Known-Good Waveform
This vehicle does not have a mass airflow sensor. The 1972 Dodge Challenger 400ci uses a points-type ignition system with carburetor fuel metering. Air/fuel mixture is determined mechanically by carburetor circuits responding to engine vacuum, throttle position, and atmospheric pressure through the carburetor float bowl vent.
