What could be causing my Vauxhall Insignia's engine to misfire?

I've been experiencing issues with my Vauxhall Insignia's engine misfiring, especially when accelerating. It also feels like the car is struggling to maintain power. I haven't noticed any strange smells or noises. Does anyone know what could be causing this and how to fix it?

Hi Joe, it sounds like your Vauxhall Insignia may have a faulty spark plug. It's a common issue that can cause engine misfires and power loss. I would recommend taking your car to a mechanic to have the spark plugs replaced and the engine checked.

Hi Joe, another possibility is that your car's fuel filter needs to be replaced. A dirty fuel filter can lead to poor engine performance and misfires. I would suggest getting it checked and replaced if necessary.

Joe, have you checked your car's ignition coils? They can also cause misfires if they are faulty. Get them inspected and replaced if needed.
