WARNING:
This modification is authorized only for the listed engines. Performing this modification on other engine calibrations is unauthorized and
could create liability under applicable federal or local laws.
ISSUE:
Stalling may be experienced after a "cold" start-up on vehicles with less than 500 miles (800 kilometers) in ambient temperatures of 50~F or
warmer (10~C or warmer) with the A/C or defroster "on". This can be caused by the lack of mileage needed for the EEC IV processor to
learn adaptive idle strategy.
ACTION:
If "cold" start-up stalling still exists after accumulating 500 miles (800 kilometers), install a new level EEC IV processor. Refer to the
following application chart for additional service information.
