Engine - Stalls During Deceleration At Low Speeds

FORD 1986 TAURUS
Stalling during deceleration from low speeds when the engine is hot may be caused by a saturated carbon canister. When the canister purge regulator valve (CPRV) closes during decel, the flow necessary to run the engine may be suddenly shut off. The fuel system does not react fast enough and a lean condition occurs causing a stall. To correct this, a restricting connector should be installed in the purge system that will allow a small amount of flow to bypass the CPRV. Use the following procedure to install the restricting connector.
1. Cut two pieces of 1/4 inch bulk hose (DOPZ- 12226-C) approximately 2-1/2 inches long.
Figure 5:
2. Cut both vacuum hoses that attach to the CPRV approximately two inches from the CPRV, Figure 5.
3. Install the (E3FZ-9K319-A) restricting connector into the purge system. Use two (383014-S) vacuum tees and the two 2-1/2 inch lengths of 1/4 inch bulk hose. Figure 5.
NOTE: Install the restricting connector higher than the CPRV so that it does not act as a trap for vapors.
