I have one of their throttle bodies also. I've been through a number of injectors, multiple IAC, and I'm pretty sure several TPS. But I need to get it on the logger when it is acting up. I know...

Thank you so much for following through with your solution. I have that same issue, though I'm sure I've swapped TPS's since it started. Still, I'll toss in a new one and keep this one as a spare.
