What causes the BMW X3 to have a rough idle?

I recently noticed that my BMW X3 has been idling rough. What could be causing this issue and how can I fix it?

There could be several reasons for a rough idle in your BMW X3. It could be due to a dirty air filter, faulty spark plugs, or even a vacuum leak. It's important to have a mechanic inspect your car to determine the exact cause and provide a proper solution.

One thing you can try is cleaning your BMW X3's throttle body. This can help improve the idle and smooth out any roughness. You can also check for any loose or damaged vacuum hoses that may be contributing to the issue.

If the issue persists, it's possible that your BMW X3's fuel injectors may need to be replaced. These can become clogged or worn over time, leading to a rough idle. It's best to have a professional diagnose and replace them if necessary.
