there are 2 vaccum hoses going into the intake. the larger one on top has a spring clip holding it and if you look under that you'll see a smaller one with a check valve. mine was disconnected. plugs in under the larger one.

I am not familiar with Cabrios. I am very familiar with VW Passats and Audis (VWs in disquise) . Please read my experience with my 1997 VW Passat VR6. Since your Cabrio is a VW, it may have a very similar problem.
I had a similar problem to yours with my '97 Passat. Bank One Failed was the code I observed. To fix it, I removed the throttle body from the engine by disconnecting the air intake, two small diameter water hoses and one or two electrical plugs.
The throttle body (sounds complicated but it isn't at all) was dirty. I removed the four Torx machine screws which attach the throttle body to the engine and put the throttle body in my wife's largest stainless steel mixing bowl. I bought a large spray can of "Throttle Body Cleaner" and a cheap toothbrush. Next I spent about an hour scrubbing a thin layer of carbon deposits from the throttle body. I had to use my thumb to hold the throttle door (not a technical term :-) open and sprayed/scrubbed/sprayed/scrubbed until everything, even the very edge of the little metal throttle door, was all shiny and clean. When I was all finished with cleaning the throttle, curiosity got the best of me. I fearfully removed the cover from the electronic throttle control mechanism to see what it looked like inside. After taking a long look at it's inner workings, I carefully and reverently replaced the cover and prayed to God I hadn't disturbed anything by breathing on it. That gizmo is REALLY complicated! Some piece of German engineering.
I replaced the throttle body on the engine. I reconnected everything as it had been before. Total time less than three hours.
Next, used a trick known to sage VW Gurus around the world.
You see, whenever you
1. Replace your VW battery
2. Mess with your throttle body
...you MUST perform a "THROTTLE ADAPTION PROCEDURE"
This sounds (and is) tricky and complicated. I didn't want to do a throttle adaption procedure because I was sure I would mess it up.
I got really lucky and found a friend of a friend who is an experienced VW mechanic. He let me in on a little secret.
John said "Buddy...
==>disconnect the VW battery for forty-two minutes."
"When you reconnect the battery, the computer chip will return your throttle settings to factory presets."
Woo Hoo! I disconnected the Passat's battery. I set the timer on my oven for forty-two minutes. When the oven timer went off, I reconnected the battery. I connected my laptop's serial port to the OBD computer port in the Passat's passenger compartment and used my Ross-Tech VCDS software to clear all of the OBD codes. Then I performed another scan. The Bank One Fail code did not re-appear!
My Passat has idled smoothly ever since!
Kimberly, I know it is hard to believe that a thin layer of carbon deposits would have such a profound effect a VW engine's idle. Apparently, this is the case. The throttle door was being held slightly open by the accumulated carbon deposits. The throttle position is so very sensitive that it caused the engine to log
the BANK ONE FAIL code.
I hope this helps you. By the way, I went to Sears hardware department and purchased the Torx socket required to remove the throttle body.

Basically this means that an oxygen sensor in banks 1 and 2 detected a rich condition (too little oxygen in the exhaust).
A code P0172 may mean that one or more of the following has happened:
· The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters can cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
· There could be a vacuum leak
· There could be a fuel pressure or delivery problem
Possible solutions include:
Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling

There may be problem with the mass air flow sensor (very common with Volvo). This causes the fuel system to malfunction.
You may have noticed increased fuel consumption, loss of power and general 'lazyness'.
Better to take it to authorized Volvo service for a checkup/fix.
