what do i do

[teh_milz]

my car is running like poop. if i give it about half throttle it does just fine but if i punch it it just stubles like crazy. from a stop if i punch it it stubbles then goes but doesnt have any power at all. check engine light is on but reads only o2 sensor 1 in bank two. where is bank two sensor one? and could that make my car run so bad?

Yes, it very well can. Seems to be prety common with these things. Im unsure which bank is on which side, but sensor one is right off the manifold, and sensor 2 is in the side of the catalytic converter. There are four O2 sensors in all, two on each side of the exhaust. All have to be acessed from below the car.

bank 1 = where cylinder 1 is = passenger side
sensor 1 = before cat

someone correct me if I am wrong.
