Looking for help into why one spark plug wire on my 90 hatchback keeps getting push off the plug thereby causing the cylinder to miss. Already replaced the wires and checked the torque on the plug. Maybe someone has a clue cause I'm at wit's end. This problem started recently. The car has 125k miles is a 4 speed and other than this runs great, but this has become a pain in the butt because I have to pull over and push the plug wire back in. I even tried a hose clamp and it still comes off. Thanks in advance Lou
