How can I troubleshoot issues with my BMW 1 Series's engine performance?

I've been experiencing some issues with my BMW 1 Series's engine performance. It seems to be running rough and lacking power. Can anyone offer any advice on how to troubleshoot and potentially fix this issue?

First of all, I would recommend checking the spark plugs and replacing them if necessary. Sometimes worn or fouled spark plugs can cause engine performance issues. Additionally, it may be worth checking the air filter and replacing it if it is dirty or clogged. If these basic maintenance tasks don't resolve the issue, it may be worth bringing your car to a certified BMW technician for further diagnosis.

I had a similar issue with my BMW 1 Series and it turned out to be a faulty fuel injector. If you notice any rough idle or misfires, this could be the culprit. I would recommend getting it diagnosed and replaced at a reputable repair shop.

Another thing to check is the fuel pump. Sometimes if it is not delivering enough fuel, it can cause engine performance issues. You may also want to check the fuel filter and replace it if necessary.
