Yep, another misfire thread. I've searched, but haven't really found the solution.
The car misfires in 4th gear or higher starting at about 2,250 RPM, eventually tripping a code for cylinder 5. The car has 51k miles on it now. What I've done so far to try and diagnose this problem:
- Replaced all 6 spark plugs, no change at all
- Swapped coils 2 and 5, misfire stayed on 5
- Replaced number 5 injector with brand new part, updated coding, and double checked all injector values with INPA
Have not cleaned/swapped VANOS solenoids or checked/cleaned the intake valves yet.
I hit enough random buttons in INPA to get a freeze frame out of the DME for the most recent misfire event, but I know a total of two German words. Does anyone see any clues in this data?
