Hello, new to the impala world. I’ve solved some other code issues I’ve had with the help of this forum but my last particular issue seems to stand out and not be found in the threads anywhere that I can find.
Anyways; currently I’m faced with a P0137 CEL for o2 Sensor bank 1 sensor 2 low voltage. And following symptoms are if the code is present, upon trying to accelerate the car will fall flat on its face for a few seconds then wake up and slam you into the back rest. And if the code has been present regardless if I’ve cleared it or not, when I key off the ignition. The engine will maintain rpm briefly and then cough and sputter like it ran out of fuel, but my thinking on this is that there’s still Excess fuel in the cylinders on shutdown due to this code. Also side Note I’ve had other fuel trim related codes intermittently if I leave this p0137 code on long enough. Such as p0172,p0175, p2097. Even had p0442 come up once.
Upon reading I’ve found that others have remedied this issue by replacing the post cat sensor for the “front” cat converter.
now I’ve got a replacement for that sensor but my question is. Could this code cause my issue of the engine stumbling to a halt when the key is switched off and cause my intermittent lack of power on acceleration also?
curious to hear anybody’s thoughts on this goofy issue......
