Thread: P0178 code

My car keeps getting a code p0178, bank one rich. I only get code while driving the car while its not up to operating temp. It comes on when temp gauge is almost up to temp. The code comes on a few times a week. I'm guessing it's something to do with open and closed loop. Also it never had the code before i put a o2 sensor in it. Any help with this would be appreciated :-)

Its a bosch o2, i agree cheaper parts tend to have problems. I might try another o2.
