Do you have a diagram of what lines you changed ?
I just found a split in the line from throttle body to EGR. I guess I should replace them all now. Can you help me out?

its very easy to tell which lines to replace as they are all the pliable rubber or cloth covered rubber that run between the hard nylon colored lines and the various ancillary devices the hard lines connect to. They're all very short with most being 3" or shorter and some (model dependent) being as long as 9" or so. Most are behind/under the MAF housing and some are near and including fuel pressure regulator and yet others are near the cruise control diaphram. All colored lines, ie; red, blue, green and black terminate with a soft cloth-covered rubber line from the factory. Just replace any/all soft cloth-covered rubber lines on everything you can see.

According to the diagram of throttle there is a line from there to EGR frequency valve..thats where I have a rubber elbow joined to a metal tube to EGR. Split in elbow. Thanks for tips on vac lines.

I assumed since you asked Hokie that you had a 12V. There is no EGR/TB connection on 12V. My mistake

Like UrS4 said, I just replaced all of it. We have 2 different engines though.
