2006 Ford Mustang acceleration problems

Filed Jul 31, 2023 · Acceleration, Fuel system · MO

While driving the car goes into limp mode randomly causing the RPM’s to fall. There is no power to get off the road safely and has almost caused an accident numerous times. I have had Diagnostics ran and the mechanic has no clue what’s causing this. Ford forums are full of these mustangs doing this. It is a huge safely risk!!!!

On June 18, 2023, my throttle unexpectedly stuck open after intentional acceleration, causing the car to continue to accelerate uncontrollably after releasing the accelerator pedal. The engine continued to increase RPMs and speed. After using all of my leg strength to apply the brakes to fight the uncontrolled acceleration, the throttle unexpectedly eased up and returned to normal. This was the most frightening instance. On two other occasions, I noticed similar uncontrolled acceleration that seemed to correct itself immediately after shifting, where the tachometer approached 5k RPMs. I have not had the vehicle inspected, and there were no warning lamps, or other symptoms prior to this failure.

Car suddenly went into limp mode, no reason. Just started it up one day and it just did not want to move. No one knows how to get it out of the mode. Many mechanics have tried with no luck. Now a mechanic says I have a faulty computer. 3 years of it acting this way.. Computer diagnosis showed many things messed up, even after replacing all of those (and I am sure some were uneeded) the car is still in limp mode, has no power at all and has been basically down for 3 years. Beautiful lawn ornament but it being all I have left of my late husband, I'm not happy it just sits there. No mechanic wants to even touch it!

Pcm module/crash data report says that the throttle position sensor went to 100% with accelerator at 60% and then the throttle stayed wide open until accelerator pedal was released to approx 23% percent. Why is there a 40% difference in the PCM data from accelerator pedal position to the throttle position. At the trial a guy from ford said this is normal and the throttle is designed this way. My husband is now on his way to prison. Is this true and can anyone help or advise us.

Some years prior to this incident, the cruise control would cause pulling of the car. What I mean by this is that the vehicle would pull forward as if someone were towing it from the front. This would take place after the cruise control had been used minutes or hours prior to the vehicle being shut off. Once the car was turned on again, even an hour later, would cause the car to maintain its speed (usually 10 MPH or 15 MPH) until the brake was pressed even though the cruise control wasn't activated. This was supposedly "fixed" by ford through a $600 "repair" of the "computer" that controls the throttle (I have documentation to support this repair). I was unaware of this site. So now I am reporting the following terrifying incident. This 2006 ford mustang, about 2 years prior, had its cruise control on when all of a sudden the vehicle accelerated from 40 or 50 MPH to 60 to 70 MPH. The brake slowed the car but the revving was out of control. Luckily I was on an open highway around 10pm but had to drive into a gas station (luckily nothing happened) and slammed on the brakes as the engine revved hitting the upper rpms. I had to shut off the car with the ignition (leaving it in the park gear and pressing the brake, mind you!) and when turned on the car again (now in park), the car again, dangerously revved. I thought the engine was going to blow out. I shut off the car again, parked still at the entrance of this gas station. I waited some minutes and turned the car on again, sweating profusely as you can imagine, and the car was completely normal. I was convinced this had to do with the cruise control. I had aaa tow the car home and the next day I took it to ford who claimed they had never heard of such a thing. They checked the computer again and gave it an "update". I never used the cruise control again as you can imagine and no problems with the rpms or acceleration.

On monday february 24 2014 at around 12:45pm, I was on my way home from work. I was sitting in my 2006 ford mustang gt in bumper to bumper traffic due to construction on the grand central parkway(queens ny) heading towards the van wyck expressway(east to brooklyn ny). As traffic started to move up slowly, I had pressed on the gas pedal to move forward and without hesitation the car jumps from 7 MPH to full throttle. Even when I had applied the brakes ( I felt the brakes on the rotors but it didn't stop) the vehicle had stayed stuck on full throttle and had struck the vehicle in front of me. It bounced off the 1st vehicle and it was at this point I had placed both feet on the brakes, to the point where I was standing on them with my head hitting the roof of the car. The car proceeded on (still in full throttle and brakes applied) and smashed in between two other vehicles further up and after that collision thats when the car finally had came to a stop. I never heard or seen any vehicle take off on its own like that. Two days after the accident I had asked around on facebook on several mustang enthusiast/club pages and no one has heard of this happening. A week later my insurance company totaled out my vehicle and left me with no car and now I'm left to pay $3000 dollars difference on my loan and $500 to my insurance company. I also asked on ford's facebook page and I was given a number from a customer relations representative. I had called ford and they said they never heard of this and "what will I like to do with this?". A friend of mine told me about car complaints.com and I came across more than 20 complaints for the same problem. I also was told recently to check this website to file a complaint. I loved that car and that whole situation left me depressed and frustrated.
