hay guys i recently purchased an oxygen sensor for my 91 california esv supra( was told faulty o2 sensor simulates an exhaust leak- also geting mixture continusly lean diagnostic code ) and was looking for tips on installing the part

why would you remove seats for an O2 sensor...

The oxygen sensors are on the exhaust. On non turbos you can see it from the engine bay, turbos they might have 2 probably under side also. I have not really looked but the non turbos might have 2 also. But no matter what they will be on the exhaust on almost any car. Someone probably was confused about a fuel pump, on many cars like eclipse, and Hondas you do have to remove the back seat, and carpet to get to the fuel pump, they just miss understood the question probably.
