What is this? there's a hose that leads to no where.. Anyone care to explain what it is? Thanks.

 

It looks to me like a vaccum line that should, if memory serves me, run around the air box and either hook into the side of the air box or into something on the intake manifold. There should be a diagram on the underside of your hood showing the routing of the vaccum system. You should be able to trace it with the diagram. Good Luck!!

 

looks like it could be a vacuum hose for cruise control. do you have cruise control?

 

EGR solenoid, this is a renix jeep.

 

On my 90 there is a block of vac terminals there by the power steering. That line (mine's also un-plugged), ends near the lower forward nipple on that. I think it use to go there and when the rubber "L" fitting went to $hit, I just capped off the nipple.

 

Nope.
Whats the egr solenoid?

 

evap psi pump. builds pressure in your evap system to test leak down in your fuel tank for emmisions. builds up to 3Hg water weight and holds it till test is complete to pass monitors during emmision check in the computer.

 

no... EGR solenoid... Do I really have to post the FSM page?

 

X2

Soo what happens if the egr isn't hooked up right?

 

Without it you might get high NOx at a smog check. If it's coming on and dumping exhaust in your intake when it shouldn't it won't run right. And last there can be a plane old vacuum leak if the right hose is off.

 

I just checked and it looks like almost all my hoses are on wrong.. The engine runs fine but it's completely wrong. Should I mess with it or leave it?

 

thanks I always wondered what the ---- that was
