My WRX is my first AWD and turbo. I don’t know if my issue is Subi based because of it. At idle rpms nearly fall flat but quickly recover. I’m almost positive it’s in the air/fuel management system. I’ve already checked the air filter and it’s fine. Any ideas what the issue could be?

What year car? What mods? Can you describe your problem a little more clearly

2017, bone stock. I’ll be sitting at a light and the rpms drop almost to the point where the engine shuts off, but the ecu catches it and corrects the issue momentarily until it happens again.

Does it happen when you’re already stopped or just as you come to a stop? I experience the latter a lot. It’ll shudder a little, go down to 400-500 RPM, then bounce back up. It’s never stalled. I’ve been ignoring it for about 25 months now.
