I have a 1999 ford mustang gt 4.6l 5 speed. ive replaced the spark plugs and ignition coils (THE CAR USES COIL ON PLUG (COP) CONFIG). the coil in cylinder 8 keeps going bad especially when its rainy out? should i have coated the coils with anything, no one at the car part store said a thing about this so i did not? but the car stumbles and hesitates when i accelerate.... it happened this morning when it was rainy out then late in the day the car worked fine...
