I still have that black wire cover? in the way of mine, but all I saw were the 2 next to it. One goes to that black box all the way to the right in your picture (some kinda of MAF sensor?) and the other goes up to the firewall and splits.
Dont see another nipple, but like I said, my jeeps normal and I can only find two. I certainly cannot find the third nipple on my Jeep. Is that a good thing?
by the pic, it seems I'm missing all in the blue lines. What you see in my original photo above is all that is next to the black box (which has one vac line connected to it)....what am I missing?.....how important is it?......and what do I do with the vac leak until I get the rest of it......remember your dealing with a noob here...
havnt checked the rpm, but a pretty good drop, and seems to idle smoother with it closed. havn't tried driving it with it closed to check preformance closed either.......don't know if I should plug it or leave it open.....runs fine like it is....I'll try the other way tomorrow eve...... I know it has enough suction to just about pull your finger in it.....
mines is just like yours and the only difference i visually see is the color.. Mine is pluged..it's not suppose to be open just like that i'm guessing the old one slipped of on accident while wiping the intake manifold. Junk can get in/through there. If you want to live it open i'd at least recomend putting a little filter on there..
I'm guessing its a manifold that they never bothered to redo.. its a plug for something extra but since the 00 model doesnt need that (so it seems) they just left it there and pluged it since it's cheaper to use the same old tamplets and also if a vacume source is needed that can be used since its free. It preatty much just has a hole that allows unmeasured and unfiltered air to enter the cylinders when its unpluged. I dont think it will affect much performance.. i believe idle will be the big affect because it allows unmeasured air to enter so it doenst add the fuel.. maybe i'll do that to mine too so it lower the fuel going to the engine at idle.
