What could cause this?

When I tap the throttle in park the car will act like I hit the throttle twice. The car also has a hard to notice miss at Idle and at light throttle. I am going to try the fuel filter tomorrow; the car is drinking the gas, 9mpg on the streets and 20mpg on the highway. I don't have a problem with the highway mpg but I think my Idle and low end problem is causing the car to run rich and drink the gas. I do not notice a problem at highway speeds at about 2500rpms.
