Cool WTF I am going crazy

ok first i would like to thank you all for all the info on the forum. Second is my problem that i cant figure out for the life of me. Ok I have a 2001 f-350 7.3L Powerstroke with 146000 miles bone stock on 22.5 witch takes a PMT1 PCM witch when its on my truck runs like **** untill i hit 1500RPMS (My RPMS bob up and down with hesitation until 1500RPMS) But if i put another computer in with is a VDH5(2003 PCM) it runs fine except water in fuel light the check engine light never turns on so i don't know where to start.



Any help will be greatly appreciated

Try cleaning your accelerator position switch. It worked for me but I know it is a long shot.

have you had a chip or programmer on it?
when i bought a used edge and put on my truck i got the water in fuel light. it idled like crap and wouldnt go into drive. i ended up sending my pcm to jody at DP and getting it reflashed. that fixed all my problems

maybe you can send your stock pcm in for reflash and ride on the other one until you get it back.
