something is wrong then. I can spin the {stock size} tires with 1/2 throttle from a dead stop, no power braking involved.

Yep... the fuel pump is a likely culprit. I'd replace it ASAP before it toasts the control unit.

If its buzzing that means its going bad. Replace it. It is one of the cheaper repairs on this car. Get the O-ring and don't mess it up. Might as well replace the fuel and air filters if they haven't been changed recently.
