Okay i have an update that may help describe further. Every time i start my jeep from a cold start and go to drive off, the jeep hesitates when i push the accelerator, and its almost like i can hear each cylinder firing or exhausting one or another. Sometimes while driving i can feel the engine go under strain then go to normal then go under strain then go to normal im not sure how else to explain that i can just feel the differnt vibrations in my feet, this only happens at a constant speed that i can find. Then also im thinking it could be out of timing, when the engine is idling i can stand behind it and listen to the exhaust and it sounds pretty nasty and about every 3 seconds i hear a misfire maybe or something fired to late, and also everytime that happens it looks like carbon comes out and i can see it all over the concrete. Another problem im having is that sometimes the jeep will have alot of power. And other days it will have barley any, almost to where i have to be WOT to keep up with traffic. Sorry that this post is kina un-organized. im very frustrated because ive been driving it like this for 10 thousand miles and it does it 85% of the time im driving... But thanks for taking time to read this and i hope i get some more ideas!
