2009 chevrolet impala 3.5 flex fuel 180k miles
Hi scotty,
I have been working on a friend's car. It has a p0172 bank 1 rich condition code. I have changed Maf sensor, plugs and wires, tps with throttle body. O2 upstream sensor, air filter. It still has the same code. it's flex fuel could the alcohol content contribute to this code? Thoughts?
Thanks,
Chris

More specifically, the alcohol sensor. (or "virtual" sensor depending on model). You'll need a pro scan tool to diagnose.
