wierd idle 700 1989

Started my car this morning and the tach went to about 1500 like it always does then dropped to about 500 and lumped around there. This made me nervous so I touched the gas a little and it almost died. Then I didn't want to hurt anything so I shut it off.

Ignition: I just replaced the spark plugs with new NGKs but I didn't check the gap before they went in.

Fuel: all pumps and injectors seem to be working. The FPR is new and does not leak.

Other: What about the IAC? I don't know how to diagnose this. What about a dirty TB or my TPS slipped?

Thanks in advance.
plan for today: read FAQ, go out and try stuff.
