[s-cars] Running Rich: Help with Fault Code

Greetings, my car has been running rich of late. I had an oldish O2
sensor in there, so, I replaced with a universal (I didn't pull codes
before this). After 10 days, it is still acting the same way, so I
plugged in VAG-COM and got the following fault code:
00537 - Lambda (Oxygen Sensor) Regulation
11-10 - Control Limit Not Reached - Intermittent
So, a new (spliced) O2 sensor and this is there. Granted, it could be
left over from the previous O2 sensor; however, things are still rich.
The tailpipe is blackened and the plugs are sooty.
BTW, I have an RS2 setup with 37# injectors and MRC software. I am
also at altitude (Denver).
