I wouldn't bother with th O2 sensor. Last time I adjusted the A/F on my car was in 2004, and based on the three smog checks since then it's running cleaner with every check, though the differences are minute. I don't think you have to worry about it drifting, unless you didn't clean everything up thoroughly which would account for some change over time.

did you take the pressure regulator out of the fuel distributor? if you did you must not loose the shims like i did .even by disturbing the regulator it may need to be re shimed for correct system pressure.
