92 NA Miata idling oddly.

Occasionally my 92 NA will idle high, almost at the same speed it does when the AC is switched on, however if I actually switch on the AC it’ll drop to a normal idle speed. It doesn’t always do this and I honestly have no clue where to start on a fix for it.

Possibly something up with the idle speed control valve? maybe an ecu thing. All I can think of

[@der_pinguin44]

Idle air control.

Sorry, I do not know much about car mechanics. I am here from LGR where you sent him a mini CRT TV. I was hoping you might have some insight, sources, or suggestions. I would like to scrap one together myself as a little gift.

[@cdigames]

ISCV is 90% the cause.
