The idle RPM still fluctuates here a little bit from time to time AFTER the CEL fix. But it never feels like its going to stall because the ECU corrects the situation quickly.
I always have the blower fan running though (foggy windows) and I know that puts some load on the engine.

I'm starting to believe it's just a feature of the engine management system.
It's too common to be an isolated issue. Just look at the number of reports in this forum alone..

I just got my first oil change done and also got better quality gas than what I usually get locally. I'm going to check if anything changes.
