Would a size 18 shoe be a problem? Seriously, I wear a size 10.5 shoe but let me say a few things.
I went outside to duplicate the problem by purposely putting my foot between the brake and the gas pedals.
It's not impossible but it sure feels awkward. True, both times it has happened I had my foot on the brake.
I really hope that is it, I've been driving cars for 36 years and this is the FIRST time it has happen to me to place my foot between the brake and gas pedals (if that is what i did)
God knows how many times I've ever jumped in the car in a hurry and not do that!
A month ago I was creeping up to the McDonalds pay window, had just stopped and handed my money to the cashier when the engine began racing!
Yesterday, I was backing out to move the car over because I had my kid's car blocked in the driveway. Wasn't in a hurry then.
I'm going to pay more attention to my foot placement and I'm not going to let anyone else drive the car for a while.
I went to the dealer this morning (Monday is a bad day to go) i talked to a rep and they said they would connect the car to the computer and run some diagnostics, check for codes and connect a data recorder and drive the car around for 5-10 miles. Unless they can duplicate it they won't do anything. I'm taking the car back there next week when I have day off and let them check it out. In the meantime, I'm going to call the NTSB and file a report just so I have an official record on file.
thanks for the comments!

Called the NTSB, they won't take a complaint until the dealer has looked at the car.
I searched the NTSB for complaints and found...
Model: MUSTANG (and GT's)
Complaint Number: 10171025
APPLYING QUICK ACCELERATION IN ORDER TO PASS OTHER VEHICLES CAUSES THE THROTTLE TO STICK IN MY CAR. I HAVE APPLY HARD BRAKING AND TURN THE IGNITION KEY OFF TO GAIN CONTROL OF MY CAR. *NM
Complaint Number: 10166998
DT*: THE CONTACT STATED WHILE ACCELERATING FROM AN STOPPED POSITION, THE VEHICLE ACCELERATED FROM 50-90 MPH ON ITS OWN. BOTH FEET WERE APPLIED TO THE BRAKE PEDAL AND THE ACCELERATION STOPPED. THE VEHICLE WAS TAKEN TO THE DEALERSHIP WHERE THE PROBLEM COULD NOT BE DUPLICATED. THIS HAPPENED A SECOND TIME AND THE DEALERSHIP WAS STILL UNABLE TO DUPLICATE THE PROBLEM.
Complaint Number: 10155529
TOOK DELIVERY OF MUSTANG PREMIUM CONVERTIBLE (V6) ON 1/6/2006. DROVE HOME 17 MILES. WHILE ACCELERATING FROM A FULL STOP AND TURNING ONTO SIDE STREET, THE ENGINE APPEARED TO ACCELERATE AND THEN STOPPED IN THE MIDDLE OF THE TURN IN THE MIDDLE OF ONCOMING TRAFFIC. FORTUNATELY NO ACCIDENT OCCURRED. DURING SUBSEQUENT DRIVES, ENGINE APPEARS TO ACCELERATE FROM A FULL STOP BUT THEN STALLS. IF ACCELERATOR IS PRESSED QUICKLY ENOUGH, THE ENGINE DOES NOT STOP; HOWEVER, IT MAY EXHIBIT THE STALL A SECOND TIME. DEALER INDICATES THAT NO INFORMATION IS RECORDED ON COMPUTER INDICATING REASON FOR FAILURE. THEY CANNOT DUPLICATE THE FAILURE. NEXT STEP IS TO INSTALL A "BLACK BOX" TO RECORD EVENT ACTIVITY DURING THE STALL. THIS DOES NOT OCCUR WHEN THE ENGINE IS COLD. IT ALSO IS VERY INTERMITTENT BUT, IF IT IS GOING TO HAPPEN, IT WILL BE FOLLOWING A FULL STOP. I DO NOT FEEL SAFE IN THIS VEHICLE. THE FAILURE CAN OCCUR DURING A TURN ACROSS TRAFFIC OR WHILE MOVING STRAIGHT AHEAD FROM THE STOP - EITHER OF WHICH COULD RESULT IN AN ACCIDENT. *JB
Complaint Number: 10155220
DT*: THE CONTACT STATED WHILE EXITING THE INTERSTATE, AFTER DECELERATING, THE ACCELERATOR PEDAL WAS DEPRESSED AND THE VEHICLE LOST POWER. THE VEHICLE HESITATED THEN SUDDENLY SURGED FORWARD. THIS OCCURRED ON THREE OCCASIONS, THE DEALERSHIP WAS UNABLE TO DETERMINE A PROBLEM. UPDATED 5/2/2006 - EACH TIME THIS PROBLEM OCCURRED THE VEHICLE HAD BEEN DRIVING AT HIGHWAY SPEED FOR OVER 2 HOURS. *NM
Complaint Number: 10150456
2006 FORD MUSTANG EXHIBITING HESITATION UPON ACCELERATION ON FOUR DIFFERENT OCCASIONS WHILE PULLING OUT INTO TRAFFIC. FEELS AS IF CAR HAS STALLED THEN SLING SHOTS CAR INTO TRAFFIC. EACH INCIDENT NEARLY RESULTING IN ACCIDENTS. DEALERSHIP CAN'T DUPLICATE PROBLEM AND THEREFORE CAN'T MAKE ANY REPAIRS TO CAR. NO SENSOR ERRORS OR MESSAGES WHEN CHECKED, BUT OBVIOUSLY THERE IS A MALFUNCTION WITH ELECTRONIC &/OR SENSORS FROM GAS PEDAL TO ENGINE. *JB
Model: MUSTANG GT

LIKE YOU REALLY WANT TO KNOW IF YOUR RESTRICTING THE AMOUNT OF WORDS. *JB
Thats just 2006 models and only the last one is a GT (whats going on with the last one, replacing lifters and followers etc with 629 miles!!!) None of these are exactly what i expierenced but just wanted to make you all aware of these!
I'll let you know what the dealer finds out next week!
I am extemely hesitant to reply on this subject but my motivation for such is your concern of safety and not my desire to ease your (and everyone elses) mind somewhat....
I know you can swear that your foot was not on the accelerator, but consider the fact that the return force of the brake is much greater than that of the accelerator and because of such, it is possible that if your foot is depressing both pedals simultaneously - you may not feel the accel underneath your foot. Although electronic throttle puts control of the throttle plate in the PCM's hands, it can not and will not modulate the throttle unless three completely different and opposing travel signals from the accel pedal move together. It is virtually impossible for there to be three electrical malfunctions to happen at the exact moment in time and happen in a manner that makes the pcm think you have your foot on the gas. The system is actually too sensitive (Anyone ever had a "failsafe mode" event for no obvious reason?). The failsafe modes will become active if ANY of the tp, etc or app signals becomes out of a specific range even for a split second. Now, I really don't want to discount your concern. You should definately have this investiaged by your dealer. However, the previous poster is right in the respect that the dealer will likely not be able to duplicate the issue and will only have a VDR as a second option. A VDR is a Vehicle Data Recorder and is operated by yourself by pushing a button. This will record all the information the PCM sees during that time but it will require your ability to recreate the issue as well. Obviously this is not an ideal situation, but it is the only option if you want the dealer to take your complaint seriously, or make ANY type of repair attempt. They should remove your floormat alltogether as well. Just FYI, this is not something completely unheard of. All manufacturers deal with this regardless of the throttle contol, but it obviously becomes a sticky situation when it is computer controlled. Of all the people who have complained of similar issues, Ford has never had a confirmed case of self accel. All recordings sent back show that the brake and accel pedal move at the same time. Ever wonder why this only happens when you are braking and not any other time? It is due to pedal placement and the way you drive. I drive like that too, I pivit my right foot on my heel instead of lifting it completely off the floor and moving it over to brake. I have a size 12 shoe and have to be careful even in my manual 91 toyota because if I brake too hard, the gas pedal gets some and conseqently the engine will rev up sometimes during panic stops. Again, I wanted to give you the explaination your dealer will get when they call me about your concern and prepare you for the most likely outcome of your first visit. I hope for everyone's sake that the issue is handled maturely and seriously and I will look foreward to the result of your actions should you feel the need to post them. Good luck, buddy.
I believe you are referring to the problem Ford had with thier cars jumping out of park. One of my buddies almost got fired over that. It was years later when the problem was brought to the forefront that people finially belived his story. ...He did leave it in Park!
Vehicle: 2006 Ford Mustang GT and 1985 Ford T-bird 302
Location: Baytown, TX
RE: HELP! Sudden Acceleration !!!
it used to happen on my 85 t-bird but it would stop after it warmed up and there was some part on the TB that was messed up
I could get out of the car and it would hold at about 5500RPM then pop the hood and turn the TB blade away from WOT and it would stop but that problem was unrelated to this because it had to do with a vacum line and spring
You know I hate going to a dealer for service because they are always so busy and it's going to take a half a day or more where I'm just sitting there waiting. Anyway, I went early today (but not early enough) and saw a lot of cars sitting in line for the service dept so I just turned around and came back home.
There hasn't been any more problems for over a week and I'm paying attention to my foot placement everytime I get in the car. The more I think about it had to be me. I work as a troubleshooter in industrial electronics so I know how to think through a problem. Even if the output device that drives the actual throttle shorted, there would have to be protection built in to shut down the engine.
I'm going to wait and if this happens again I'm going to make sure where my foot is !!! I said earlier I've been driving for 36 years and never done that. Well, I'm also 36 years older !!!
If this ever happens again I'll definitely be at the dealer at 6 in the morning knocking on the door. I'll still drop in here occasionally with an update.
Now see I was all set to post something like, "Yes, I have heard of this problem! It is my medical opinion that your mustang is infected with *dum DUM dum* THE SUPER CHARGER VIRUS!", but then I started reading and decided that posting such a thing would be like laughing at a funeral...
Seriously though, why is it so hard to believe that this could be a real problem? I'll freely admit I know nothing about the PCM, or the fly by wire throttle control, but since the computer does more than just regulate the throttle control, some other system could be malfunctioning and causing it. Things like this happen in software all the time; some variable overflows into another variable, and suddenly your "0" becomes a "2+ billion". SHAZZAM, your car just went blast off. Turn car off, variables reset, turn car on, it's fine, until that same sequence of events triggers the overflow again. Yes, it could be human error, but humans built the thing, and ruling out a mechanical/electrical problem because in the name of a "failsafe system" isn't really ruling it out definitively, in my opinion.
Personally, I've never had this happen to me. Lots of other fun computer controlled things happen that I don't like, but nothing this severe. I have been in an Oldsmobile Cutlas Sierra that would accelerate on it's own (could ride 4 miles into town on hilly roads doing 60MPH without touching gas at all, and having to brake occasionally); turned out to be a faulty part, i forget which one.
Good luck with trying to get it diagnosed and resolved.
Well you are not alone. You post to warn other people of the problem. Then you get all the negative responses, your shoe size, you had your foot on both pedals, etc. Well, here's my horror story.
This past Saturday my wife and I drove to a buddy's house to see his Xmas lights. Upon leaving I backed out of his driveway, and put our 2006 GT Premium Coupe into drive and had the wildest 10 second drive of my life. You know you cannot shift into reverse or drive without having your foot on the brake. So, I put my foot on the brake, shift into reverse and idle backwards. With my foot on the brake I shift into drive and immediately the car goes full, wide open throttle. Well, the brakes did nothing to slow the car down. I put my left foot on the brake also and it would not stop. We were on a narrow street (residential) where I had to make a left and then a right to get out. I could do nothing but steer the car and try to avoid hitting anything. Well, I missed the first house
drove up on the lawn of the second house, hit the rear of a Caddy in the driveway, then careened across the street into a driveway with a carport. I hit the garage at the rear of the driveway, which
eventually stopped the car.
We filed a complaint with Ford, and filed a complaint with the NHTSA. The car is in the body shop right now. As for the negative responses, I hope I get to see their posts when it happens to them.
