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.
Some possibilities include: faulty or dirty MAF sensor, fuel pressure regulator, or the torque converer solenoid.
bad wheel bearings
Possibly a loose heat shield or other component.
