He started it, Swansen.

Right....just as I was feeling a tad guilty for falling asleep, too. <<(and, no comments from the peanut gallery....please)

Yeah, get some pics. The 4rnr's home and I can help route whatever you need today.

 

Okay, here are some pics of it. I'm sure when I'm done getting things together it may become evident where it goes. I'd like to know ahead of time though, if possible.

 

looks like my power steering idle up lines just blocked off all cool like lol

 

I think you're on to something. Underneath the power steering fluid reservoir, on the left and below, is that where the hoses go? If so, I've got a busted air valve.

Can anyone take a pic of that location for me?

Edit: I found a pic, and I do have a broken air valve. The plastic ports are knocked right off.

 

Hey.....take a pic of your broken valve. And, get a part number. I might have one, if you'd like.

 

Yep...they look like the ps pump vsv lines to me. I got one from a pick and pull for $10, could have had the whole pump for $25

 

It's definitely a broken valve on the pump. Dealership wants $97 for one new. I might go to the local yard and see if I can get just the valve (this yard is kinda pricy sometimes).

 

If you cant find one...search dirtoyboy on yt, I bet he'll have one, and he has good prices from what I can tell.

 

Umm.... I might have one that will work for your truck. Just need a pic and/or part number to see if it'll match up. I'll make it cheap, too....

 

Cyberman -

Did you ever get this figured out?

Your photo shows the AC idle up valve. When the AC is on, the valve is opened, and connects the two hoses together. The hoses are supposed to be connected to the air intake and to the plenum (see diagram below); when the valve opens it allows a little extra air into the plenum which raises the idle. Connecting the two ends together as shown doesn't do anything. If the port on the plenum where it is supposed to be connected is not capped (or filled with crud, same thing) then you're idling a little fast (or, put another way, when you plug that port your idle will drop, and you may need to adjust it.)

Same deal with the power steering pump, though it sounds like you're missing that one too. On the power steering pump, when the pump is really straining (like if you turn the wheel all the way to the lock and keep pushing), that valve opens up and raises the idle. Otherwise, you could kill the engine trying to get out of a tight parking space.

If these port are just left open when the hoses were pulled, you've already turned your idle up all the time. Not good in the days of $4.50/gal. Or, someone pulled the hoses and capped the ports. Or, pulled the hoses, and then turned the idle back down (but losing all "idle up" capability). Whatever: when you get this stuff hooked back up you'll need to check where the idle speed ends up.

But first: when you find the port on the plenum, put your finger on it while the engine is running. Does it suck? It's supposed to. Because of the EGR (and other things) the plenum tends to fill up with a startling amount of crud. I had all the vacuum lines hooked up, but never really noticed the idle-up. When I did a top-job (blown head gasket), I spent a lot of time cleaning out the plenum. Voila! Idle-up was now evident!

Good luck!

 

Yes, I got everything squared away with the hoses. I didn't get a replacement valve for the power steering, but got it back together.

 

I think this vacuum line requires the BRUSH ATTACHMENT ...

 

Just to add in on this one... DONT EVER BUY A MERCEDES. everything on it operates off of vacuums. From the A/C switches to the Headrest. My mom has one and has had me check stuff out on it and I have no clue where to start. If you hate vacuum lines don't get a mercedes.
