Hello everyone
Has anyone ever had the P401 EGR recirculate insufficient flow code come up?
I have a 13/14. the light has never came on and I have 15k miles on the car. I put an O/R X pipe on over the winter and the light stayed off along with the O2 sensors went ready. One weekend i decided to run 5 gallons of C16 leaded fuel in with about 5 gallons of 93 for a dyno day. After that day the P401 code keeps coming up. I put the stock H pipe with cats back on and went back to 93 octane but the light keeps coming on. Any help would be great.
