I've searched all over the place and haven't been able to find this exactly, so hoping someone else ran into this. My idle started surging, up and down, up and down. I replaced the IAC with a used one and for two days the car idled perfectly. Now it idles low on startup and once warm will not hold idle. I can two foot it and keep it going that way but any time I let the RPM go below ~800 the engine just stops. In the interest of clarity, it literally stops running the moment it drops below 800, no sputtering, rough idle, or any other symptoms. Any ideas?
