When I start my BMW M4, the idle seems rough and the car shakes. What could be causing this issue?
ReplyThis could be due to a dirty air filter or spark plugs. Try replacing those and see if it improves.
Another possibility is that there is an issue with the fuel injectors. You may need to have them cleaned or replaced.
It could also be a problem with the engine's sensors. Have a mechanic run a diagnostic test to determine the exact issue.
