I wasn't expecting such a dramatic result. After I removed the rack damper bolt I screwed the lock nut all the way against the adjustment nut and put it pack in the IP. That was the hardest part of the whole job since I already had the engine up to running temp. That oil filter housing gets HOT! ... plus I could only blindly use the tips of two fingers to try and maneuver it back in and get it to catch on the first few threads.
As I screwed the bolt back in half a turn at a time, since I needed to flip the wrench over to be able to grab the bolt at every half turn, the idle suddenly went from sputtering to smooth. I could loosen the bolt a quarter turn and it would sputter again, and then tighten it a quarter turn and it would get smooth. If I tightened the bolt too far, the car would smoke.
I played with that a few times, then locked down the nut.
I tested it in drive and park, and it was perfect.
The idle adjustment screw was frozen so a little squirt with Aerokroil and it turned with ease. I did the idle adjustment with the car in drive and the E-brake cranked down with ramps in front of the car.
