Common Causes of Engine Misfiring in the Vauxhall Insignia

I have noticed that my Vauxhall Insignia is experiencing engine misfiring. What could be causing this issue and how can I fix it?

Hi Andy, engine misfiring in the Vauxhall Insignia can be caused by a few different factors. One of the most common causes is a faulty ignition coil. This can be replaced at a relatively low cost.

Another possible cause is a clogged fuel injector. This can be resolved by using a fuel injector cleaner or getting the injectors professionally cleaned.

Low fuel pressure can also lead to engine misfiring. Check your fuel filter and pump to make sure they are not clogged. If they are, replace them.

I also suggest checking your spark plugs and wires. If they are worn or damaged, they will need to be replaced. This can improve the performance of your engine and reduce misfiring.
