Thanks guys and thanks Offroad4x4, yes for the most part I would say it was a city rig. It does have 220k miles and I bought it from a doctor that was the original owner, had very small street tires and had never been used offroad or anywhere off the asphault. I think he took "okay" care of it but it had plenty of bad parts like plugs, distributor, etc. .When i bought it, it was running rough at start and then ran fine after warming up, I've changed the plugs, distributor, rotor, AFM, PCV, vacuum hoses, fuel pump, fuel filter, cleaned the throttle body and the cold start injector. It does run very good now and I found a main vacuum hose that was disconnected which fixed the idle and initial rough running problem. He did have lots and lots of receipts for work he had done on it over the years, including having all the gaskets and seals replaced in the past couple of years so it doesn't leak any fluids.
Yesterday while working on the rear bumper I noticed the buildup in the tail pipe, it seems to be very thick, probably 1/8" of just black carbon CRAP, I scraped some out with just my finger and there was plenty of it, I'm not so worried about getting the exhaust pipe cleaned but more of fixing the problem of putting out that kind of carbon residue.
I know I need to do the high octane gas and I currently have seafoam in the gas but the only running it has gotten is at my house because I've been working on the engine every since I bought it. It probably needs to just be "RAN" kinda hard to blow some stuff out.
