What could be causing my Vauxhall Astra to struggle with acceleration?

I've noticed that my Vauxhall Astra is having trouble with accelerating smoothly. It feels like it's struggling and there is a slight hesitation. What could be causing this and how can I fix it?

You may want to check the air filter and fuel filter to see if they are dirty or clogged. If they are, replace them to improve engine performance.

It's also possible that there could be an issue with the spark plugs or ignition coils. Have these checked and replaced if necessary.

Another possibility could be a problem with the fuel injectors. Have a mechanic inspect them for any clogs or damage.
