Is it carb or FI? If carb, it sounds like accellerator(sp?) pump.
1979 Fiat Spider (since new)
2005 Lincoln LS (the wife's car)
2003 Chevrolet Cavalier (daily driver)
1999 Honda Shadow VLX 600

When you open the trottle plate (push down your gas pedal) you're allowing more air into the intake. This causes the flap in the AFM to open more which is read by the ECU as a demand for more fuel. Your flap may be sticking. Remove the boot at the AFM and reach in and move the flap, checking for smooth operation, try to move it the whole arc of travel.
