Message Profile is accurate. 740cc injectors all 4 ohm at 11.4, 1 at 11.3 and one at 11.5. Spark plugs look good.
At idle when the A/F ratio on the AVC-R changes, you can hear a change in engine sounds. Like the RPM fluctuates a little, engine tone changes some and A/F changes. It's odd, hard to describe. And it isn't necessarily consistent. Sometimes it maxes out at 20, then may drop to 13 or down to 11 (on the AFR). I wouldn't worry too much but the fuel smell in the oil worries me. I was almost hoping for a pinched o-ring, but the air leak test under water ruled that out. Driving around it indicates about 14.5.

Conversation between my sister and my wife (shortly before we
got married):
Wife: "You know, sometimes I think he loves that Z more than he
does me."
Sister: "He probably does, and as long as you're okay with that,
everything will be fine."
