Mine just turned 105k. After changing the plugs and putting the old O2 sensors in, I ran it up from NC to OH and got 16 mpg. My CEL came back on with the P0430 code (Bank 2 Cat below threshold). I'm hoping that replacing my cats/exhaust system to high flow will help it even more. I also will have my new K&N Cold Air Intake waiting on my porch.
