    Just curious, are these Bosch or NTK WBO2 sensors, and are they the older 5-wire sensors or the newer 7-wire sensors?

    Danny, they are the 7-wire Bosch WBO2 sensors.

    OK, then you shouldn't be having problems with the latest EFI software & ECU firmware.

    Well, I found the definitive answer to the situation...battery voltage, LOL. At 11.8 volts and greater, both sensors light off quick and display A/F numbers quickly. At 11.7 volts, the left sensor comes on before the right, and only after a long wait. When it hits 11.6 volts, the right one gives the alarm "Slow!", with the red dot in the Data Monitor. Any voltage below that, and both sensors give the slow alarm. I found this out last night after messing with it, and both sensors looking DOA. I charged the battery because it was getting low, then both sensors worked fine.

    I thought it was firmware related because the sensors worked after I went back to the old, but I had charged the battery before flashing, so it just seemed like the firmware was the issue. If I let voltage fall to the levels discussed above, I can duplicate the WBO2 issue at will. I didn't know the WBO2s would give that alarm due to slightly low voltage, so just something to remember to check even though voltage is assumed to be sufficient. Just passing my findings along so maybe the info may help someone in the future. Thanks again Danny.
