How do you get them off the old cap without damaging them, or do you just toss the wires and replace? I bought plugs, cap and rotor as the car is new to me and I have no record of their replacement. Car runs ok except for a brief stumble on start that goes away immediately.

Also, the black cap-shaped cover is cracked, can I just glue it?
