can my o2 sensor b throwin my idle off??

 

no.

 

didnt think so but i was told this and i figured id ask someone corn huffin hippie

 

oops i forgot to write 'besides a; sorry

 

o2 sensor wont effect the idle. unless its so rediculously off the engine is trying to overcorrect to lean/rich so much that it cant run right. but thats not propable... if you have obdII then you will get a code if your o2 is bad.
