2000 Ford Escort Won't Idle.

I checked all the vacuum lines I could find and thought maybe I found one that was the problem. I replaced it but still won't idle. I found a picture of the EGR valve online but can't find anything like that, where is it?
Thanks,
Rob.

Ok Thanks. I'll see if I can't do that over the weekend and get back to you on Monday. I was reading up on the EGR and it looks like its something that can be cleaned and maybe get workin again before I'm forced to purchase a new one. Thanks for your help, I'll let you know how it works out.
Have a great weekend,
Rob.
Oh the Idle air controller. Is it on the opposite side of the throttle cable and can it be cleaned also? Looking at the motor from the front bumper, the throttle cable is on the left and there is a controller thing on the opposite side that I thought looked like maybe was a choke cuz normally from that side it would be a choke. If this was a Normal Carb Throttle body, I would have just rebuilt the Carb.
Again thanks for your help.

Ok so There is a long plastic hose with a silicon based elbow on each end that connects the exhaust whatever valve to the EGR valve on th intake. It runs around the motor under the electronic ignition. That hose had a crack in it almost in the middle of it. Replaced it and its runnin great once again.
Thank you for all your help.
Rob.
