Is this forum still alive?!

I've already stumped two mechanics with my ongoing dramas (1 year anniversary, yay), now it's at a Holden svc ctr and they are already making noises like they really don't want to deal with it.

The short story is that I'm getting a P0638 "powertrain throttle actuator controller" error. Happy to go into more detail about the history of the fault etc if there are any takers...?
