did you disconnect the battery and let the ECU reset adaptations after you changed or cleaned the TB? When I cleaned mine, it had a bunch of gunk on the back of the butterfly, and the computer was compensating the idle position for this, so when it was clean, then a lot more air was getting in and causing revs like this.
I would also try disconnecting the MAF as said above. This will cause the computer to go to sort of a default position with no input from the potentially faulty MAF.
