How does an idle control valve work?
The idle control valve works by regulating the idle speed of the engine. The idle speed of the engine is usually controlled by the engine of the computer.

Would a problem with the idle air control cause a truck to stop and then start up again?
Yes, a problem with the idle air control (IAC) valve can cause a truck to stall and then restart. The IAC regulates the engine's idle speed by controlling the amount of air entering the engine when the throttle is closed. If it malfunctions, it may lead to irregular idle conditions, causing the engine to stop unexpectedly. Once the issue temporarily resolves or the engine receives more air, it may start again.

can an idle air control valve affect heat?
Yes, an idle air control (IAC) valve can affect heat in a vehicle. If the IAC valve is malfunctioning, it can lead to improper air-fuel mixture and engine performance issues, which may cause the engine to run inefficiently. This inefficiency can result in inadequate heating of the engine and, consequently, the cabin, as the engine may not reach its optimal operating temperature. Additionally, a faulty IAC valve can cause fluctuating idle speeds, further impacting engine performance and heating capabilities.

If the vacuum hose connected to the PCV valve was disconnected, it would idle poorly if at all, otherwise, no.
What would happen if you disconnected the idle control valve on your truck?
Disconnecting the idle control valve on your truck would likely cause the engine to idle erratically or stall, as the valve is responsible for regulating the air-fuel mixture at idle. This could lead to poor engine performance, increased emissions, and difficulty starting the vehicle. Additionally, the check engine light may illuminate, indicating a fault in the system. It's advisable to address any issues with the idle control valve rather than disconnecting it.
How do you adjust the Idle on a 1998 Dodge Grand Caravan?
