2007 FORD F-250 SD Engine And Engine Coolingenginediesel Problems

AFTER ABOUT 28,000-30,000 THE TRUCK WOULD SEVERELY BUCK/JERK/HOP WHEN TOWING A LOAD. THE PROBLEM OCCURS IN THIRD GEAR MOST COMMONLY. UPON ACCELERATION UP A HILL, THE TRUCK HAS AN EXTREME BUCK. THE RPMS RAISE AND LOWER UP TO 400 RPM. FORD HAS DETERMINED THIS ACTION TO BE NORMAL. THE ONLY WAY I HAVE FOND TO STOP THIS, IS TO LET ALL THE WAY OFF THE ACCELERATOR, AND THEN TRY AGAIN. THE TRUCK WILL THEN START THIS AGAIN, IN WHICH I HAVE TO LET OFF.

EVER SINCE WE PURCHASED OUR 2007 FORD F250, (WHICH WAS DELIVERED NEW IN SEPT. 2006), THE THROTTLE HAS FAILED TO RETURN PROPERLY. THERE ARE INTERMITTENT DELAYS OF UP TO 10 SECONDS BEFORE THE ENGINE WILL RETURN TO IDLE AFTER RELEASING THE THROTTLE PEDAL WHEN DRIVING THE VEHICLE. WE HAVE TAKEN THE TRUCK BACK TO THE DEALER OR CALLED THE DEALER EIGHT OR MORE TIMES COMPLAINING ABOUT THE PROBLEM SINCE DELIVERY. TO DATE, THE PROBLEM IS NOT FIXED. *TR
