Ive been experiencing the glorious misfires on 1 3 and 4, i was curious if anyone on here has solved this issue by replacing their primary 02 sensor? I have an 06 and know the 06 and 07 years have had a good amount of issues. Im waiting on a oil line for my turbo that i should be getting in the next couple days before i start diagnosing. I did change the coil pack from 1 to 2 and cleared the codes.
