Maybe I misheard my friend when he told me hte codes. I should get the truck back today and will take it to the dealer to find out about the problems. Thanks for the info.
A friend borrowed my truck. On his way back to Panama City Florida he got a check engine light. He went to the nearest dealer (around Montgomery Al.) and was tole the codes dealt with the load he was pulling and another dealing with the injectors. Then told him it would be safe to drive home...
