    Just had the tsb done. Seems to have more consistent power. Unfortunately It did not cure the “STALL BUG” as hoped. I stalled literally on the way home from dealer.

    Is the stall bug you are experiencing like the one I am? Twice (on two different days) while climbing a mountain pass in Colorado the vehicle shut off, the dash lights came on, and then the engine came back to life like nothing happened. I have not taken it in to the dealer yet.
