I have had this ongoing issue with what appears to be my bank pre-cat o2 Sensor. I actually had this replaced 20k miles ago, but it is possible it could have been damaged again when the dealer replaced my turbos? or who knows.

2C3E:
2C3E Lambda probe in front of catalytic converter 2, control failure or cable transmission failure?
Error will cause a warning light

This will also be accompanied by mis-fires in my bank 2 cylinders 4-5-6. The interesting thing is when I re-cycle the car 1-2 times, everything runs fine until. This generally happens after the car has been driven for a long time and is very warm.

Car drives great at WOT, etc. Generally starts having rough idle at stop lights after the car is warm.

From other posts I have read, people just replace the pre cat bank 2 O2 sensor. I am tempted to have FFTEC replace my o2 when they swap my clutch out next wednesday.

Any other ideas?

I have new plugs, all my injectors are post recall and I am running a Procede 2.5 with the flexfuel kit.
