sticky caliper or... try changing the fuel filter.

Has nothing to do with the fuel system

i'm guessing u have full rpm's then.. sticky caliper not returning or torque converter not disengaging... need more info to really get a better idea really.

Check your exhaust pipes while idling to determine if there is free passage..maybe you catalytic converter is stopped up..

If you feel it is a sticking caliper, start in the back and jack up a wheel and try to spin it...while still up, push the brake pedal hard then try to spin it. In the front it would work best if you could get both wheels off the ground and try the same above. It seems like that most of the "sticking calipers" are caused by a failed flex line going to the caliper.. These lines have a plastic inner line, then rubber/plastic around that to protect the line then the outer covering. Quite often the inner plastic line crack and depending on how it cracks, it can act as a one-way or check valve...when you push on the pedal, there is enough pressure to push fluid past these problems (most of the time) but when you release the pedal there is little pressure to return the fluid past the restriction so the piston does not retract immediately and sometime not at all. One problem is you cannot see these failures, but testing the wheels by turning them gives you a clue to which wheel to start.
