Is it a carb or one of those CFI units? I can find CFI vacuum diagrams, but not one for a carb. In any case, first, I would check the vacuum at idle. Post the results here. If you have good vacuum, then your issue is a likely misrouted vacuum line, not a vacuum leak. When you say you removed the emissions items, specifically what did you remove? Post pics of the stuff you took off. Good luck.
Pretty decent account for doing what you want to do here:
I removed the nightmare of vacuum lines, sensors, brackets, " smog control" devices on my 83 car...
I would recommend you go to your vacuum source and plug it completely first to see if this fixes your problem.. Then you could go back and reconnect each vacuum line one at a time to see if you can find your vacuum leak....
remember your " vacuum tree" on the firewall goes to multi sources.....

Hmmm. I’m no 85 expert, but I’m not sure what that canister supports beyond the AC system and maybe, the TAB/TAD valves. I’m sure it’s not part of the EGR system. Maybe as a test, hook it back up, and one by one, disconnect the TAB, then the TAD valves to see if one of them recreate the fast idle issue? Don’t leave any of them just disconnected as a vacuum leak. Good luck.
