    hi joe.
    im not sure if you changed the spark plugs or not but that might work.  spark plugs get hot and will burn fuel different,  you could have some carbon build up on the plugs and its only burning enough fuel to reach certain speeds..  also try changing out your antfreeze and your thermostate to keep things cool..
