|All right, I will look into that. So after a bit of driving it seems that the problem is brought on during WOT. If I accelerate gently through the power band it goes strong and steady. If I mash the gas pedal or if the car is under load (again, more pedal) I get my power loss. Does this shed any light?|
Maybe, maybe not. If the O2 sensor is not working or the ECU is not seeing it, nothing is working right and we cant even verify the idle CO current is right and everything "fuel" depends on that to be right.
Since the 19.7ma you see when the engine is warmed up doesnt appear to fluxuate and that is the normal behavior if the O2 sensor is shorted, I would address that first and see what other symptoms remain or change.
My approach would be to monitor the O2 sensor output with its sensor lead disconnected from the cars harness usinf a DVM while running the engine and see how it behaves.
I would watch it at idle with everything warmed up and adjust the CO screw a little to see that it indicates rich (above .5V) and lean (below .5V). (If that works, leave the CO adjustment where the O2 sensor says .5-.6V.) Then open the throttle some and see that the voltage changes. From there I would proceed depending on the results.
