Well, they tossed me a response when I first went into the dealer to set up the appointment of, "Sounds like that problem you had last year. Check your plugs for moisture." So, thinking along that train of thought.... here we are.
So when I went in today, they asked me, what I had done already.
1) checked for moisture
2) electrical contact cleaner on the plugs & their wires
3) ran through a tank of fuel with conditioner to ensure no moisture in the fuel tank.
That just let him skip those steps this morning and focus on what the computer threw at him.
