My fuel trims are also sitting at 25 which seems to be very low. I actually do most of the work on my car besides things like alignments, been a big tuner since I was 16 owning a 1986 944 then entering the 4g63 world now getting back into a german car instead of jdm. I have an extended warranty for another 15k miles currently sitting at 60k so I took advantage of that but I'm unsure why its getting missfires now. I had the car in georgia and it ran fine on 93 or e85 never any issues. I come up to oregon and only have 92 available but occasionally add some octane booster. Could the 92 octane be causing this big of an issue or is it just time to replace things. I had 3 injectors replaced and and several other things by BMW everything else was inspected and in good condition.
