I have great heat up until my car runs down to idle speed stopping for a light or somthing like that then it goes cool. Anyone know why this happens? Which part to replace? I'm guessing one of the many water pumps is no good?

As a starter....it sounds like the pump that is on the pass side of the engine compartment on the strut tower with two (approx. 1 in.) hoses on it, it is the heater booster pump that runs all the time and designed to aid flow at idle, check for operation, power , fuse etc.
