When i did mine I didn't think of the throttle body gasket...I bought one recently for about $4.00 just to have on hand in case I start pulling in unmetered air and want to change it out as it is only 4 bolts and disconnecting the throttle/cruise cable as well as unplugging the sensors.
Not having your idling problems but I recently had a check engine light indicating "lean under acceleration" and "bank 2 O2 sensor #2". I replaced the fuel filter first as it had 15k miles on it..didn't help.
Than I pulled my cone filter & cold air intake and reinstalled the factory airbox to choke off some air....didn't help.
Finally, I tried adjusting the fuel regulator by turning the security torx screw about 1/4 turn clockwise to go from lean to rich (as Tone mentioned) and it seemed to do the trick...about a week and no check engine light and I notice a bit better performance.
I bought a new fuel regulator in case I need to swap it out and in the process found out that you can buy a fuel regulator rebuild kit from dealer for about $12.....or buy the entire unit for about $52....as it turned out I have both! I figure I can swap out the original with the entire unit and rebuild the original for later use.
Also check the allan bolt that mounts the EGR bracket to the rear of the SC as if this comes loose you will get a vaccuum leak...mine could be snugged up a hair.
