What causes the engine to misfire on a Ford Puma?

I have a Ford Puma and recently I have noticed that the engine has started to misfire. I have tried changing the spark plugs and cleaning the fuel injectors but the problem still persists. Any ideas on what could be causing this issue?

Hi John, a common cause of engine misfires on Ford Puma is a faulty ignition coil. It is recommended to get it checked and replaced if necessary.

Hey John, another possible cause could be a clogged fuel filter. It is important to get it replaced regularly to avoid issues like misfires.

Hi John, have you checked the condition of the spark plug wires? They could be damaged or worn out, causing the misfire.
