PKP80 said:EGR is something like your Exhaust/emissions regulator. Mine got screwed up due to a custom intake I put on for a while (stupid idea). Smog time came and i replace the EGR as well as my stock intake. i definitely saw a different MPG wise in the short time I had my stock intake on while the EGR was still messed up.
