Thank you guys for trying to help everyone. Ok, I have a 2002 nissan altima (2.5 4 cylinder) and the check engine light recently came on. I also noticed that I was burning up ALOT of fuel and also only one of my exhaust pipes was blowing air out of it. The other was was blowing out air at a minimal. Nissan changed the cat converter but I still noticed that the air is still only coming out of one exhaust pipe much more than the other. Did nissan really change the cat converter? Or is this even a problem....Thanks.
