newbie egr question

[BlackVert]

what does the vacuum line on the egr go to, the intake?

i just noticed that i didn't connect mine to anything and i don't have any unconnected vacuum tubes ...

the red and green lines go from the intake and the egr to the fender, along with the lines for the smog pump. not sure what the piece in the fender is called

and you need to get them

Seems to me that the vac line to the EGR snakes under the TB and runs down the pass valve cover. It then exits stage left and heads for the inner fender on the pass side (where the charcoal cannister, etc is). The line should go to the EVR, which is a solenoid that controls when the EGR gets its vac signal (during cruise conditions).

The line around the EGR valve is hard plastic and gets brittle (dont ask how I know - mine is patched together).

Not sure if that helps or not but.......

do you have a check engine light

edit, just noticed tweecer

evr ... do you mean that little cylindrical thing up near the firewall on the passenger side with the rubber around it that has a tee on top where one side goes into the fender to a box near the door and has the electrical connector on the bottom? i'm pretty sure that is the one you mean.

so the other side of that tee goes to the egr valve? wow, i have it hooked to the vacuum side of the blower ... oops! that might explain the high idle ...

gee, i better take a pic of my vacuum lines for you guys to tell me what else i have wrong ...

Nope, it seems to me that thing you are talking about is the purge solenoid. It has a line running under the upper intake to a port, where it infuses vapor from the charcoal cannister (which is in the pass fender). This is all part of the EVAP system, not EGR.

I would have to get out the factory manual to find the EVR (EGR vacuum regulator). I did not see it in Haynes the last time I was farting around with my EGR stuff.

ok i think i'm on the same page with you now. the egr vac port goes to one of the three hard tubes that all come together near the alternator, right? i think the tubes have different colors ... which tube is it?

i plumbed two of the tubes together to the vacuum side of the intake. that is where i made my mistake.

On my car the red line went to the intake, but Im not sure which line went to the EGR

i may be able to figure it out now due to process of elimination. not sure tho because i'm at work and the car is still sitting in the driveway at home ...

a little off topic, but my hard green line is cracked i think, and i was wondering if that was something i could buy at napa, or something i had to order online. any
info. appreciated. thanks

i would think you could get it at any auto parts store.

Chris, you are getting some good help. I could not tell ya off the top of my head which color lines are for what. Others will though.

87GT, you can buy generic runs of the hard plastic line at the parts store. I broke the line to my EGR right at the top where it connects, so I just used a small piece of vac line as a splice for now. At some point I will redo all of those brittle plastic lines.

Good luck.

o.k. you have 3 hoses exiting the intake tree between egr valve and fuel pressure regulator.
1 the large black hose exits runs down firewall to drivers side into the vacuume distribution box.

2 small black hose plugs into the fuel pressure regulator.

3 red plastic hose into fenderwell into egr vacuum regulator solenoid.

then a green plastic line exits the egr vacuum regulator solenoid then out of fenderwall to the egr valve.

the red and green plastic lines run to and from egr vacuum regulator solenoid to egr and vacuum tree, side by side with a connector at the airb (air injection bypass valve) valve where a white line exits connector and plugs into airb valve.

good, info, but im having a hard time visualizing it. anyone have a picture?
