Default check engine light
someone told me if the check engine light is on, it affects your gas mileage and your car's performance is this true.

if your light is on because you don't have cats then its not hurting your gas mileages/performance like a bad o2 sensor would. easy fix would be to order some MIL's. check out mustangtuning.com.

they plug into the rear 02 sensor connections and fool the computer to think you still have working cats, if they are good that is
