How can I improve the performance of my Vauxhall Corsa?

I recently purchased a Vauxhall Corsa and have been experiencing some issues with its performance. The acceleration seems to be sluggish and the engine feels underpowered. I have tried changing the spark plugs and air filter, but the issue still persists. What else can I do to improve the performance of my car?

Have you checked the condition of your fuel filter? A clogged fuel filter can impact the performance of your engine. I would recommend getting it checked and replaced if necessary.

Another potential issue could be with your oxygen sensor. A faulty sensor can cause your engine to run inefficiently, leading to poor performance. I suggest getting it checked and replaced if needed.

You may also want to have your car's computer system scanned for any error codes. This can help pinpoint any underlying issues that may be affecting your car's performance.
