Idle Stop Solenoids
The idle is how the engine runs when it is out of gear or not moving. Many different components are a part of the idle system to keep it running at the correct speed and to help the engine be efficient. The idle stop solenoid is a solenoid that is electromagnetic. It creates a magnetic field when exposed to electrical signals. The magnetic field holds the carburetor link up closed or in the cold position. It controls the idle speed by moving the throttle plate when the engine is running. It also controls the throttle place position when the engine is off. This prevents dieseling. Dieseling is when the engine continues to run for a moment after the ignition has been shut off. Repair to the idle stop solenoid usually is included in major tune ups, where the position of the striker inside the cylinder is adjusted.
