missing huh? you take the distro cap off and look inside (might have water in there especially after a good hosing), also check plug wire end boots for water. Brake clean spray is always good to blast them out with along with the plug ends. Ive always found that spreading around a little dielectric grease in the plug boots can help to seal out water\mud\blood\fecal matter or whatever else people like to drive through hope it helps
is that 2.5 gross with the DCONs? thanks for the review BTW always thought they look purty fierce...
