How to fix engine misfire in my Vauxhall Astra?

I have been experiencing engine misfire in my Vauxhall Astra. The check engine light is on and the car shakes when I am idling or accelerating. What could be causing this issue and how can I fix it?

A common cause of engine misfire in Vauxhall Astra's is a faulty ignition coil. You can test this by swapping the suspected coil with a functioning one and seeing if the misfire moves to the other cylinder.

Another potential cause is a clogged fuel filter. This can restrict the flow of fuel to the engine and cause misfires. Regularly replacing the fuel filter can prevent this issue.

It could also be a problem with the spark plugs. Check if they are worn out or fouled and replace as needed. It's recommended to replace the spark plugs every 30,000 miles for optimal performance.
