car shuts off randomly
hey while im driving at low speed and sometimes at 60 my car just turns off randomly, i just recently changed my air value control also, can anyone please help me!!!

6mt swapped..smart
The IAC could cause the car to shut off- mine has in the past. When you push the clutch in the rpms dip and just don't "catch" themselves and the car dies. It's only happened once or twice, but definitely possible

It is auto. My car was idling rough. Has gotten better since I replace the air control. Thought it would slove the problem. And it hasn't. And its starting to piss me off lol

Check your grounds, specifically in the engine bay.

There's only one component on the J32 that electronically controls the idle speed and stability: IAC valve. That doesn't mean the idle couldnt be affected by any mechanically issues. Especially those that the IAC valve couldn't compensate for...like a large vacuum leak. I see J32's all the time in my shop most commonly for 2 reasons: misfires and idle problems.
I see many defective IAC valves especially when bought aftermarket. I've learned it's best to go with OEM. There's three circuits on the IAC. One will be a power (with engine running), the other a ground and last is the ECMs signal to actually control the valve. It's easy to test power and ground but the signal requires a bit more finesse when using a standard DVOM (voltmeter) and any scanner that has powertrain functionality control. If you're pulling any type of code that pertains to IAC circuit (in specific), then chances are your issue is not directly related to the IAC valves circuitry such as the harness and/or ECM. Although you could still have an electrical issue.
As I mentioned earlier, there many other mechanical issues that could be contributing to your issue. Vacuum leaks, air-distribution issue to IAC supply (clogged/dirty), throttle body valve (dirty/clogged), intake blockage (generally associated with low power), just to name a few.

^ The IACV wont cause the car to stall at speed. It only controls idle.
OP - Looking over this thread again, Im surprised it hasnt been asked yet. Any check engine lights?
