HPFP, could, or plugs...
Okay so I have a 2013 S Hatch that I bought at 36K. I have owned it for a year and have put about 30K on her. I had a coil pack go at around 50K. Previous to the replacement it had started sputtering or choking (like a misfire but no code) under full throttle. Then one day under full throttle the sputtering, threw me into limp mode and my car sounded like a diesel. I ran the codes, found a misfire, tested the particular coil for the misfire, replaced the coil, and erased the code. It was fine for another 5K and had similar issues. Got a cylinder 2 misfire. Repeated all the steps above again, except this time I replaced plugs as well. Now I am having the same problem. Weird thing is this time, there is no codes. Not through basic obd, schwabben, or my euro shop’s scan tool. So, I used obd to monitor FRP thinking that the HPFP could be the only other culprit. However, I’m running 900-1100psi on startup and between 1800-2000psi under full load. So, I’m doing my research I’m going to assume that it is not the HPFP. My question to the community is: Could my plugs have been pregapped incorrectly? Could anything have gone wrong with coil pack installation? And finally, do you think upgrading all of my coil packs and doing colder plugs will solve this issue?
