Issue after replacing O2 Sensors
I have a 2017 Chevy Cruze Lt. My check
engine light had came on and off for a few
months with a code reading for bad upstream
O2 sensor. My car still drove fine. I finally had
the upstream O2 sensor replaced along with
the downstream as well since I had read it’s
best to go ahead and change them both out.
A couple days after they were replaced I
noticed the car stalling some(I have the stop-
go feature on this car) so when I stop at a red
light and the car goes off then back on, when I
press the gas to go it stalls a little...almost
feels like gas isn't being pushed through
correctly. The check engine light came on and
read for code P0172 which indicates that the
bank 1 system is too rich for a predetermined
period of time.
There is a note on the Autozone paper that
suggests the solution is to replace the PCV
tube.
Considering the the info of just replacing the
O2 sensors. Does anyone have any thoughts
on this or dealt with anything like this?
