well the car is running rough, throwing code 32 and 43 EGR, and Knock sensor. I took the EGR off and cleaned it reinstalled it and a few days later its back to knocking and throwing codes. The first time I got codes it was throwing 32 EGR and a lean exhaust code. I forget the number.
 If I disconnect and plug the vacuum line that should close the EGR and eliminate the knocking correct? Any and all help is appreciated as this is not a strong area for me.
 update: when I push the EGR valve open at idle the engine will stall, just pulled the vac hose off, plugged it and went for a ride and Service Eng Soon light still comes on.

egr solenoid could be bad or faulty wiring/vacuum lines?
did you clean the intake egr port out?

When you say port did you mean on the valve or in the intake manifold? I cleaned the EGR valve up good in the port and internally with brake cleaner, the sprayed some in the recess to see if it leaked and it didn't look like it leaked. The intake manifold port, I could hardly get a finger in there due to the location

I meant the intake manifold, it's a real PITA, but with a mirror and a steel bendable pipe cleaner possible.

I'd check the solenoid before going back after the EGR. Miserable location to work back there.

well,.

you kinda need to read up on how, when, and why the egr opens,.

i would suggest the spring is week,.

plug the vacuum going to the egr,.

report back

I think you may have a vaccum, leak somewhere else in the motor,. leaning it out,.

Like the man says, Consider that unless you know that your hoses have been changed, they are 22 years old at this point.

Just to let every one know what the final result was. The EGR valve failed to hold vacuum, according to the FSM it needed to hold open and it wasn't so I replaced the EGR valve and the problem was solved. Thanks for all the input.
