Off acceleration stumbling

[2000Frontera]

Guys,

something that I have put up with for a while now, not a big issue, but I'll throw it out there and see if there is a simple explaination.
More so when the engine is cold (manual transmision) and your just rolling along at that on/off point of touching the accelerator pedal or even not touching it, the engine goes a little jerky like its minutely accelerating and deaccelerating by itself rather than holding a consistant state. Anyone have that occur? Bad throttle position senor?

Thanks

No. It's the 3.2L DOHC V6.
