Mein Auto: '09 BMW 328i
both was just a coincidence and there is a misfire.
I took it to auto zone, they ran diagnostics and they give code P0304 - Cylinder 4 misfire condition. Explanation is ignition system fault; probable cause is plugged or faulty fuel injector, vacuum leak, engine mechanical condition.
now what?
I was reading some other post and they suggest ignition coil replacement...I guess this would be the cheapest first try to resolve this issue.
any suggestions?
