Coil pack looks okay. Plug wire show no damage, burning/melting, etc. Cant get the damn plug off though.
Going to try swapping the coil pack around to see if the code/misfire follows.
How long does it take to throw a code? Isn't it like 40+miles driven, or 2-3 full heat up/cool downs?

Moved coil over one. Cleared codes. Went for a drive and attempted a GM Driving Cycle.
Was hard to do with the road I was on. Regardless, by the time I got home, I got the P0138 code again. No misfire code. WTF. lol.
Going to let it cool down and try again later.

Update:
Long winded version-
So I just got back from Vatozone. I scanned the car before I left, no codes. Went for a 15-20 minute drive, stopped, scanned, no codes. FACK. By this time it was almost 7, and AZ closes at 8 tonight.
Drove there, parked, scanned, no codes.
Walked in, inquired about coil packs, cried a bit because of the price, and then decided to get my ICM checked. Went back outside, got 2 coil packs off and then got pissed that I couldn't get the third off without tearing up my knuckles. With like 30 minutes before closing I was like, screw it, gonna go with the coil pack. Went in, bought it, swapped it in, good to go.
Damn you coil packs!!!

Drove to Autozone, swapped in a new coil pack. That fixed the problem.

Glad you got it fixed. Sounds just like the issue with my truck luckily all 6 coils were in one unit, although it was a bit pricey it was probably less that it would have been for 6 individual ones.
