Plug wire won't stay on

[Joe_SHO]

I have a plug wire that keeps jumping off the plug. There doesn't seem to be anything pulling on it. It's not even a stretch to reach the well. The PO said it had fresh plugs and wires. All I can tell you about the wires is that they're gray. Should I replace wires or is there something that will make it stay on?

Just checked plugs are Autolites.

check inside the plug wire, the part that clips the wire onto the plug is that little metal cap inside the rubber. You might be able to squeeze / bend it in a bit enough for it to clip onto the plugs with some needle nose pliers.

If not, I suggest either getting a whole new set of wires or buying an individual wire to replace the one that's giving you issues.
