JACUSTOMER-nfmdr63n- :

Cylinder missfire

Enes : If you have misfire most common is bad spark plugs and bad ignition coils
Enes : If you have new spark plugs then you need all new ignition coils
Enes : to test pull out coil and slide rubber boot down around the ignition coil you will see most hair line crack on coils indicating blown coil
