Ok I'm posting b/c my hubby doesn't like to but he is a great mechanic & electrician so I'm confident he can remedy the problem. We just need to pin point the problem.

So when going thru an undercarriage wash or raining it runs real rough. He keeps up maintenance very well. My D has a cold air intake, Bosch Plus plugs, & KN filter.

Any words of wisdom to help us?
