Intermittent Jerk/Misfire Datalog avaliable
Hi all,
I've got this strange issue where my N54 E91 wagon does this intermittent jerk/misfire in the highway. I'm starting to think this issue only occurs when the engine is warm and it's not under wide open throttle. I've cleaned my vanos solenoids and put them back in and waiting for new coils and plugs to arrive so I could replace them. Has anyone seen datalogs similar to what I'm getting? I see both Vanos intake/exhaust spike as well as cylinder timing. Fuel Rail pressure and LPFP seem to also spike at the same time. At one instance you can also see the RPM dip down from 2.5k to 1.2k in a split second https://datazap.me/u/pulstura/misfir...13-23-24-25-26 Thanks |
