Hello everybody I need some advice on changing and gapping a new set of plugs. I recently just got a 2011 v6 and replaced the plugs last night with the Autolight iridium XP plugs. I did not gap them as I was reading through different threads were people said not to gap iridium plugs. The car this morning is being hesitant and not accelerating like it usually does although the fuel economy did go up. Does anybody have any recommendations on either gapping or a new set of plugs?
