I replaced the 4 coils on bank 2 tonight. Now when I replug the MAF, I have misfire codes showing on bank 1!
I will go for a drive and confirm if codes are back on bank 2 or not. But when I tested quickly at idle, I only had misfires codes on bank 1: P0300, P0301 and P0303.
I also pulled a P1602, will check to see what it is, I got it once before.
I will also test the resistance on the coils. Interestingly, the resistance on the 4 new coils was the same as 2 coils I have lying around but it seems different than the one on the coils that were on the car, particularly cylinder 5. I will re measure everything to be sure and post a feedback.
