Consumer Description

NOTICEABLE LAG DURING ACCELERATION. MOST NOTEWORTHY INCIDENT INVOLVED PASSING AT FREEWAY SPEEDS, ENGINE BOGGED DOWN AND CAR FELT LIKE IT WAS ABOUT TO STALL. HAVE NOTICED THIS A FEW TIMES SINCE AS WELL. WE ARE IN MONSOON SEASON, HAVE HAD RAIN AND HIGHER THAN NORMAL HUMIDITY. HAVE ALSO NOTICED WHAT FEELS LIKE DELAYED AND HARD TRANSMISSION SHIFTING. FUEL CONSUMPTION/MILEAGE SEEMS TO BE AFFECTED. (WAS GETTING 17-23MPG WHEN TRUCK WAS FIRST PURCHASED IN MARCH 21013, AM NOW AVERAGING 13-15MPG). HAVE ALSO NOTICED VIBRATION/SHUDDERING WHEN ACCELERATING FROM A STOP LIGHT OR SIGN, AND DURING DOWNSHIFTING. VEHICLE IS CURRENTLY IN SHOP AS CHECK ENGINE LIGHT CAME ON ON 8/26/13. FORD IS PERFORMING A COLD-SOAK(?) THE CODE THAT THEY PULLED FROM THE VEHICLE WAS INDICATIVE OF A MISFIRE BUT THEY CANNOT DETERMINE WHAT IS CAUSING THE MISFIRE AT THIS TIME. *TT
