Must be. I fixed my exhaust leak, looked over all the wiring, and replaced the front o2 with a brand new denso. Cleared the code but it's still coming back. I tried searching the various forums for posts on this code and wasn't able to find much information. I would think there would be many more posts on this if it really was caused by the headers. I'm not sure where to go from here. Suggestions anyone?
