You know, I would be curious. Take it in to a AutoZone, Shucks, whatever you have locally. They normally will plug in and scan for free hoping they can sell you something. Ever since I installed the Morgan Tec cold air induction, I have been getting the CEL and my scan gauge shows a P0113. I don't have the sheet handy, but that is air inlet temp something or other. With the K&N like the Morgan Tec, you are passing more air, wait, that sounds like flatulence. Anyway, not sure if it is the same or what the fix is other then expensive troubleshooting. My mileage is in the ballpark and it seems to be running fine.
