Sorry couldnt really look up anything on here because i dont have much time due to the fact i am in iraq at the moment but the question i have to ask is that, What can i do to keep my truck from throwing spark plugs? When i was home on my 2 weeks leave it threw one for the second time and each time pretty expensive to replace. Any help would be greatfull because i return home soon and dont want to have to sell my truck over this...
