Ford Mustang GT jerking problems

The electronic throttle body and electronic throttle sensor were sending my car into "limp mode", and very nearly caused two accidents before I could have the issue diagnosed and repaired. The first instance of "limp mode" came while I was driving home on the freeway in commute traffic. It was warm, traffic was erratic stop-and-go, and I had the AC on. After a period of coasting at idle, traffic opened up; but when I tried to accelerate the car staggered and nearly stalled. I thought it was due to heat and the AC. The car then jerked forward before running smoothly again. The second time, I was on my way to work, again in freeway commute traffic. Traffic was at a stop for several minutes, and then I heard a news report that there were accidents ahead. I moved over to the 4th lane of 5, in preparation for exiting at the next off ramp. When I tried to pull out and speed up into that lane, the car again staggered and then stalled; I managed to re-start it and get moving again as a truck came racing towards me, with the driver hitting his brakes and horn. I barely avoided a crash.

After coming to a stop, I try to accelerate and the car stalls and jerks into gear. I was told that the throttle was dirty. I had it cleaned and got a new air filter but was still experiencing the same problem. The next step was to replace throttle sensor. The mechanic advised to check the recall list and I several people who experience the same problem with no help from ford. I saw this site and decided to post.

On august 13, 2013 at 1:45pm while driving to a car dealership in elgin, il, my wife and I were driving north on rt59 which is a 45 MPH zone. My pressed the accelerator pedal and the car started to sputter and hesitate. She pressed the pedal a little more and the car just took off by its self. Before we knew it, we were traveling at 70 MPH though a large population area. My wife was terrified and tried pressing the brakes to the floor but they only slowed the car a little. I told my wife to tap the accelerator pedal to see if the speed would reduce. It only increased in speed. I told my wife to tap the pedal again. The car did not slow and she was still unable to slow the car with the brakes. I told my wife to press the pedal harder. The car lurched forward and then began to slow down. My told me last year that while she was driving the car that it did the exacted same thing, but I didn't understand what she was talking about until I experienced it myself. My wife was terrified and it scared the [xxx] out of me as well. The car is showing no check engine lights or service engine soon lights. This malfunction could cost someone their life and needs to be addressed. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

2005 ford mustang gt convertible. This vehicle has an automatic transmission that when accelerating will sporadically shifts from first to second gear with a extremely rough gear change. The rough gear change jerks the car forward with enough force to strain the passenger necks and accelerates the car unexpectedly which can easily lead to a frontal crash.

Dt: when the consumer would apply the brakes the steering wheel would jerk out of consumers hand. The steering would pull toward the left. This occurred at least four times. The consumer did not have any accidents because once he let off the brake it was fine. The first time he took it to a dealership they did nothing to the vehicle. The second time they greased a bushing. The third time they told him it was to dangerous to drive ,and that they would have to wait for a part. Also, they told consumer that there was something broken in the steering area, but they will not tell him what it was. The vehicle has not been fixed as of yet, it is currently at the dealership. Consumer has not contacted the manufacturer as of yet.

2001 mustang gt with automatic transmission displays an extended-hard-grinding shift from 1st gear to 2nd gear especially after making a right turn. Also when cruising at normal highway speeds the transmission makes a hesitant clanking noise which jerks the car slighlty if one's foot is taken off the gas pedal for a few seconds and then clank again when speed is resumed when depressing the gas pedal. This problem began soon after purchase of the new car and still exits now with 48,000 miles on it. * cb

Computer controlled idle defective, idle surges unpredictably. Occurs mostly when stopped. Idle fluctuates between 500 and 1000. Sometimes will stall and other times will lurch forward against the brakes. If A/C is turned on, the condition is worse. Car has been returned to dealer and they "can't" fix it because it is a computer controlled problem.
