Your truck is a 2006, if the Pedal has never been changed, it's very probable that it's the problem.
You already determined it's not the ECU.
I would suggest to remove your Pedal and check it for side to side movement.
Unfortunately you need to do the process of elimination without throwing parts at it.
Without the ECU throwing a code, it's hard to determine what it could be until it gets worse or you replace the part.
