hesitation

Do you have a check engine light On and last tune-up??

Could be caused by one of the following below

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it and keep testing.

no I have no lights on at all. it just started about 2 weeks ago when I first noticed it. I was out of town and the car drove fine and then I came to stop sign and then when I proceded to take off it didn't want to go but after it came up to speed it was fine all the way home but when i leave in the mornings i let the car warm up and its fine but when i get off in the afternoons i let it warm up some then it happens again when i go to take off then its fine maybe i'm not letting it warm up in the afternoon but i was told i don't have to let it warm up not sure of the problem someone told me to change the ATF fluid not sure if thats correct or how to do this

Check the intake boot for rips.
