How a bout try to post a video? It could help us hear it, and diagnose it better.

Definitely get all lines back together, that may be your issue. Have you cleaned your ccv lines when mine get clogged it idles a little low, rough. The rpms are supposed to drop when you put it in gear, that is normal.

I know my revs drop a little but they never used to drop that low. Thought Id show that they go near 500 and below instead of 750 and above. Ill check those, nice and easy. Might as well check my MAP sensor and see if D/Cing my EGR leads will help any. I know its not vital and people remove them sometimes but it could be causing issues. They're ridiculously expensive for such an innate part. I have access to an air compressor with a needle attachment that I use to dust computers. Thats more my forte but I'm not bad with a wrench either. Ill have to visit FNJeep, local jeep graveyard, and try and replace some parts that those leads lead to. I figure that the reason he's acting up is because Colorado has been cold up until a couple weeks ago. So all the air is rising and is less dense than it was over winter when it was all settled on the ground. Im contemplating a CAI so Ill check and see if it has connections to those leads, which I hope? So its not a moot point. A buddy of mine owned a CAI in a jeep that had no Preheater hose connection along with other lines.

Also this was told to me on Facebook today

"I'm willing to bet the amount of money that you have spent on your jeep you could have bought a different jeep and done a few repairs on that and been good."
Ha. Ha. Ha.

So the hose I repaired from my intake manifold that leads to my bumper, a little black ball which has two hoses coming from it. One to my manifold, previously said, and one smaller one into my firewall. When its D/C'd the engine runs alright but still a tiny bit choppy. Im working on other vacuum hoses and such. I cannot remember what that football shaped thing does and I want to assume its for AC? Not too sure. Anyone have any ideas? Maybe it needs replaced?

Could it be causing my issue? I tried blowing in the hose that goes to it and it seemed clogged. I have no idea if its supposed to be that way.

Been reading up on what it does as far as vents and CC, but it still confuses me that removing it from my manifold increases my idle speeds and performance. Not to where it used to be but still an improvement.

So this weekend Ill be putting a breather valve on my valve head to avoid having to have it go to my intake just in case that may be an issue. Ill figure out sometime this week how to plug the intake. Also buying new hoses and a relay. Checking a bunch of other things out. Ill be out of town but ill have a garage so ill try and bring a laptop with me.

So Ive been replacing grommets and hoses amongst the latter. I also did this because I was at FNJeep getting a new Cruise Control and an EGR valve over flow blah blah I forgot what its called. Also replaced my Ceramic Fuel Pump Ballast Resistor because while I was researching vacuum hoses and such that it could be problematic with rough starts and idle speeds. Regardless, Im still a little stumped.

I was pokin' around again trying to find more vacuum leaks or something and I crawled under my engine and inspected this air canister from underneath and heard a vacuum leak and saw this. I couldn't tell if it was the source and I cant really tell if its vacuuming at all but I'm hoping this is somewhere. Any leads?
