This is the 3rd time I'm receiving this code, I've already cleaned the throttle body and MAS, changed out my IAC valve, and already checked and found no vacuum leaks, is there anything else I should be looking for? When I changed the valve I had the computer relearn the idle (After the switch it would be in park idling at 2500 rpm, after the relearn it idles at around 900), but now I just got the same code and when I'm driving it gets to about 40mph and will rev up when trying shift. (usually shifted at 3500 rpm - 3800, now shifts at 4000 sometimes even 5000)

How did you check for vacuum leaks? A smoke machine? When you push in the clutch it jumps to 5000rpms and just sits there or will it continue to rev past that? Sounds like a massive vacuum leak after the throttle body. The sheet metal intakes are known to crack behind the throttle body flange (I've seen a few completely detach). Might want to start there.
