When intering to tunnel my car suddenly speed up it felt like I had the gas pedle down to the floor. Even while holding the brake all the way down, this did not slow the car down much. There were no warning lights or check engine lights on then or now

Electronic throttle body p2119 code. All of the sudden losses power going into or out of traffic and the wrench tool light "lights up" it may go away by itself or not , "cut be scary" at times it has shut down in several instances on my own st or down the ave or another town etc... For no apparent reason it happens while turning or during acceleration at one point I had to wait for several minutes on the highway before starting the vehicle again and I get similar codes related to tbs powertrain and the fuel cap I noticed that when filling up, I need to stop pumping gas once it has stops automatically, without me topping it off not even once! And the light will most likely will not come on,it may go away by itself if not I erase the code.I clean the electronic throttle body last summer and it has run with no problems at all until now! Well a month a go! This summer I am getting lots of problems with the tbs again same symptoms like before all over again,except for the gas light. Thank you

Vehicle surges wildly at idle speeds in traffic. Vehicle stalls out while driving regular highway speed, surges wildly while driving, RPM spikes drastically while driving and at idle. Stalls and surges both while entering traffic from a stopped position and while driving at regular pace. Struggles to crank after fueling the vehicle. Spits and sputter and shakes while at idle....updated10/20/15

The car would not accelerate and the wrench symbol illuminated. I had to pull over turn off the car and restart it.

Driving from columbus to cincinnati around 1:00 am with my daughter, son and 15 month old granddaughter. The car lost all power leaving us stranded on the side of the road. As I pulled over the car began to shake, almost like there was water in the gas line. I turned the car off, waited a few minutes and then restarted. The car reset itself and luckily we made it the rest of the way home. Not too long after that, I was driving home from work and it did the same thing. Except this time, it would only go about 2 miles before it would quit again. This is a very dangerous issue. No only could I have been in an accident, but being stranded on the side of the expressway in the middle of the night with an infant was terrifying! I had the throttle valve sensor replaced and there has not been any additional instances of power failure.

On that date, I was driving home with my wife at approximately 2 pm. Suddenly, the car went off and the steering wheel went stiff. As I tried to move unsuccessfully, we went down to a slope of about 20 degrees. As a result, both of us had to be taken for emergency treatment for knocks, cuts and follow up checks. So far, it has cost us $16,497.00 and repair of the car us$6,853.00. There has been other events where the car suddenly stops and the steering wheel becomes stiff. But, I don t use the car in the highway but only for shorts errands and within the area where we live. Its been a nightmare. I have changed the throttle casing module, the restraint control module, I put a rubber stop on the acceleration pedal, etc. Again, out of the accident it has been over 4 thousand dollars in trying to fix the car.

Car felt like it was running out of gas. We pulled off the street and shut it down and waited,we had plenty of gas. We started it back up and it seemed ok, the engine and power train lights remained on. Since I had taken it in for the recall already and we were close to southgate ford we pulled into the service area I spoke to the service person and was told it would cost 600.00 to fix. I mentioned the recall, he said that was just for the software we then left an went to auto zone where they put their diagnostic tool on the car and the print out read there was a problem with the throttle body. Ford dealers refuse to replace the throttle body under the recall.

Coming to a stop at a red stop light and then trying to accelerate from red to green light at an intersection my vehicle went into limp mode, it lost power. It would not accelerate pass 10mph. An engine light came on as a orange wrench light. I drove as I could and made to auto zone. They plug in the hand held car computer and it gave the code p2119. Which stands for throttle body.

My vehicle suddenly stalled when I was driving and no matter how much I tried to press on the gas...it would not move safely. I was very lucky because this was at a traffic intersection on beechmont and eight mile. I proceeded to drive it to the enterprise parking lot albeit it was extremely slow and I had cars honking at me because of the lights on the intersection. The mechanic repair shop says it's the throttle body.

I had two separate occasions of my car stalling in the past three days. On may 1st I was traveling at about 40 MPH when my wrench light came on and the car stalled out. Fortunately there was a median right by me and I was able to hurry up and move over before the car came to a complete stop. On may 3rd I was traveling at about 35 MPH when the wrench light came on and my car stalled out in middle of the road. This time I was stuck in middle of the road but no one was behind me. I was able to restart the car and continue driving. If this had happened on the main road then there would have been a good chance of an accident occurring and harming me or my children.
