1996 Chevy Camaro O2 sensor

I wanted to know how to replace the bank 1 sensor 2 in this car. Having troubles locating it in my handbook. This is my first o2 sensor so im having troubles. I had problems with it miss firing so I replace all coils and now it is not miss firing. The car is still shaking a bit and the service engine light came on. I had that checked and it says it is that o2 sensor but it is "pending" that is what the computer test says. Can you give some advice and also tell me how and where to find it so it may be replaced. Also it had been a week after I replaced the coils that the light came on. I need this taken care of asap so I may register my car, and have the inspection done on it to do that. Thank you.
