RE: HELP with check engine light
You need either MIL eliminators, or a tune that ignores 2nd set of O2 sensors complaining about faulty cats.
MPG going down is not a usual complaint. But the fact that you noticed it says you know your car in and out, good job. MPG goes down whenever smog equipement is faulty and ECU tries to compensate for it.
Now with cats off you can run richer mixtures without fear of burning them out.
