Coming home from a trip engine started to misfire. come to find out the # 3 spark plus exploded destroying the coil and and threads holding the spark plug in. causing the need to re tap the threads.

We were driving down the highway at approximately 70mph, when i heard a loud pop and clanking noise on the driver's side front engine area. i was driving with my whole family in the suv. we were able to still drive it to a mechanic. the mechanic diagnosed it as a "blown-out spark plug". he said the spark plug had come out of the engine block. he said it is a common problem on that engine and there was a spark plug kit for it. he used the kit, and it only held for about 2 months. it now has lost power, shakes, and poor gas mileage. the repair kit obviously is not ample for this problem. *tr
