Civic EG

ok every one i left my ls hatch idle today 1st time i had the car idle with a DA integra ecu obd1. when i started it, it sound really woppy but no cel was on so i wait ten min and the cel of iacv cel 14 comes on. but while the car is idling i unpluged it and nothing happens still idles the same as if it was pluged in ?

make sure your using the right plug first off, the evap purge and that one could possibly be switched depending on your harness, the other thing to try would be to pull the valve off the back of the manifold, and clean it with a carb cleaner or something like that, but it may just actually need to be replaced.... those are just a few things to try first, low coolant level will cause a surge in idle, but ive never seen that throw a cel...
