Spark plug wire keep coming off, how can I fix this?

Asked by Apr 22, 2014 at 09:45 AM about the 2001 Mitsubishi Montero Sport XLS 4WD

Question type: Maintenance & Repair

The problem I am having is the spark plug wire behind the oil fill cap keeps popping off of
the spark plug. When this happens the vehicle run poorly. I cannot figure out why this is
happening. I pushed the wire back onto the spark plug, but it keep happening. Any ideas
as to why this happens? Other than that the vehicle runs fine.

The boot must be worn, you can sometimes snug up the metal connector inside the bott by using a pair of pliers to crimp it to a small dia. or purchase a new wire, some auto parts shops sell them individual, make sure you get the rpoper length.

Thanks I will give this a shot...
