    reading spark plugs

    hello again Gentlemen,
    I pulled the plugs just to check whats going on in there, and checked with the NGK web site. #1 is definatly rich, #2 and #3 look like the "Dry fouling" picture on the site. #4 is dead on where it should be. What causes dry fouling? Acording to the site it has something to do with plug wires. How do i test and fix whatever is causing this?

    Thanks again!
    Tony

          Plug wires

          Are solid core on the stock coils.
          The plug cap screws on and is a resistor cap.
          Not unusual for the end of the plug wire to get some corrosion which you can trim off 1/4 to 1/2 inch, clean the cap and screw it back on.
