Cleaned it with some motormaster throttle body cleaner, pretty good stuff, haha
as for DIY, I only snapped a couple of pictures so it would be difficult to show, but the TSB (P2070) itself is a pretty good TSB and the instructions and diagrams were pretty easy to follow.

YEAH!! Glad it's fixed and that you didn't have to spend $$$ to have the dealership take out your engine.

+1 for DIY know how

 

it seems the injectors come before the SSV valve, so technically couldn't running some carbon cleaner in the gas tank help clean it off and prevent deposits from forming?

 

Cool, I must've missed that TSB, never saw it before. If I get P2070 again, I'll try bringing it in and see if they will warranty it.

 

The injectors come after the SSV, not so sure about the Aux port tho.
This is a pretty good animation/video, shows how those valves actually open.
