Car shuts off after it turns on?

[Tman75]

So it’s been about three wks since I turn my 87GN on. I turn it on today and after a couple of minutes and shut off. It turn back on right away did notice the IAC# very high at 125. After a few minutes it went down to 25-27? Please any input would be greatly appreciated. And car did not shut off anymore.

I'd check all the electrical connections for signs of moisture. Might be a good idea to split the coil pack from the IGN module and make sure the potting material hasn't turned to goo.

Clean the IAC, too. Hi IAC after starting, may cause lean out, and a shut down.
