VW 4 cylinder engine with distributor.
Hall Effect sensor with 4 window wheel in distributor used for triggering.
Distributor used for ignition, Stepper A to single Ignitior/Coil.
The issue is: The RPM value drops very low every few seconds.
Tried using 5volt and 12volt supply for the Hall Sensor, same results.
