C.O.P. - (coil on/over plug)
PLUG - Sparkplug - inDhead~CopDcover.
Thought we covered that.
We just told you how to fix , cause , you asked.
You have a "Coil On Plug" system in the 03 . It's common for a plug or coil to go bad every now and again..That's what were getting at . Misfiring for long periods of time is bad for the cats. PO301's Injector is probably good, but dumping raw fuel down #1. You need to fix it.
You have the code #1 's first one pass. side (towards the front of the truck.).. After time goes by , your PCM may shut down your injectors in an effort to protect your CAT's - so, yeah , try a plug and a COP from Auto-Zone.
COP's
PLUGS
Heres a pic of #1 - The one you need to fix -
A pic of injector #1 - down by the oil filler cap - that orange thing sprouting from the fuel rail and blowing un-burned fuel thru #1 . The COP and Plug are behind that out of view.

He said there was no change unplugging the injector. ???? Significant change when unplugging COP. AND , it's missing at idle..I realize COPs miss under certain load values, this ones misfiring at idle , it has no fuel to ignite or very little..Therefor primary and secondary are good. His injector F'ed..
