Check for a malfunctioning EGR valve. This valve is only selected to perform when the engine is warm. It has a vacuum diaphragm which can crack and lead to vacuum leaks. This will cause rough running. The EGR valve should be vacuum checked to see if this diaphragm is leaking. This valve can also stick open due to carbon deposits. When the valve sticks open, the fuel/air mixture is leaned out and rough running ensues. This problem is practically expected on a vehicle of that age.
EGR system malfunction. Check EGR circuit/switches. Check/replace EGR vacuum hoses. Check/replace EGR Vacuum Modulator. Remove and clean EGR valve. Test EGR valve by applying vacuum to open. If necessary, replace.
The main vacuum line from a vacuum source on the intake goes to the multi-hose valve on the top and the distributor vacuum advance.This multi-valve switching valve is the main connection to the other vacuum hoses on mine. Two lines come in from a vacuum source and thre go out to three components according to tempature. On mine the middle one off to side 1)goes to choke opener and switching vacumm valves mounted on the fenders the other middle one 2)second from top goes to another choke opener and EGR Valve and EGRModulator. The bottom hose connection is on when cold 3)and goes to a part on the carburator to help it run better when warming up a AAP valve.
There is a check valve diaprham thing inline to the EGR vlave on the second line from top.
I have another vacuum line on the drivers side of the carburator that has a check vlave inline but larger it goes to the throttle linkage to help slow the closing of the trottle on rapid deceleration.
If you are talking about the Theft deterrent ECU it is behind dash above left kick panel.( near drivers left foot) all other moduels are behind glove box, behind passenger side right kick panel or under center consel below stereo and next to storage box in front of E brake handle.
