When we cover it my idle goes down to ~250 rpms. Where is it supposed to go?

freegdr

is this from the 90 in your profile?

F1Addict

That doesn't look like a Renix.

My guess is this..........

the fuel tank has two evaporation lines, if yours is a 90 cherokee, maybeo you only have one, I know on my 91 the fitting on the intake has the lines from the fuel tank evaporation going to it. maybe its for solid fuel vapor delivery prior to injectors feedding mist to the cylinders for detonation, I dunno. got a shop manual? they are usually pretty good about the intake vacuum stuff.

jes' my 2 cents worth sir!

Gee oh Dee

Yes it does. Look at the TB.

Renix has that notch out the side.

freegdr

it went to the vacuum harness that should be there then came out other side around to the vacuum operated door on bottom side of air filter box

Hamster

Well on my 90 XJ, part of the CCV vacuum harness (which yours appears to be missing) plugs into that.

F1Addict

Fine, it doesn't look like MY Renix.

That vacuum makes a u-turn and goes right back into that molded vacuum line organizer thing that I have and you don't then off behind the filter box which I have and you don't.

Regardless, this is where that vacuum line goes...

freegdr

follow it again it goes to the baffle in the air filter box

F1Addict

I should clarify, that's where it goes on mine, which looks nothing like yours.

F1Addict

I followed it again, even more carefully this time. It still goes the exact same place I said it goes

That's a vacuum leak none the less. Fix it, then correct your (then), very low idle back to stock RPM.

freegdr

either way make sure theres at least a plug on it

freegdr

hugh maybe cali different from florida mines never been off in the 15 years ive had it

Parsnip

Yea it is the 90, but is this what you mean?
