ISSUE: "Hot Engine Stall" on tip-out at low speeds (25 mph/40 km/h or less) during the engine initial break-in period (100 to 1500 miles/165 to 2500 kilometers) may be caused by the strategy of the EEC IV processor. Self-test code 11 will be displayed during diagnosis indicating the system is okay.

ACTION: To correct this, install a new EEC IV processor (E7TZ-12A650-CB) and perform the service procedure to reset the idle speed. Refer to the 1987 Engine/Emission Diagnosis Shop Manual, Volume H, Section 4-17.




Obtain an Authorized Modifications Decal and list the date, dealer number, and summary of alterations performed. Select a prominent place adjacent to the Vehicle Emission Control Information Decal suitable for installing the Authorized Modifications Decal. Clean the area, install the decal, and cover it with a clear plastic decal shield.
