First, welcome to the site. Second, get some spray for the MAF sensor and spray it, it's prolly dirty. Other than that in a Chilton's, they have what everything means, I'm pretty sure.

BTW it has more than 1- O2 sensor.....lol and for the emmissions it could relate to a MANY number of things from transmission all the way to coolant temp sens. Mass airflow to Mapp or TPS sensor. REMEMBER this is a OBD2 CAR SO EVERYTHING ON IT RELATES TO EMMISSIONS. nEVER settle for the quick fix til you are SURE...then check again.
