My BMW XM has been experiencing rough idling lately. The engine shakes and the RPMs fluctuate when the car is in park or at a stop. What could be causing this issue and how can I fix it?
ReplyFirst, check your spark plugs and ignition coils. These are common culprits for rough idling in BMWs. If they are dirty or worn out, they may need to be replaced. Additionally, make sure to check your intake system for any vacuum leaks.
Another potential cause could be a dirty or clogged fuel filter. If your filters haven't been replaced in a while, it may be causing your car to struggle with delivering fuel to the engine. Consider replacing them as part of your regular maintenance routine.
If all else fails, it may be an issue with your fuel injectors. These can become dirty or clogged over time, causing issues with fuel delivery. Consider getting them professionally cleaned or replaced.
