misfires are bad.

a misfire is when the ignition spark that facilitates the combustion process doesn't happen or happens at an incorrect time.

A misfire can be caused by many things. Old spark plugs that are not functioning correctly would probably be the most common cause of a misfire. A misfire can also be caused by incorrect gapping on the spark plug. Faulty or poorly earthed ignition coils can also also cause misfires in a perfectly new spark plug.

We need more information from you if we can give advice on how to fix it and how much it might cost.
