Then the next morning started the truck up let it warm up started down the road and it died. Let it sit for awhile it started and had no power until about 2200 RPM's. I've got an edge scanner and the codes it gave me are PO603 and PO606 pcm. Any help for my 97 powerstroke?
Ok P0603= PCM Error, P0606= PCM Processor Fault.
So I'm thinking there is something wrong with your pcm.
