Had the high idle(about 1500-1800 rpm) Removed the IAC and tested it. It has the 3 pins. Outer to outer pins were 41 ohms. Center pin to outer pin got nothing. I assumed it is dead. What years used the 3 pin IAC, so i can get one at the junk yard. I am bypassing the IAC by feathering the pedal when in neutral, works fine.
Thanks

Center pin is negative the outer pins are positive. Test with 12 volts, if the vane opens and closes it is OK.

Found my answer 83-86 for the IAC I need. Found it at a volvo graveyard. Spotted it driving down highway. It will be a good source fot parts.
Thanks for the imput. Always helps.

You should be able to disassemble that one and clean it. It may not be dead, just poor contacts. In the FAQs
