Slight stumble issue

[Tbolt]

Occasionally, but not all the time I will get a slight engine stumble when i initially lightly start to accelerate. Basically it is ONLY when I start to hit the pedal, once i press the pedal in more it catches up and is fine. This is a really minor thing, but its annoying as hell when I am leaving class and rolling up hill out of a parking lot. I figured I would ask here but I imagine this could be something to do with fuel injection? but why would it be find otherwise? maybe the ICV?

any/all advice is much appreciated.

Check to make sure the TPS is adjusted properly. It should click out of "on idle" position with the slightest movement of the throttle BLADE.
