So I am told there is one in the engine bay under the intake manifold.. Is the second O2 sensor by the front cat or by the one in middle?

depending on what state you or your car is from depends on how many O2 sensors you have... normally you will have two... a bank 1 and bank 2 O2 sensor... bank 1 reads cylinders 1-3 and bank 2 reads 4-6,... if you have ever looked at your exhaust manifold you will see its in two parts, both of them are high up on the exhaust manifold that you can easily reach from the top... if your car is from cailifornia you will have a third O2 sensor called the sub O2 sensor that you can get to from under the car just before the second cat... use the search button you can find all this info that has been talked about several times over
