If it's a V-6 engine the filter is located underneath the driver's side just inside where the frame is, on the 4 cylinder it's located under the intake manifold near the front of the engine.
there are 2 sensors in the system
one is a heated oxygen sensor (HO2S) in the exhaust manifold / pipe before the cat converter that reports the exhaust gas composition to the ECM so that fuel/ air ratios can be adjusted
if that one is faulty it is most likely the reason for running lean or rich
the second sensor is the oxygen sensor (O2) which is after the cat converter and reads the results of the cat converter cleaning the exhaust
you may have to replace both the sensors to get a clearance or replace the cat converter as well as the HO2S unit
Usually this is a bit of dirt in the engine plugging the oil port that supplies pressure to the variable valve timing control cam. Change your engine oil every 3000 miles and maybe switch brands. I had this problem on my Matrix until I switched to Castrol GTX 5W30 that cleaned the oil port right out.
