Hello mustang family I bought a 1998 mustang gt and it ran like a beast when I first got it .the engine was a little dusty so I wanted to degrease the engine big mistake it runs rough and misfire I pop the hood and two of the spark plug wires had jump off so I put them back on and it ran fine but when I drove the car one of the spark plug wires had pop back off so I took the spark wire completely off and seen water in the coil pack .The water was only in the one were the spark plug wire keep popping off I got the water out and put a new spark wire on but it still pops up a little when I drive the car any help please
