checking iver the engine doing a wiggle test and when i wiggle the wires going into the coil pack the engine will suddenly die.. then it might start back up and if not ill have to wiggle the wires around until it will.. it hasnt died on its own yet but im afraid it will while im driving at some point.. can i just cut the end off and wire on a new connector end or is there reson thats bad? i can solder on the new end and shrink tube it on
