WARNING: THIS MODIFICATION IS AUTHORIZED ONLY FOR THE LISTED ENGINE. PERFORMING THIS MODIFICATION ON OTHER ENGINE CALIBRATIONS IS UNAUTHORIZED AND COULD CREATE LIABILITY UNDER APPLICABLE FEDERAL OR LOCAL LAWS.

ISSUE: A hesitation, stumble or stall may occur during the first two miles (four KM) or three or four minutes of driving after an initial cold start at ambient temperatures of 50~ F (10~ C) or below. This condition may be caused by the strategy of the EEC-IV processor.

ACTION: Perform the procedures to determine if a new EEC-IV processor with revised strategy is required.


1. Follow the diagnostic procedures in the 1992 Powertrain Control/Emissions Diagnosis Service Manual and service as required.

2. If the concern still exists, install a new EEC-IV processor (F2DZ-12A650-CC).





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.
