Help us help you. By posting the year, make, model and engine near the beginning of your help request, followed by the symptoms (no start, high idle, misfire etc.) Along with any prevalent Diagnostic Trouble Codes, aka DTCs, other forum members will be able to help you get to a solution more quickly and easily!
Ocassionally but not always, the car will misfire in higher gears under heavy load. Usually gears 3 and 4. Sometimes it will happen enough to throw codes for misfires and put me into limp. This log didn’t put me into limp, but definitely misfired a bunch.
Suspicions:
I’m still running stock coils and making 2x stock boost levels. Could be time to upgrade these.
Possible Low pressure fuel pump. Looking at rail pressures, they seem to be fluctuating down during high load. My HPFP was replaced under warranty years ago.
Injector. I don’t have the latest injectors from bmw, i have index 7s and 8s. The latest are 12s. Maybe i have a leaky injector or a clogged injector. Ocassionally when i go in my garage to start the car, i smell some gasoline. Maybe this is just some gas in the DPs? Idk.
