Changing plugs, kill 4x4???
Hey guys and gals I was just wondering if there is any possible vacume lines, switchs, electrical connections in the area of the engine needed to access the spark plugs. Last weekend I put iridium plugs in my 4.0L SOHC and I know have a problem with my 4x4. I am close to taking it to a dealer and just thought I would present this quick to the forum.
