Filed May 30, 2017 · Fuel system, Transmission · 130,000 miles · IN

At low speeds, when turning and when accelerating from a stop, the car will shake, lunge and then shut off. Sometimes it just shakes and hesitates and then keeps going. Sometimes it takes a while to get it running again. It always happens when the car is in motion. A couple of times this happened, the transmission error codes were displayed. I have had the transmission checked out and it was fine.

We have a 2005 ford five hundred. Two days ago, the car failed to respond when the accelerator was pressed, even as it was pressed to the floor. The wrench light came on and the car started lunging and hesitating in addition to not accelerating properly. This occurred while driving through a very busy intersection; thankfully, I was able to move the car with my two small children out of traffic. A diagnostic computer provided two codes - p2106 and p061b. This is not the first time the car has lunged; it has been doing this for approximately 1.5 years. It has repeated this several times in both drive and reverse. In most instances, the air conditioner was running at the same time; however, the car has lunged when the A/C was not on. The lunging occurs when the car is being driven or sitting idle (I.e., stop lights, preparing to merge into traffic). I have been able to avoid accidents by keeping my foot firmly on the brake and by creating a large stopping distance cushion. We contacted the dealer and were told the entire throttle body would need replaced, at a cost of over $530.00. We are now reviewing our options.
