Tim, I don't have a clue about your trucks problem, but I did run across the other two plugs I told you I had! will send them shortly. Dave. P.S. never sand blast a plug and then put it back in the engine, its impossible to get all the grit out of the plug, it will come out later, guess where?? Dave.
