Deceleration Fuel-Cut System: Description

NOTE: Camry, Celica (EFI) and Starlet models are covered in EFI ELECTRONIC CONTROL SYSTEM article.

This system aids in emission control and engine performance during prolonged periods of deceleration. System will cut off part of the fuel to carburetor slow circuit, thus leaning mixture and preventing afterburning and overheating which results from a rich mixture. System consists of a fuel cut solenoid, vacuum switch, computer, and connecting tubing and wiring.
