General Maintenance & Repairs - Exhaust Smells Like Alcohol?

i went to autozone im throwing the 2 front o2 sensor codes and i took the exhaust off to drop tranny and it smelt like pure alcohol i was like GOD! i didnt know what it was but it said the o2 sensors were bad would that make it to run rich and smell like that all i use is 91 octane no ethanol....

I think your car has been drinking...

Count your blessings and hook a still up to your exhaust!

O2 codes does not mean your sensors are "bad," they may be working properly and just be detecting a rich condition.

What are the exact codes?

Gas is now at least 15% alchohal - thanks to Congress...

which codes are you throwing?
