i'm interpreting:
when the engine load was 68.2%, short term trims were -1.6 and -3.1.
i'm not sure what you mean when you say the 'breakdown' was 0% bank 1 sensor 1, 99.2% bank 1 sensor 2. i'm not sure what the percentage readings you're providing me for the o2 sensors mean.

I'm not sure what the percentage readings are. They are listed as fuel trim readings and not listed as O2 sensors.

I will check again for vacuum leaks. I don't think that's the issue this time since the problem goes away immediately when I clear the codes. I'll clean the IACV too and make sure there is nothing freaky going on with that. I'll post the results as soon as I get to these. I'm working on the clutch in the 928 today so we have two cars running again.
Thanks!
