ok started hesitating or stumbling once in awhile i changer the plugs, wires and fuel filter, still stumbled when it warmed up so i changed both coils and it sumbles all the time but if light on the gas pedal its fine i have no check engine light on and no codes come up on my scanner at a loss i have changed everything i can think of any ideas?

Check the throttle position sensor. (TPS) A scan tool is required for checking the operation of the TPS.
