I recently noticed that my BMW M3 is having a rough idle, and I'm not sure what could be causing it. Can anyone help me diagnose the issue?
ReplyA common cause of rough idle in BMW M3s is a faulty mass air flow sensor. It's important to have this checked and possibly replaced by a professional mechanic to ensure proper engine performance.
Another possible cause could be dirty or clogged fuel injectors. It's recommended to have them cleaned or replaced to improve the engine's idle.
A worn out spark plug can also contribute to a rough idle. Make sure to have your spark plugs checked and replaced if necessary.
