Made me chuckle with the wash to much comment, need that after being frustrated.

 

The wire needs to "snap" on the Plug end. Other than that and it appears when ya wash it, it may be the Coil, Coil wire etc getting water in that area. Trace out the Wires and make sure both ends are "snapped in".

 

You could try a little dielectric grease on the ends of the wires to seal them off from the moisture.It also helps to "click" the wires on over the ends of thespark plug boot.

 

I figured it out it was the chrome covers for the head bolts and plugs, the plug was only sticking through about 1/2 inch was not enough to be covered by the boots, sprayed the boot ends on the plugs shut the lights off in the shop and the sprks were flying everywhere around the plugs, so i removed the covers drilled out the plug hole replaced the wire so they slide threw the plugs covers instead of stopping against the top and no more problems, just wanted to let u guys know
