Abstract
In a method of traction control, fuel injectors are selectively disabled to unfuel respective cylinders of an engine to reduce engine torque output. The method provides for limiting the number of cylinders that can be disabled for acceleration spin control based on engine and vehicle operating parameters to improve traction control performance and provide protection for the vehicle catalytic converter.
