    LOL - however I don't see anything that points to a fuel system restriction, as that would be a more consistant problem.

    What I am describing / experiencing happens only under very specific circumstances - i.e. heavy load + pulling hills + outside temps >75F.

    Its definately fuel temp related, unless 180-190F fuel temps are considered normal...
