Why does my BMW X1 feel sluggish when accelerating?

I recently purchased a used BMW X1 and noticed that it feels sluggish when accelerating. What could be causing this and how can I improve it?

Firstly, check your air filter. If it is dirty or clogged, it can restrict airflow and negatively impact acceleration. Consider replacing it if necessary.

Another potential issue could be a faulty oxygen sensor. This sensor measures the amount of oxygen in the exhaust and helps the engine adjust its fuel-to-air ratio for optimal performance. If it is malfunctioning, it could be causing the sluggish feeling. Have a mechanic check and replace if needed.
