I don't kknow what Acura you have but on my 1990 integra gs low coolant level will cause the erratic rpm. Also the intake manifold gasket could be leaking causing an erratic rpm condition check all your sensors, mostly the throttle position sensor (on the throttle body) also check to make sure you dont have any vacuum leaks.

Why do you want to unhook your battery??? If the alternator is good the car will continue to run, if it dies then you have a bad alternator this is why you would want to unhook the battery cable to check and see if you have a bad alternator

Check the alternator. 90% of the time that's it.
Get engine running. While the engine is running disconect the POSITIVE termninal from the battery. If the engine dies, the Alterntor is bad.
If your alternator is good it should stay running until your engine dies from no fuel.
