91 accord: oxygen sensor location?
 
i need to change it, or at least clean it.
is it accesible from the engine compartment?

any tricks to taking it out?

You'll need an open ended wrench or an O2 sensor socket. It's right on the exhaust manifold. If you look down, between the radiator fans and the engine block, it's right there sticking out.

It's in the downpipe, shown as #27, pretty much where it joins from 2 into 1 pipe. Later years it's up in the manifold.

access from underneath then?

I never had a 91, but I guess it would be easier from underneath.
