My uncle has a 02 mustang with the 3.8L v6. He knocked the guys out of his cats and is now getting a check engine light. I assume it is the rear o2 sensor. Can you resistor it to get rid of the light? If so what ohm resistor does it need?
Thanks,
gav
Go and get the codes read. It will more than likey be one that stated that it is over efficient and all.
The MIL eliminators are a device that plugs into the cat and the computer harness to trick the computer into believing that the car is running fine. They are used with O/R hpipes to get rid of the light.
