Abstract:
A method and system for controlling the engine during a return to idle maneuver when the engine's oil is highly aerated. The system and method will implement a stepped return to idle maneuver when the engine oil has a predetermined amount of aeration. The predetermined amount of aeration is an amount that could cause an engine to stall due to valve lift loss if the engine speed were reduced to the idle speed in the conventional manner.
