Suddenly running very lean

[sinistrs2k]

Ya, I never did anything with the secondary sensor, havent touched it at all. I posted a calibration and datalog of it up above, but it didnt really show anything useful, just that the O2 sensor was reading lean and the ECU compensating until the car wouldnt run. If I hadn't had my wideband, I'd never have figured out what was going on.

I'll try to verify that there isn't a short in anything this weekend. I've got 5 months until I have to pass emissions, so no rush on this one ;)
