How Do I Troubleshoot Engine Misfires in My Ford Galaxy?

I have been experiencing engine misfires in my Ford Galaxy and it's becoming a major headache. I've replaced the spark plugs and ignition coils, but the problem still persists. What else can I do to fix this issue?

Based on my experience as a mechanic, I would recommend checking the fuel injectors and the fuel filter for any clogs or issues. It could also be a problem with the engine's timing. I would suggest taking it to a trusted mechanic for further diagnosis.

I had a similar issue with my Ford Galaxy and after multiple attempts to fix it, I finally discovered that it was a faulty oxygen sensor. I replaced it and the engine misfires stopped. Make sure to check all the sensors in your vehicle.
