I have a 97 t.bird 4.6 seems to have a dead miss on the right side I can hear it thru the right exhost pipe changed the plugs double platinum maid no difference it has msd wires and coil pack's.. help it's diving me crazy!
you could test the coil packs...resistance from hot to ground, each one...and comparatively against one another....ex-communicate the defector~
A Power Balance test with a good scan tool will tell you instantly which cylinder is missing. You didn't mention a flashing "Check Engine" light (which would indicate a misfire as well). Are you just hearing it or is the engine performing poorly? If it's just a noise and there's no actual misfire or loss of performance, I'd turn the radio up.
