SOME VEHICLES MAY EXPERIENCE THE FOLLOWING SYMPTOMS AT AMBIENT TEMPERATURES BETWEEN APPROX. 14 TO 25 DEGREES F (-4 TO -10 DEGREES C) AFTER A COLD START:•UNUSUALLY LONG CRANKING IS NEEDED TO START THE ENGINE•ENGINE IMMEDIATELY STALLS AFTER START UP; CAN BE RE-STARTED.•ROUGH IDLEIF FUELS CONTAINING HEAVY COMPONENTS (I.E. SUMMER FUEL) IS USED DURING THE COLD SEASON, THE A/F RATIO MAY BECOME LEAN DUE TO LOW VAPORIZATION. THIS MAY CAUSE THE ENGINE TO MIS-FIRE. TO ELIMINATE THIS CONCERN, THE PCM CONTROL LOGIC HAS BEEN CHANGED.
