So I apologize if this question has already been answered and Im just not using the write words to search. But lately my 08 JK has been acting a little weird. Randomly times throughout the day the jeep system just stops like it has a dead battery or something. The clock reset, or it won't turnover like I need a jump. Then I get out. Try again and it starts up just fine? Spark plugs going bad? Any advice would be appreciated!
