...after it rains? My mustang misfires after or while it rains. I have had a code go off for cylinder 8 misfire and I've replaced the coil 3 times and the car stops misfiring for a while each time but then it rains and the misfiring starts again? The problem goes away like 2 to 3 days after its been dry? what can i do? is this an expensive fix? the problem seems to only occur within cylinder 8, all my spark plugs are new.... ford said i did not have to replace all the coils just because i was replacing 1. please do not answer this question if you do not know what COP is because that is the ignition config the car uses.
