Thanks for your help. I'll give it a try and see how things turn out.

Hey Everyone, My 1994 GS300 Check Engine light is on and I took it in for diagnostics. The mechanic told me that the O2 Bank 1 Sensor 2 is bad. I have a couple of questions. 1. How many O2 sensors are on the car? I see one on the front exhaust manifold and apparently there is one after the catalyst. Is there also one directly in front of the catalyst as well? 2. Which sensor is Bank 1 Senosr 2? Thanks for your help!!!
