Yeah, those spacers do nothing. Did you install new gaskets when you did all this?

All the stuff you did won't cause any problems provided it was done correctly. You probably have a vacuum leak somewhere now of the FITV on the bottom of the throttle body is leaking and that is why your idle surges. (Search for FITV if you need more)
