Question
my first 02 censor is out and im starting to develope a loud
noise under my front wheels when i start the car-what causes
this?

Answer
Marliquea, i think i just answered another question earlier for you! The noise could be that the exhaust and O2 sensor being out are the cause. Almost like a backfire. Nothing to be worried about for now but not fixing the O2 sensor can damage your Bank 2 O2 sensor and the catalytic converter or other exhaust components. Fix it ASAP!
