Upstream O2 sensor removal

Recommended Posts

I did some searching, but couldn't find what I was looking for. Does anyone know of a good way of removing the upstream O2 sensor? It is pretty tight in there. A regular 7/8" wrench fits, but there is barely any room to turn. Figured someone here had something bookmarked. 😉

i have both of these...can't remember which worked out better for the upstream sensor...on top of that i think i took a few parts out from the top of the engine (plastic intake) and just used a bunch of ratchet extensions to get down there...or maybe that was for the downstream sensor...can't remember...
