There is nothing wrong with your AAR. If it were sticking open you would have a high idle not a low one. If it doesn't open at all you should still be able to start and run the engine using your right foot to maintain a high idle. Not being able to do so eliminates the AAR as a suspect.
Once you get your IC put back on fire the engine you will see how it operates with the intake leaks reduced or eliminated. You could still have cracked injector blocks but finding loose bolts will make a difference. Finding the root of your cold start issue is a process of elimination as all of these things mentioned can contribute. Hopefully it is just one thing and not the degradation of multiple things that is causing the problem. I think the loose bolts are the culprit, but if not the engine will start/run easier which will further help isolate (the rest of) the problem.
