Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Throttle Kicker System
The throttle kicker system consists of a Throttle Kicker Solenoid (TKS) and a Throttle Kicker Actuator (TKA). The system is designed to increase engine RPM when the A/C is on, at high altitude, and when coolant temperature is above or below a specific range.
With A/C "ON", the ECA energizes the TKS allowing intake manifold vacuum to reach the TKA. The TKA is positioned on the carburetor against the throttle lever. With vacuum applied, the TKA will increase engine RPM for increased cooling and smoother idle. The TKA is also energized during engine warm-up or if an engine overheat condition exists.
