CEL light cycling on and off
About a month ago i was driving up a hill CEL light came on, took it to the dealer they said there was no code stored. Now ever time i pull a grade at light throttle the CEL comes on (now it shows a code of P0148) then it resets itself when i restart the truck. If i use heavy throttle going up the same hills it does not come on. (rev up shift down) I had this same code come on before with a no start, the dealership replaced all six injectors Thank you with any suggestions or input. It also does not start as good as it used too
