Recently its been showing a ranch light know for throttle body issues code p2111 and p2104. This causes my car to stall in the middle of traffic especially on the highway which is a huge concern.

The engine surges and the car lurches periodically - normally after the engine warms up. It surges when you take the car out of park and place the selector in drive or reverse. It also surges and lurches when sitting at a light and removing pressure on the brake pedal. The potential for property and personal damage are substantial. Ford should be compelled to issue a recall. There are many complaints regarding this defect on other websites and nothing seems to be moving in the direction of resolution. Please help.

The vehicle while in drive or reverse accelerates to almost 2k RPM causing a jerking motion at any time when you turn the steering wheel. Could potentially cause an accident if in traffic and the car jerks forward.

Started my vehicle as regular, as I shifted into drive my car jerked and my message screen read "failsafe engine mode". I cut the car off and restarted it. The same outcome of it jerking and accelerating on it own.
