Hey! We are having all kinds of rough running problems with out 2001 Outback and it reads P0172 as well. We have a Digimoto OBDII that reads various parameters. Are there any other readings we can look at to diagnoce the problem? Also, what are the "adaptation values"? Any advice greatly appreciated! Cheers!

Hey everybody, great to join! This is our first post! Our 2001 Outback, 4 cylinder, has been very erratic. The pedal is unresponsive at times, and at other times the engine surges. Driving is very unpleasant at any speed and gear. Shifting to Neutral does not effect the engine surging. Using our Digimoto reader I got the following code: Category=Powertrain Name=P0172 Description=Fuel Trim too Rich (Bank 1) The TPS and O2 sensor are reading correctly. I have replaced the ignition coil pack and had the plugs and wires replaced. I have also run fuel injection cleaner and water removal additive in the last 4 tanks and no improvement. Now I am considering the fuel pump, fuel filter, fuel pressure regulator... Any advice is greatly appreciated! Cheers!
