Woody, Never got an answer to my last PM... Figured you were busy... Re-learn and your carsoft to see if the fuel / timing will re-adjust... ???

PS: just looking at the 1/1, 1/2, 2/1, 2/2 02 sensors and the wiring schematics from the manual... On the sensors there are 2-wht, 1-gry, 1-blk... This does not correlate with the connector diagram in the manual (not surprising) I'm looking to tap the signal back to the ECU on the sensor itself, instead of after the connector... I'm going to try a adjustable voltage clamp to see what it does...
