[QUOTE="radman, post: 373318, member: 167"] Cats have no effect on whether the engine runs rich or lean-they only deal with what is fed to them in the exhaust stream. They do offer a slight amount of restriction to flow (backpressure) which the engine management systems deal with, as do they deal with the removal of said restriction. The 02 sensor deals with off idle fuel mixture until WO throttle, when the ECM goes to full pulse on the injectors. [/QUOTE]
