My #2 cyl. is misfiring in 2002 Ford W. Changed plugs, wires, coil etc

Question

how do i solve my misfire problem?

Answer 1

HI there,

Since the ignition system doesn't seem to be the problem I would do a compression test on the cylinder that is misfiring. You could also try swapping the coil from that cylinder to the one next to it and see if the misfire moves with it. If it's misfiring at idle, you could also spray some carb cleaner along the intake with the engine running and see if the misfire smooths out, if it does, then there is a leak at the intake manifold gasket.
