What are common causes of reduced engine power in a Vauxhall Zafira Life?

I've noticed that my Vauxhall Zafira Life is experiencing a significant reduction in engine power. I'm concerned and wondering what could be causing this issue. Can someone with experience in Vauxhall Zafira Life maintenance offer any insight?

One common cause of reduced engine power in a Vauxhall Zafira Life is a clogged air filter. This can lead to a decrease in airflow and ultimately result in reduced power. Additionally, a malfunctioning oxygen sensor or a faulty spark plug can also contribute to this issue.

Another possible culprit for reduced engine power in a Vauxhall Zafira Life is a faulty fuel injector. This can cause an imbalance in the fuel-to-air ratio and lead to decreased performance. It is important to have the fuel injectors checked and cleaned regularly to avoid this issue.

A failing mass air flow sensor can also cause a significant reduction in engine power. This sensor measures the amount of air entering the engine and adjusts the fuel mixture accordingly. If it starts to malfunction, it can lead to decreased power and even stalling of the engine.
