I could probably use a rebuild on my throttle body also, but my solution was to restrict the PCV hose back to the plenum. I y-ed the hose circuit to a filtered can so the PCV can still flow out in volume during hard accel. But it did drop the rpm's 100 or so at idle and got some positive IAC counts.

seems to be a common thing on these engines.
