Second that on the wire, had the plug fall off my trooper at 70mph, left brown spots on the seat, I shut it off and coasted to the shoulder, popped the hood and did a check, instant relief when I saw that plug hanging loose there. Tense 2 minutes for sure... then 10 minutes later the #1 plug blew out of the head, that was the LAST time I EVER let a dealer under the hood....all the plugs were loose.
