Just a quick question after trying to search for it. theres a pretty big crack in the exhaust manifold where it all collects at the end which is pretty common from what i've heard. thats not my problem, i already have new ones waiting to go in when the weather gets warmer. But i am gettin 11-12 MPG city on a stock height 96 XJ 4.0 with 30" BFG A/T. Im just wondering if that could be causing an o2 sensor to be off and making my gas mileage suck. I'm not concerned about this, im just wondering.
