This seems to be about 1,300 rpm on the 2.1. This doesn't change anything about your procedure, but on the 2.1l the closed-throttle switch does affect idle via the much more intelligent idle speed controller vs the 1.9l. On my '89 if the idle switch is working the warm engine idles down to ?1200? - I forget exactly - for a couple seconds, then drops to 900+ and stays there. If the switch isn't working, it has a slightly unsteady idle a bit above 1,000 rpm. I've never tested a different idle speed controller, but even if this is not correct behavior of my idle controller it still shows that the controller is cognizant of the throttle switch.
