    Default Evo idle problem. Help!

    Sup guys. My EvoIX MR is revving below 1000rpm to the point where it almost stalls. Right before it feels like its going to stall, it jumps back up to 1-2000rpm and it does it the whole time while the car is running.

    I dont know where to start looking, Everything is stock.

    IAC motor. My 9's broke at 50k. It's on the throttle body on the bottom. I tested everything from my o2 sensor to MAF before dropping 300 to get a new iac motor. Turned out to be it. GL
