Vehicle Shudder problems of the 2010 Mercury Milan

I was driving down the highway traveling at approximately 60mph when the car suddenly stalled and I was not able to accelerate. The wrench light came on at the same time as well. I turned on my hazard lights and was able to coast to the shoulder of the road. The car started to shake a lot as it slowed down. I turned the car off, and was able to start back up again. The very next morning while traveling a 50mph on a different highway the same thing happened again. I took it to the dealership to have a diagnostic run on the car as I had no idea why it was stopping. As I was about to turn into the dealership traveling at 25mph it stalled again. The result of the diagnostic test was there was a code stored in system of the electronic throttle body. It was giving a code for being stuck open when it should not have been. It was a failed component. . Read more...

It first occurred when I drove on the highway and it shut off when I was at a stop light. After waiting a minute I turned the car on and it started. The next occurrence happened when I was driving my vehicle on the highway going 60 mph it started downshifting until it stopped at 0 mph and made kind of a tutting noise until it stopped. The maintenance light came on and the car started shaking. Afterwards the check engine light came on. I turned off the car and waited a minute and tried to start the car up after. It took about a minute for the car to start up and eventually started up. I went about 35-45mph a couple of miles down the road and the car downshifted again and shut off. The car started shaking again. I then waited again and started it up again. I drove the car into a neighborhood driving 20 mph to park it up and it get it out of the way from being on the highway.

On 7/26 the car lost all engine power on the highway and the wrench light appeared. After coasting to the side of the road, the car shakes until put into park. I shut the car off, wait a few seconds, restart and the wrench disappears as well as the shaking. I am able to continue as if nothing happened. Three more times it happens that day. A few days go by without incident. On 7/31 it occurs again three times following the same travel route as the days before, but in a 35mph zone insted. On 8/2 I take the car to a mechanic who diagnoses it as p2111 (faulty throttle body) and says he can't get the part due to a national back order. My faulty part is 9l8e-9f991-bc and I have called and looked online at several Ford dealers and am also told the part is on national back order with no firm eta. The car is not drivable until this is fixed.

Wrench light came on and car started shaking and sputtering and would not advance and I almost got rear ended. I feel this is a serious problem and needs to be addressed. Also the engine light came on. Thank you.
