The oxygen sensors are not difficult to replace. Since your car is OBDII I'm unsure how many oxygen sensors you have (2 or 3?). It should be easy enough to check, just look from the exhaust manifolds down for wires coming out. Mine only has one coming off the exhaust manifold, but it'* a 1992. I'm also EGR-less
A repair manual is a great investment if you're planning to do any sort of work to your car. A Chiltons can be had for $20 and ordered from any large bookstore.
