spark plug wire popping out

[chronicvex]

ok i'v looked at the other threads about this but didnt tell me what i wanted to know really. The wire closest to the passenger side is popping out whenever I drive the car... I saw something about checking the pcv valve? I'm a newb.. and i'v been looking for something to tell me where it is/if theres any tricks checking it out, but cant find anything so any guidance you can offer is greatly appreciated. And im thinking about just buying the wire cover to stop it from popping out, is this a good idea or if something is wrong other then the wire failing will it hurt my car? I replaced plugs and wires about 2 months ago. ngk plugs and magstar wires. I dont know if this matters but when I was first checking it out the boot to the wire was stuck around the spark plug and I had to pull it out and put it back on the wire... but its now still popping out even with that on. Ty for any help/advice you can give.


and holy crap. i fix one thing and one or two more things gotta go bad.
