What Could Be Causing My Vauxhall Astra's Engine to Run Rough?

I recently noticed that my Vauxhall Astra's engine seems to be running rough and I'm not sure what could be causing it. It idles a bit erratically and I've noticed a decrease in power. I've kept up with regular maintenance, so I'm not sure what could be the issue. Any ideas?

It sounds like there may be an issue with your fuel system. Have you checked your fuel filter or injectors? They may need to be cleaned or replaced.

Another possibility could be a problem with the spark plugs or ignition system. It's important to keep them in good condition for proper engine function.

You should also check all of your engine's sensors to make sure they are functioning properly. A faulty sensor could contribute to rough engine performance.
