Default Re: Disable EGR Valve?

EGR stabilizes combustion by mixing in a little bit of inert exhaust gas at high temps. If an engine is configured with it, disabling it without adjusting the air fuel mixture will give the engine a higher tendency to misfiring. But then your messing with damaging the cats.
