Has the check engine light come on? Have any codes come up for the TPS or the IAC?

I would recheck your work and make sure there are no vacuum leaks. Also, check for fuel pressure to make sure the regulator is steady. FInally, have you heard any noise from the catylatic converter (ratteling, hissing...) I wounder if it is starting to plug.

Let me know what you find.
