If your car hesitates when the brakes are applied, and or when you are driving it acts like it is giving itself gas, or accelarating on its own, The problem is your Throttle Position Sensor(TPS). It costs about $34.00 at autozone, and only takes about 10minutes to replace. sounds like you need a tune up. could possible be fuel filter or fuel pump. sounds like you need to replace fuel filter, air cleaner, and maybe a tune up

A leak in the brake booster is one common reason why a car would stall or hesitate when the brakes are pushed. There could also be an obstruction in the brake line.

Bad speed sensors can cause the car to hesitate when accelerating at speeds below 20 mph. The blockage of the air filters can also cause the car to hesitate when accelerating at speeds below 20 mph.
