But I have never seen any codes thrown relating to the O2. What is the correction to this?? Shops here seem to have no clue regarding this issue. Is it downstream or upstream??? The one at the header or after the cat??
The engine is just 097394 miles. Probably my air filter is dirty??

the front sensor is called sensor 1,  front, or upstream.   it controls fuel mixture.
the rear sensor called sensor 2, or rear or down stream or rear cat sensor has nothing to do with fuel mixture, it only does the CAT tests. all cars 96 , up , petrol or gasoline.

on all machines you can only do 3 things, do tests, guess or just ignore it.
your choice. 
my guess is that you drive it for such short distances the OBD2 monitors never fully run, to find the more advance checks failing.  like fuel trim , not right.

Thanks. What about the crack?? I have attached the pic?

that crack looks to ,me to only in the web, not into the tube, did you inspect the back side too with a mirror,  it must not leak air in to the exhaust ports .
but I'd never guess what is going on there, . only you can do the inspections.
does the CL closed loop only fail at idle,  try testing it at 2500 steady,,  even parked. hot.   scanning only at idle is not good enough.

Thank you very much for this. I used a touch, a mirror and even a magnifying device to have a look. On the back, it is more or less in the middle like the front picture. I tried to clean it and start the car to get it hot and dried in order to see it clearly. Are there any other ways to test it???

This is the picture of my Sport's current CAT https://imgur.com/cH13Ry5 The previous owner had changed it and I have just noticed it. I have no idea what is inside?? Does it have anything to do with the run rich engine??? Or make the car smell the burning gas at the back???

After cleaning the front crack https://imgur.com/r91X0Jx and the back crack looks a bit longer than the front https://imgur.com/6qSbIhO Anyway, where there is crack there is a leak. That is what I believe!!

Today the ecm has played on me!!https://imgur.com/jZjUCuc
