How do I troubleshoot engine misfire in my Vauxhall Zafira Life?

My Vauxhall Zafira Life seems to be experiencing engine misfire. I've noticed a decrease in power and a rough idle. What could be causing this issue and how can I troubleshoot it?

Engine misfire can be caused by a variety of issues, such as faulty spark plugs, a clogged fuel filter, or a malfunctioning ignition coil. I recommend checking these components for any signs of wear or malfunction. Additionally, make sure to monitor your fuel levels as a low fuel level can also contribute to engine misfire.

One potential cause of engine misfire in your Vauxhall Zafira Life could be a problem with the fuel injectors. It's important to regularly clean and maintain your fuel injectors to prevent any blockages or malfunction. If the issue persists, it may be necessary to replace your fuel injectors.

Another possible cause of engine misfire is a malfunctioning oxygen sensor. This sensor is responsible for monitoring the air-to-fuel ratio in your engine, so if it's not functioning properly, it can lead to misfires. I suggest checking and replacing your oxygen sensor if necessary.
