Quick facts
- Part: Standard Ignition AC474 idle air control valve
- Fits: 1998-2002 Honda Accord 4-cylinder 2.3L and other vehicles
A rough or hunting idle, an idle that sits too high or too low, or stalling as you roll to a stop can mean the valve is sticking or has failed. Before you replace it, rule out a vacuum leak, carbon buildup in the throttle body and a wiring or connector fault, since any of these can also upset the idle. Each engine takes one valve.
