few more weeks. Yesterday, truck felt down on power and was running kinda "rough" at freeway speeds. Then it died while exiting the freeway. Tried to scan, but I had no power to my Edge. Radio was still on though. Finally restarted after about 5 minutes. Scanned it at work. CPS code. Replaced it with my new handy dandy spare. On the way home from work this morning, it would stumble and act like it wanted to die occasionally. I am running the auto PCM, but Matt at Gearhead wrote some tunes for a chip that uses manual tuning. I thought it was possible that the chip was bad, but I can't unplug it because it will for sure run bad because the PCM will be back to the auto tune. I pulled the chip and made sure it was good and solidly connected and clean. It was. Could the chip be bad? It has been running great for about a year since I did the swap. Could it be the PCM? My brother said it sounds like when his 99 PCM bit it. Is there any way to test the PCM? Can the dealership test it? I really need to buy AE. The only other code I ever get is the KAM code, I believe it is P0603? I understand that this is common with a chip and it has popped up off and on forever. Any ideas? I am at my wits end. I am about to pull my hair out and at my age I need what few hairs I have left. Sorry for the long post, but I just wanted to paint a good picture. Thanks in advance!!!
