I know this has been beaten to death, but I cannot find this info..

If I pull of the vaccuum line on the side of the EGR and plug it, and I still get the hesitation on light throttle acceleration, does that mean that its the solidnoid? What if I unplug the solinoid and leave the egr vac. port on?

(gettin code 32 when on hwy for about 20 min, and have light throttle bog and hesitation, which is fine at WOT)

Any other way to test either?

Vacuum switch is used to activate EGR valve by applying vacuum to it. You may have a leaky switch - disconnect and plug on the supply side of the EGR switch. Code 32 is a result of ECM performing a self check during highway cruise by cycling EGR control valve and monitoring MAP sensor readings. I think I've mentioned this in prior posting. Look for other problems - vacuum leaks, not enogh fuel presure, etc.
