First off just wanted to say hey to everyone. and welcoming me to the site. I was excited to finally a forum just for us NC folks.

Well, My rig I am driving is a 97 wrangler tj with the 2.5 4 cyl. (for a 4 banger it stands it ground). two weeks ago I got a new front o2 sensor put in it because the check engine light was on and I was getting 8-9 miles per gallon and my jeep reeked of exhaust because it was burning to much gas. Well two days ago my check engine light came back on and my gas mileage started to decrease again. But, i am not getting the smell of exhaust. im thinking it might be there rear o2 sensor but im not sure. so if any one else has had a similar problem please share so info with me on what it might be... thanks guys..
