It has a fast start feature that keeps the idle high until it warms up to 130 degrees i think then it returns to proper idle range, usually between 700-800 rpm. All cylinders should be firing when at idle and during fast start.

All cylinders operate all the time. However, when you shift from gear to neutral, 3 cylinders lose spark for a second to assist with shifting.
