Really sucks though because gas mileage has been really affected. Anyone know what else to try?
I know some are pictures kind of people so I have attached the pictures of the old spark plugs as they looked funny to me.
(Hover over pictures for titles)
Left = Passenger Side, Furthest left plug is the plug closest to the front and go in order.
Right = Driver Side, Furthest right plug is the plug closest to the front and go in order.
