    My car has been stalling out for the past 5 days when i go down hill. It is a somewhat long and steep hill that is the main road into town. It starts in the exact same spot every time. The RPM's start to fluxuate and then stalls. Once i reach the buttom of the hill i start the car again in neutral while rolling and it runs fine. I have even tried to put car in neutral at top of hill and keep RPM's up with some throttle and it still stalls.

    This is the only place i have had this happen and it happens every time i go down the hill. It does not happen when i go up the same hill or any other hills.

    Anybody have and clues to this??

    At first I was going to say the fuel pump cant pick up the fuel, but doesnt seem to be a problem nowadays.

    Im kinda lost with you aswell, but I would take your throttle body off and clean it up real good if you havent already.

    I'm thinking broken baffles in the fuel tank.
