Hey guys, I have an 02 tj and just swapped a 4.0 into from an 05 into it. It’s been a nightmare getting everything to run. After 2 days of trying everything I could think of I got the engine to run but it’s running rough. It won’t idle but will run giving it some throttle. I am getting intermittent cam and crank sensor codes but not frequent. The only code I am getting is cylinder 4 misfire. With the way it is running it sounds like more than just that. If anyone has done this swap or knows anything that would help that would be greatly appreciated!
