engine help

well i noticed this today that my bottom crank pulley is kindda off balance(kindda wobbling,not much but a tiny bit)
and my tensioner pulley needs 2 ppl to move
what should i do,i dont want it to get bad.

oh and i ran my data pug tester and its giving me an O2 sensor code and low voltage,kinda clueless ,would that be the result of my check engine light from coming off and on sometimes(comes and goes)???

make sure it's not just an optical thing, like a paint spot or dirt or something so it looks like it wobbling. if you do have an outofkilter pulley, you should replace it.

yes. replace the O2 sensor, but first check the wiring.

I think he meant "out of kilter" or "off kilter" or "out of whack" or something similar!
