Title: maxed 02 sensor
Post by: larrym on December 09 2012, 02:18:07 PM

I am having a strange problem. My wide band shows a lean condition and the narrow band is maxed at 1047 according to the scan tool. It stumbles and is definitely lean. BLM is pulling fuel.
I've replaced the 02 sensor with a known good one and it still has the same problem.

Are you seeing cross counts?

no stuck at zero when I tip in the wide band jumps and it levels off. reset the computer and it purred but the o2s on the scan tool stayed at 1047 so it will start pulling fuel again

I think I figured it out there was water present in the connector at the ECU. Its drying as I type hope the ECU isn't hurt.......... .. might have to try FAST if its cooked
