Wet spark plug A wet spark plug means the plug has not been firing. If not due to engine flooding, the problem may be a bad ignition cable (excessive resistance, shorted or arcing). But wet fouling can also be caused by dirt or moisture on the outside of the plug that provides a conductive path to ground, or by an internal crack in the ceramic insulator that shorts the plug to ground...try a set of plugs 2 steps hotter ..
Hmmm. New plugs, wires, cap, rotor, coil, injectors, IAC, TPS,... Maybe another explanation??
Or perhaps you could recommend a hotter plug Part Number?
