I was driving the other day and my CEL came on. I stopped at Autozone and it spat out code P0401 which has to do with EGR valve flow etc. I think it may have done this because I forgot to reset the ECU after upgrading my intake system, so I pulled the fuses and reset it and the car seems to be running fine. Should I be concerned that it threw a code, or was it simply my fault for not resetting the ECU after my performance upgrade?
