View Full Version : DTC P0172 has shown up

Filled tank with Mobil early in the week then brought the car home and parked due to our recent lovely weather. Finally got out in it last night and DTC P0172 (Rich Bank 1) kept setting while driving. I have read the manual on this code and am wondering if the fuel tables need to be tweaked. It is only bank 1, but with the slight differences that can exist in injectors it might be only bank 1 that has exceeded the threshold. Car has a custom tune and has run fine to this point in time.

Has anyone else slayed this dragon?
