| 1997 Porsche 911 Carrera 3.6L MIL Lamp on VIN: WPOCA2991V P1123: Fuel/Air mixture is so rich that the control is up to the lean limit. Vehicle appears to run very well. Oxygen sensors are very responsive to creating a vacuum leak as well as to adding propane. Not sure where to go next. It appears that it will be very difficult to test the fuel pressure, but i think that may be my next step. |
