WHEN SHOULD THE IDLE CONTROL VALVE BE REPLACED
Incorrect Idle Speed
The car will feel like it’s going to stop as your RPMs drop. An IAC valve that is left open will cause an excessive idle speed. Even though the engine is not running, it will still run very fast
Bad IAC valves can cause surging conditions at idle. The RPMs will rise and then drop to normal
Check Engine Light Is On
The automatic car sensor oversees the IAC valve to ensure its adequate function. The sensor triggers the check engine light if it detects a fault
Car Stalling
A bad IAC valve can cause a vehicle’s engine not to get enough airflow to move, causing it to stop completely
The Car Won’t Start
In extreme cases, the IAC valve may prevent air from entering the engine when it is functioning, resulting in an engine that won’t start or crank
