rough idle as in bounces around in a range of maybe 200rpm when idling, not major shakiness
sometimes after a hard acceleration the car starts misfiring alot for the next 5-10 minutes everything stock spark plugs just replaced and vanos solenoids cleaned to no avail and oil change has been done regularly since its random misfire, I kind of doubt it coils or injectors cause they wouldn't all go bad at once and also I think alot of common issues would trigger specific codes maybe let me know what you guys think thanks (09 335xi) |

Read the codes to find out which cylinders misfiring, then swap coils to rule them out first. |
