Unplugged the IACV, idle starts loping?
2000 accord lx 141,xxx miles f23a4 motor, 5 speed manual. i was going to adjust my idle, so i unplugged the iacv like i read your supposed to and the idle started loping. it was jumping from from 1000 to 1200 rpm. so i was always told that the rpms should either drop or rise depending on where the idle control screw was adjusted to and it did neither, it just started loping. it doesn't happen when the iacv is plugged in btw. what could possibly cause this?

When you adjust the idle you need to pull the radio fuse or the negative cable for 30 seconds or so so the ecu can relearn the idle. Assuming you don't have a vacuum leak, the ecu needs to relearn the idle. But, before you restart the car after plugging the iacv back in you need to let it completely cool. Then start it up(in the morning or so) and let it idle until operating temp.
