- Hey Scotty, I have a 2014 Toyota Corolla S 4cyl 1.8L 166,000 miles automatic transmission
I had some intermittent stalling and rough idling at red lights. Others suggested using maf cleaner which I did. The mil says p0171 and p0219a for the oxygen sensor bank 1. Doesn’t say if it’s upstream or downstream
What should I do you think?

I would replace the fuel injectors. Check also the PCV valve and fuel pressure.

I have a 09 corolla with a p0031 oxygen sensor heater control circuit low. I have a exhaust leak which is causing it to idle inconsistently mostly in park. So that could be what your problem is only if your car is loud or smells smells very bad.
