To update this, I went to autozone to pull codes. P0307. No pending codes. Dude pulling my codes says, “it’s your injector. I’d put some sea foam in it to see if it clears it.” Cool thank you, but I’ll pass on the snake oil. I ordered 8 plugs and 2 coil packs with the intent of having a spare on hand. Out the door for all denso parts was $160 on Amazon. Dealer wanted $120 for 1 coil pack.
I started with passenger bank. Nothing terrible, but 3 of 4 coil packs seemed original. Picture of the non-denso/original coil, does anyone recognize the logo?
Plugs 2468 from R - L
Started on the driver’s side, all is will until I pull 5 and 7 coils
#5 (no code big crack)
#7 (code, small crack)
So I put in the “D” coil pack into 5 and the new denso into 7.
Plugs 1357 R - L
Truck drives much better on a butt dyno.
I’m going to watch my economy. I hope it gets better.
