I recently noticed that my BMW M3 has a rough idle at start up and sometimes while idling. What could be causing this and is it something I can fix myself?
ReplyThere are a few potential causes for a rough idle in a BMW M3. It could be a problem with the fuel injectors, spark plugs, or airflow sensor. It's best to take your car to a trusted mechanic to diagnose and fix the issue.
One common cause of a rough idle is a dirty or clogged air filter. Make sure to check and replace the air filter regularly to avoid this issue.
Another possible cause is a vacuum leak. Check for any cracks or leaks in the vacuum hoses and have them replaced if necessary.
