Why am I experiencing poor engine performance in my Vauxhall Insignia?

I have noticed that my Vauxhall Insignia is not performing as well as it used to. The engine seems to be struggling and there is a decrease in power. What could be causing this issue?

One possible cause could be a dirty fuel filter. It is important to regularly clean or replace the fuel filter to ensure proper engine performance.

Another common issue is a clogged air filter. Make sure to check and replace the air filter as needed to improve engine performance.

Low fuel pressure can also lead to poor engine performance. Have a mechanic check the fuel pressure and make any necessary repairs.
