Did it happen right after the TB swap? Try putting the old one back in and see what happens first.

First off, the CTP switch is definitely not working, disconnected, out of adjustment, or the throttle actually isn't closed all the way. If the CTP tells the ECU that the throttle is closed then it will cut fuel (or spark??) at around 2000rpm and that'll give it that surge that a lot of DSM's have. Try disconnecting the throttle cable from the t-body to eliminate it being out of adjustment as a possible cause.

Make sure you put the gasket on the right way too or youll have a leak.

Good point. I totally forgot about that even though it bit me in the ass once. The stuff about the CTP still stands true though, even with a air leak like that.
