Spark plug wire pops out.

[D1SR240]

My 4th cylinder spark plug wire keeps comming loose from the spark plug once in a while and I have to push it down again. It's only cylinder #4. Any ideas on how to stop it from popping off?

Try some glue I guess.Sounds like you need new spark plugs wires...So worst case scenario you just got to scrape some glue off your valve cover..or gasket sealer etc...Never heard of it jus tpopping up.Mine takes some force.

length of wire too short? does your motor move excessively due to worn out motor mounts?

Is the plug tight? Could be compression leak around the plug seal blowing it off. The rubber bung at the top of the plug wire wouln't let any air by so it could be blowing it off.

Not to threadjack...

My #1 plug wire is stuck. This isn't causing a problem right now, but if I ever have to change plugs it's gonna p*** me off. Anyone know why this could be happening?

I'll check and make sure my plug is tight, that might be the problem.

the little clip at the bottom could have gotten bent as well. Take a pair of pliers and crush it a little and see if that helps. You should hear a clicking noise when you press it onto the plug.
