Does anyone know what the specs should be (ohms/resistance) in a properly working idle air control ('04 2.2L 5 speed Ecotec)? I was having a problem with my idle dropping out and stalling, fixed that but after the engine is warm, my rpms will sometimes drop to about 500 then bounce back to idle (1100) when I hit the clutch. Already replaced the TPS, PCM, IAT sensor, and MAP sensor, so my only other guess would be the idle air control.
