Engine Skip During rain

[zippymedic]

I've read the post for replacing plugs, wires and coil packs for engine skip. The 1997 v6 runs great during dry conditions. As soon as I pull into a car wash and the undercarriage wash starts, instantly it skips and runs very rough. To much snow outside to change the plugs or check for a problem. Just wondering what I should tell the mechanic to change first at the garage when I take it in. ??Plugs and wires??? Coilpacks?????? Are these expensive???? Should I replace everything at once???

you shouldnt have to tell him to replace anything. he should tell you what needs to be replaced. thats his job. if hes a good mechanic, hopefully he wont spend as much of you money as you would search for a problem.

sounds like the place the coil packs sit is getting wet

yeah, it seems like the electricity for the spark plug is conducting somewhere else when theres water near it. I'm guessing theres a crack in the spark plug wires somewhere. Check the spark plug wires especially the part that is close to the manifold.

My last car had a crack in one of the spark plug wires and it did the same thing. One night I popped the hood while it was running bad, and actually saw the sparking. That made my diagnoses easy.
