I own a BMW car and recently I noticed that the engine has a rough idle. I tried checking the spark plugs and fuel injectors, but they seem to be functioning properly. What could be causing this issue and how can I fix it?
ReplyA rough idle in a BMW car can be caused by multiple factors. One common cause is a dirty air filter, which can result in an inadequate air-fuel mixture and disrupt the combustion process. Another potential cause could be a faulty throttle position sensor. I recommend taking your car to a trusted mechanic who specializes in BMWs for a thorough diagnostic test.
In addition to the air filter and throttle position sensor, a rough idle in a BMW car could also be due to a vacuum leak, a worn out crankshaft position sensor, or a malfunctioning idle control valve. I suggest checking all of these components and replacing any that are found to be faulty. If you are not comfortable doing this yourself, seek the help of a professional mechanic.
