Thank you for the great input, this should keep me busy for awhile. I haven't had time to do alot yet. However, I did run some seafoam thru my vacuum/induction and barely got any smoke from the tailpipe. I did get almost as much smoke coming from where the pipe bolts to the end of the mAnifold. This among other things is giving me the feeling I have a problem with my catalytic converter, maybe it's clogged. Also after the engine is hot, and I turn it off, I've noticed a consistent ticking from the cat. So I banged on it a little (it's probably trash anyway) and from there the jeep ran perfect for about 100 miles. It seems obvious to me now to replace the cat??
