How do I troubleshoot my Vauxhall Vivaro's engine misfire?

I've noticed that my Vauxhall Vivaro's engine has been misfiring, causing a loss of power and rough idling. What could be causing this issue and how should I address it?

It is possible that the spark plugs or ignition coils in your Vivaro are worn out and need to be replaced. You can have them checked and replaced at a certified mechanic or do it yourself if you have the necessary tools.

Another possible cause of engine misfire in your Vauxhall Vivaro could be a clogged fuel filter. Over time, dirt and debris can accumulate in the filter, restricting the flow of fuel to the engine. Consider replacing the fuel filter regularly to prevent this issue.

A leaky or faulty fuel injector could also be the culprit behind your Vivaro's engine misfire. If the injector is not functioning properly, it can cause an uneven fuel supply to the engine. Have a mechanic inspect and replace any faulty injectors.
