airflow isn't measured at the o2 sensors, but at the mas. your o2 sensors being fried should have nothing to do with it, still should be just sending the mas signal straight through to the computer. in fact, your o2 sensors don't ever send any info to the AFC, unless you did the blue-wire mod. and airflow is measured in karman's (hz). that 5v is your TPS thinking its at WOT for some reason.
like i said, get a volt meter and double check the TPS reading. you might have the afc wired into the wrong pins.
also, did you hook up both ground wires?

Wire connections:
POWER------------------------------red wire from SAFC======Pin 25; red wire at ecu
RPM SIGNAL-----------------------green wire from SAFC=====Pin 69; brown wire w/ green stripe at ecu
THROTTLE SIGNAL----------------gray wire from SAFC======Pin 64; green wire w/ white stripe at ecu
GROUND----------------------------brown wire from SAFC ====Pin 26; black wire at ecu
GROUND----------------------------black wire from SAFC =====Pin 26; black wire at ecu
The brown wire from the SAFC needs to be tapped closer to the ecu than the black wire from the SAFC!!!
AIR FLOW SIGNAL OUT-----------pink wire from SAFC======Pin 70; white wire w/ black stripe at ecu
AIR FLOW SIGNAL IN-------------orange wire from SAFC ====Pin 70; white wire w/ black stripe at ecu </div>
thats for the 7g. see how the two grounds need to be tapped. are yours the same way?
