  1. Hello everyone. I've had these two faults appear three separate times now, all within about 100 miles of each other, and all when the car has been idling for a short period. P0172: System too Rich (Bank 1) P0175: System too Rich (Bank 2) I've searched the forums, and it seems the likely cause is the MAF, but I wanted to post my Torque Pro logs of when the CEL occurred to see if any of you could help me pinpoint the problem. For what it's worth, I just changed my spark plugs last weekend (after having seen the CEL twice) and inspected the ignition coils, but no problems were found and the CEL appeared again this morning. My MAF looks clean to the eye, but I'm hesitant to use electrical contact (no residue) cleaner on it unless it's absolutely necessary. The first Torque Pro log below is from just before the CEL occurred when I pulled up to a stoplight. The second log is from a few seconds after the CEL occurred as I was pulling away from the stoplight. Log #1: Pre-CEL Time: 04-Apr-2012 09:02:15.096 Speed: 0.979mph Bearing: 341.0 G(calibrated): 0.00141555 Fuel Trim Bank 1 Short Term(%): 0 Fuel Trim Bank 2 Short Term(%): -1.5625 Fuel Trim Bank 1 Long Term(%): 0 Fuel Trim Bank 2 Long Term(%): -0.78125 Engine Coolant Temperature(°F): 184.99999595 Engine Load(%): 2.35294127 Engine RPM(rpm): 691 Mass Air Flow Rate(g/s): 6.25 Throttle Position(Manifold)(%): 2.35294127 Fuel used (trip)(gal): 0 GPS vs OBD Speed difference(mph): 0.35807136 Transmission Temperature(Method 3)(°F): 184.99999595 Acceleration Sensor(Total)(g): -0.01302952 Acceleration Sensor(X axis)(g): 0.00555366 Acceleration Sensor(Y axis)(g): -0.03887559 Acceleration Sensor(Z axis)(g): 0.01943775 Log #2: Post-CEL Time: 04-Apr-2012 09:03:56.093 Speed: 5.597mph Bearing: 2.0 G(calibrated): 0.06632715 Fuel Trim Bank 1 Short Term(%): -3.125 Fuel Trim Bank 2 Short Term(%): -7.8125 Fuel Trim Bank 1 Long Term(%): 0 Fuel Trim Bank 2 Long Term(%): -0.78125 Engine Coolant Temperature(°F): 197.59999561 Engine Load(%): 10.1960783 Engine RPM(rpm): 823.5 Mass Air Flow Rate(g/s): 9.75 Throttle Position(Manifold)(%): 14.11764717 Fuel used (trip)(gal): 0 GPS vs OBD Speed difference(mph): 0.62137121 Transmission Temperature(Method 3)(°F): 197.59999561 Acceleration Sensor(Total)(g): 0.03373463 Acceleration Sensor(X axis)(g): 0.17216341 Acceleration Sensor(Y axis)(g): -0.31378168 Acceleration Sensor(Z axis)(g): 0.13189937 Thanks for any help you all can provide!
