How to Troubleshoot a Ford Puma's Engine?

I've recently been experiencing some trouble with my Ford Puma's engine. It seems to be misfiring and I'm not sure what's causing it. Can anyone provide some advice on how to troubleshoot this issue?

I've had the same issue with my Ford Puma before. The first thing you should do is check the spark plugs and ignition coils. They could be the culprit for the misfiring.

Another possible cause could be a clogged fuel filter. You should also check the air filter and replace it if necessary.

It could also be an issue with the fuel injectors. It's best to take your car to a mechanic to have it properly diagnosed.
