EGR valve
I ordered some block off plates from Amazon that were too small. I poked around the webz, and nothing looked like a match. I had a pack of cheese ball, Mr. Gasket pipe plugs on the shelf, so I borrowed a tap from neighbor Jimmy and sent it. Hopefully, the check engine light stays out, as ZZP was spoda do that in their "Stage 1" tune. The reason for this is the huge crack in the EGR manifold, should be visible in the pic. I could feel hot air with my finger. Last weekend, I mashed the throttle coming out of a traffic jam. It was right at the top of 1st for a downshift, it decided that the rev limiter wasn't necessary at the time, and it let out a tink, tink, tink! Then, the CEL started sending me Morse code. It was a P301 misfire, so I figured it was the huge exhaust leak.

That dang #1 misfire keeps coming back. I got the freeze frame from the code trigger. STFTs are 0%, LTFTs not so much. Any ideas? I'm thinking clogged injector....
I have the same scanner! I'd be swapping injectors, then coils, etc to see what makes the problem move to another cylinder.
I know it's not (or shouldn't be) the coil because wasted spark. If the coil was bad, it should have 2 misfires, no? There are 3 coils for 6 cylinders.
Oh, the pig. I was thinking your truck. Yeah I'd lead with the injector then unless you roached a plug wire or semi fouled a plug? For some reason I thought I was in the non G thread.
Maybe it burned the plug from the EGR exhaust leak? I've been meaning to submit that to Engine Masters: does running no exhaust really burn valves? That could be, too. There are some funny noises emitting from that corner.
