Hello guys.
Going home from work today I got a flashing cel, code p0302. This is the second time I had a misfire, last time was about a year ago, I'm not sure though if it's the same code. Last time I took it to the dealer right when it happened as I was nearby. They told me one of my coils had gone bad and that they needed the originals as I have the BHR ignition installed. I didn't have them available at the time, but they came to the conclusion that it was just a bad connection in one of the ignition cables since everything was fine when they put everything together after doing some testing and everything's been working fine ever since until today. One or two times since then I have gotten a p0420 code when cruising at highway speeds for longer periods of time (>30 mins). I visually inspected my cat which was fine and i've passed all the inspections where they measure exhaust levels since then, and the code went away after just a couple of days by itself so I came to the conclusion that it was just occasional and nothing to worry about. I have the BHR catted midpipe as well i might add.
So here I am today with a new misfire. A few minutes before the cel showed up the car was "jerking" during some accelerations and sometimes I had to give some extra gas going uphill, but it returned to normal when the road leveled out. So where do I start? Coils? Plugs? Wires? Cat? I'm eventually going to take it to the dealer but I want to have some idea about the cause beforehand since I don't really trust those guys. Please tell me I haven't fucked something up myself. :crying: The car only has about 47.000km on it (about 29 000 miles?).
Thank you, you guys are the best!
