Ahh, I see what your talking about. When I got the jeep it had a cold air intake. So I think that he got rid of that. I just pulled what hoses I needed off that harness, bracket thing and put them straight onto the valves
Here's a pic, (airbox not installed yet)

I hope that was okay to do, or I'm out 50$ again

Yes I will be, I don't want anymore oil in there! Haha

Thanks for posting that photo up, Don.

Can the rest of you guys see where Flintstone cooked up a fish on his heat shield?

Use the good Felpro valve cover gasket with NO sealer.

Sounds good, thanks

Yep, from there right into the blender. Shad patties ROCK

So you have the top of that triple deal, to the FPR. The lone fitting behind it goes straight to the CCV valve on the rear of the VC. Those two and the front vent tube might be more important then the others. While you are in there make sure the brittle little map tube from the inside of the TB, back and up to the Map is flawless. Very important, that one.

Yeah I think I messed something up cause now I'm having a rough idle haha I think its the map

Correction: Has a terrible time starting now, and dies randomly

Listen for a hiss. Triple check that MAP tube. The large"ish" vac line coming off rear of the tb goes all the way back,across and around and down tho the vacuum ball/reservoir behind the right front bumper. There is a "y" with a small tube to the vac switch on the T-case, (4 the disco), near the canister.

I checked that tube and it seemed okay, I did not any hissing from there
It's just so weird because before I did all those egr tubes the thing ran perfect. Once I got All the hoses hooked up correctly, then this started
I don't know what could have changed.
This censor didn't even have anything atatched to it and it wasn't plugged in.

And now that the correct tube is on this(instead of the rear breather tube) this should be correct

I put the rear breather tube to the valve in front of the throttle body
The only questionable item is this

But theres no tube to put there cause I cut that part off to install my snorkel
I will clean the throttle body tomarow to see if that helps

DFlintstone

Well, just for diagnoses disconnect the EGR diaphragm tube . (n plug it) It should only get vacuum at certain times, like when your are at temp cruisen. "back in the day" you would need to be in drive, or high as well. That thing it's self will be a vacuum leak it it's opening at the wrong time.

Likewise you can temporally pinch, or cap off that big line from behind the TB around to the vacuum ball see if that helps. (heater control, cruse, and vac disco won't work without that)

The EGR gets it's vacuum from that solonoid controlled vacuum switch. The double nipples there on the air box is a temp controlled vac switch. When it's cold it moves the flapper there to bring hot air to the air-box from the manifold. I'm actually thinking about hooking mine up. Completely harmless, and might help it warm up faster.

I clamped that vacuum line to the vacuum ball and that didn't help, I also unplugged every egr tube and each one was sucking air the whole time, I think my egr is bad

I don't know if it's related but now I have a grinding/ humming/ screeching noise coming from around my throttle body... Only happens at low rpms and 5% of the time, also only last for a second or two

884x4

Well I got a surprise , when I took off my throttle body for cleaning this is what I found underneath it... Anyone want to point me in the right direction as do what to do about this? I assum it's not supposed to be like that

Thats pretty normal.
