Hi everyone first day on this forum still figuring everything out! I have a 2010 vw Jetta Wolfsburg 2.0l T 6 speed, 70k miles great condition, but I’ve been having issues with. It started with heavy and shakey Idling, then check engine light. So I scanned it got error code p0301 which was misfire cylinder 1. Changed out (what I believe were the original) spark plugs and the car drove a lot better, check engine light stayed on. Same day went and bought four new ignition coil packs thinking maybe one of the coils was causing the problem, the car again drove a bit better but the light stayed one. About two days later the light went off and I thought maybe the problem was solved. Had no problems for about 4 days then yesterday when I was on the freeway everything was fine I shifted to 6 gear gave it gas to maybe 3k rpm and the car started shaking really bad, loosing power, and the check engine light started flashing along with the EPC night. At the time when I downshifted to 5Th gear everything was fine I could accelerate. Park the car last night didn’t do anything drove it this morning about a mile it was all fine, took it t Park the car last night didn’t do anything drove it this morning about a mile it was all fine, had a friend look at it and started stuttering and loosing power just like on the highway but through second third and fourth only under acceleration? scanned the car aging the code came back again to misfire cylinder one, I changed around the ignition coil packs and changed the first one but that didn’t clear the code. After driving for maybe another 10 minutes the code came back to misfire cylinder 4, then back to cylinder 1? Any thoughts?
