vac lines are correctly hooked up. I just ran the test you suggested and there was no clicking from the solenoid at all and no re-routing of vac at all to EGR. Also, noy after removing the EVR and attempting to clean it out earlier I am getting a code 84 on the KOEO test that I wasn't getting before. I guess this brings me back to the prior question... Where can I get one? I guess I need to have it for the EGR system to function properly.

I turned it over and lots of dusty crap fell out, so I sprayed some electrical parts cleaner inside of it. I guess it didn't like that!

So, I found one from Autozone for 25.99. Guess I'll try one tomorrow. How will this affect my driveability? Will it make a diff?

Code 33 is the code that will be logged in the system when you install the EGR simulator resistors pack.....it means the valve is not been registered as opening (EVP signal change). The only thing this code will cause is have the EEC-IV system delete/bypass the EGR function w/out causing any driveability problems. If you want to solve it though, need to check the vacuum lines to/from the EVR solenoid (the one behind the RH strut tower on the top).
