I got my 03 running great. It has good power and response all day long, untill you wash it. When it gets wet it barely wants to start after cranking for a few minutes, then when it does it won't run long at all.. even when it does run it don't have the power to move even in low. It acts like it's something with the plugs getting wet but I'm not sure if it's in the intake or if the plug its self gets wet on the outside and does it. What can I do to fix this? Is there something I can test?

 

Have you put any dielectric grease on the plug connectors? Check the wires for cracks too.
