help with P2195
 

I have a 2005 MPV, with about 70,000 miles.
the check engine light just came on and i have a rough idel when stopped ... runs fine at normal speed
took it to autozone and came up with codes P2195, P2197, P2177
i know the frist 2 have something to do with the O2 sensor, stuck on lean.. cant find out what the last one is.
not sure what i have to do to fix this.. do i replace all 4 o2 sesors and where the hell are they..
does anyone have any help with this, is there any pics i can see to find where these are at and what i have to do to fix this.
got a price on the sensor but its kind of high dont have that much right now.. is it ok to keep driving?
any help with this would be gratefull thank you
