do you have a vacuum tester? i'd never try to diagnose problems without one, all major auto part stores sell them. test the lines, be sure theyre at fault, and replace as necessary.

yes, you can run a new line from the tree to replace the faulty ones.

Note that there is no vacuum going to the EGR valve at idle, WOT and cold engine.

When you put vacuum on the EGR valve at idle the engine should run rough or die.

I recently had this same issue! I did the same and ran a new vacuum line to the solenoid. Worked like a champ.
After I tee'd into the line to egr with a vacuum gauge running up to windshield under wiper and watched the vacuum kick in under cruise only after warming up as its suppose to function.
