2.3L Engines Only
The coasting richer solenoid valve is controlled by 2 switches: the vehicle speed switch and the accelerator switch. In order for valve to operate, both switches must be closed.
When coasting richer valve is activated, solenoid in valve is retracted, opening a fuel passage in the secondary system of the carburetor. This feeds additional fuel into the lean mixture created in the intake manifold by deceleration action.
