I just responded to your faulty oil pressure thread, and now that I just read this thread as well... it sounds as if, perhaps, somebody was playing around with the needles inside of their cluster box????
Seriously though, although she's embellishing 600-RPM in park/neutral (you were referring to park/neutral when idling, right)... how does she feel? Does she sound like she wants to stall at any particular time?

If the only problem is a low idle, try adjusting the Idle Air Control (IAC) first. What I'd do, is, remove the IAC sensor from the throttle body, and give it a thorough cleaning inside by the pintle. Use plenty of carb cleaner, and an old toothbrush to remove the unwanted carbon. Be gentle with the stock gasket, as you'll need to re-use it for now...
Aftwerward, search for a technical article explaining how to re-set your idle. Search for the keywords of: ALDL, IAC, paperclip, throttle body. If that doesn't help, we'll move on to the next possibility...

If the stems are still prevalent, remove the exhaust manifold yourself, and spray a good amount of WD-40 in where the broken bolt stems meets the head. Once you allow it to penetrate, lock the stem with a GOOD vice, attatch an extension to the vice (for leverage), and remove the stems yourself....
As for the freezeplug, again, I would do it myself, but being that you might be new to this, have him take care of that (and only that) for you. Remember, he's in business tomake money, and will be looking for many things that need fixing. The broken exhaust manifold bolts, although causing and exhaust leak, can wait for the time being. But the freeze plug, yes, you'll want to have that taken care of as soon as possible...

Clean the sh*t out of the throttle body as well. When those air bleed passages get blocked, the car will not idle right. I bet once you clean the TB and IAC, it will idle much better.

Your idle only needs to be as fast as the engine needs to be running to not stall. The idle is controlled entirely by the computer and the IAC. Typically if the IAC is bad or plugged (not too uncommon due to pcv breather in front of throttle body and blowby) it won't idle at all, or it will stall coming to abrupt stops. It wouldn't hurt to clean the IAC and the passages in the throttle body, but as long as your engine stays running it's not a serious issue. If the problem is roughness of the engine at idle, it may be another issue altogether, such as fuel delivery or ignition.

by the way, broken bolts are easy to get out... get something called an "ease-out" ... any good mechanic store should know what you are talking about... and get the square head, not the round!
