The richer mixture was due to lack of voltage to the WUR, which is tapped off the rear pump circuit. Any fellow 930 owner, I need your help. I need to know if your car will run on either one of the two pumps. It's easy to check, just pull the red relays out one-at-a-time and see if it still runs. Please let me know.
