I was all set to take the truck to the local Ford dealer, about 25 miles away, but I was worried it would quit in the middle of nowhere, which is between home and the dealer. I had another truck in the tire shop near my house, and the owner, who loves the 7.3 engine and drives a heavily modded dually, said he'd go look at my truck.
He made a few calls to friends and decided that it was worth a try to replace the computer, just to see if that was the problem. He had three units, all with different codes, out of wrecked vehicles, etc. He collects various parts, "just in case". I went to Macon, about 25 miles away, to pick them up. After struggling to get the old computer out (y'all know where they put the thing) he checked the code and found one of his three a close match. We stuck it in and all was well again
The codes were not exact, but, so far, everything seems pretty normal.
I drove to his shop to pay him and told him that the unit must have been from a fancy truck as I now had leather seats with power, a console, and 4x4
I think one of the guys hanging out at the shop believed me.
The cost for computer and labor, $250.00. I shudder to think what it would have been at the Ford place
I think we got lucky, and his diagnosis was apparently right.
But he did tell me I needed some injectors
