Just so happens one trip I disconnected/ sprayed external connector and cleaned side of block. Wife shouted for supper, well after supper, beers and BS I closed hood for the night. Left the next morning got loaded 300 miles away then it occurred to me what I had done; then she went back to acting up again.

It may have had a code but I have yet to get insight ( hopefully on visit south I will), local shop changed an injector and harness while I was off in another truck, so code may have been hidden in file and they did not say!!!

Truck did improve slightly on fuel, plus power.

ok awesome thanks i will take a look when the rain stops thanks again for the help!
