Why does my Vauxhall Corsa lose power when accelerating?

I've noticed that my Vauxhall Corsa seems to lose power when accelerating, especially on uphill roads. What could be causing this issue and how can I fix it?

One possible cause of your Vauxhall Corsa losing power could be a clogged air filter. If the air filter is dirty or blocked, it can restrict the flow of air to the engine, reducing its performance. I recommend checking and replacing the air filter if necessary.

Another potential cause could be a faulty fuel pump. A worn or damaged fuel pump can result in inconsistent fuel delivery, leading to a loss of power. You may need to have your fuel pump inspected and replaced by a mechanic.

It's also possible that your spark plugs are worn out or misfiring, which can cause a loss of power. I suggest having your spark plugs checked and replaced if needed to improve your car's performance.
