Finally got Demonica, our 94 Loyale, running perfectly with no check engine lights.  I tried swapping out the solenoids for the EGR twice with junkyard parts, and it was to no avail.

 

One thread had a mention of using 33 ohm resistors, so soldered and heat shrinked that up to the connectors and plugged them in, and then put new vacuum line in completely bypassing the two EGR solenoid valves.

 

Aside from needing a little bit of throttle to keep the car running for the first minute on a 25 degree morning the car runs perfect.  I cleared the codes and no check engine light came back on even after a couple of long test drives.

 

Is leaving the vacuum lines in place with no EGR valve a better method than just putting plugs everywhere?  I can live with the cold start if everything else is perfect.

I removed the EGR and replaced with a sealed cover or plate..in general all vac lines should be plugged to avoid any unnecessary air into the breathing system etc....35,000 later still running like a top...
