      Ok, that sounds like what you have is a *code reader*, it's not a scanner. A proper scanner is more advantageous to one. The scanner will clear that code, the scanner will run a diagnostic on all of the sensors in the system. It has *realtime* capabilities, as for the IAC relearn this scanner will go thru the steps needed. Look on ebay for a used complete scanner kit, the replacement for the OTC 4000E was the OTC Genisys SPX system, a newer version, capable with both OBD1 & pretty much all OBD2 up to 2010 until the EVO replaced it. Even if it sounds like a somewhat expensive initial outlay a scanner is a worthwhile tool to own.

      I have the little Gm plug in style. And the code comes up as a 35 and in the code book says ( IAC system problem-can not set desired RPM. In service manual it says that it has to be relearned with the Tech 1. I was wondering if there was a way around that.

      You're more than likely going to find yourself on ebay looking for one, everything in the market today is geared to OBD2. Some older models would read OBD1 & OBD2 up to a given year depending on the plug in cartridge. The interface for OBD1 was not a single standard plug, it varied on the vehicle manufacturer & so did the harness to the scanner. The item I own is an OTC 4000 enhanced.   https://www.ebay.com/sch/i.html?_nkw=otc+monitor+4000+enhanced&_sacat=0&_from=R40&_trksid=p2334524.m570.l1311&_odkw=otc+monitor+4000&_sop=12
