What are the common issues with the Vauxhall Zafira Life engine?

I've been experiencing some problems with my Vauxhall Zafira Life engine. It's making strange noises and the power seems to be decreasing. What could be causing this? Is there anything I can do to fix it?

It sounds like you may have a faulty mass air flow sensor. It's responsible for measuring the amount of air coming into the engine and adjusting the fuel mixture accordingly. A faulty sensor can cause the engine to run rough and lose power. You may want to have it replaced.

Another common issue with the Vauxhall Zafira Life engine is a failing fuel pump. If the engine is struggling to get enough fuel, it can cause it to make strange noises and lose power. I suggest having it checked and potentially replaced.

Have you checked the spark plugs? They can get worn out over time and may need to be replaced. This can cause similar symptoms as you are describing with your engine.
