I need to know what causes these codes to come up. It always happens when it is below 45 degrees and I just jump in the truck & go. When I accelerate to get on the freeway it pops & bucks sets the code. Then I coast to the side & after giving it a minute & let the go out it cranks up & runs fine. I have to reset the code to make the engine light to go out. Thanks for your Input

You have a failing injector, and what I can find is most people that get these codes have an Edge Juice with Attitude.

Also the wiring to the injectors may be chafed.

Get a new valve cover gasket and check the injector wiring. If you have the EJWA, reset to stock tuning and take it off to isolate the injector harness.

My guess is you have a chafed injector wiring harness one 1 or more injectors.

IT only does it when ever it is cold. I do have a edge juice with attitude. I have also had a problem with my gauge cluster when I have it plugged in it dings and the gauges go down & back up. Thanks for the info.
