probelms with idle on 92 z28

i purchased a 1992 z28 two weeks ago and just started to have problems with the idle. you can head the motor rev and them drop in rpm's. also u can watch the tach jump. maybe the iac ? not sure

If it revs then drops once on startup, thats normal. If it continually changes RPM for no apparent reason, then you have a problem. Let us know which is going on.
