My 1999 Windstar has sudden acceleration while in bumper to bumber slow moving traffic. It will all of a sudden accelerate forward while your foot is not on the brake or on the gas. We have taken it to three Ford delearships and are unable to get it fixed. We have been told this is normal with Fords and the computer shows no problems. This has been an ongoing problem and I am concerned about the safety of my family and myself while driving this vehicle. The transmission has already been replaced in may of 2000. Thank you!.
During shifts from 1st to 2nd gear with the engine at idle, at approximately 5 mph, the engine surges during the shift. As a result, the vehicle suddenly accelerates to approximately 9-10 mph. This has caused several near-accidents and panic stops in parking lots and stop-and-go traffic. During normal acceleration with a partially open throttle, this problem does not occur. The vehicle has behaved in this way since it was new.
