Some vehicles may stall on deceleration and/or have an intermittent stall in warm weather. This may be caused by the vapor control valve not supplying a steady flow of fuel from the tank to the intake manifold.
Replace the fuel tank, vapor control valve, fuel fill tube cap and clamp. Install heat shield over fuel tank and reprogram the Powertrain Control Module (PCM). This should reduce the possibility of stalling. Refer to the following text for details.
Perform all diagnostics for stalling by following the procedures outlined in the 1996 Powertrain Control/Emissions Diagnosis (PC/ED) Service Manual and 1996 Taurus/Sable Service Manual, Pages 03-13-5 through 03-13-8. Check to be sure Grounds 401 (sedans) and 400 (wagons) are secure. Check for a kink in the canister vent hose and repair as required.
If no other concerns are found, reprogram the PCM using the latest level CD-ROM update disc and refer to the following PCM Application Chart for correct PCM usage. Replace the fuel tank, vapor control valve, and vapor management valve by following the procedure outlined in the Instruction Sheet included in the Fuel System Service Kit.
