Nice. I've never heard of that site. Very cool. I discovered another neat symptom my car is having and I snagged a log of it with torque. If I'm sitting still, and I try to hold the engine RPMs at a constant level by holding the gas pedal slightly, the revs constantly cycle up and down at a regular pace. Below is the log. You can clearly see the commanded AFR staying constant while the measured AFR, RPMs, and engine load cycle at regular intervals.

If more information would be useful, let me know and I'll take another log with the additional info.
Also I'll log some driving tomorrow on my way to work.
Thanks!
