Ford Mustang GT stalling 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.

The engine shuts off while driving after it heats up. This has happened several times in these last couple of months after purchasing the used vehicle. I took it to the dealership to fix. They replaced o2 sensors and I got it back last night and today I was driving on the freeway when the car just shut off on me again and the rpms dropped to zero. I was able to pull the car off to the side safely. I put the car in park and restarted it. I drove for about a minute or two and it shut off again, so again I pulled over and restarted the car. This happened about three or four times before I was able to reach my final destination.

To whom it concerns, back in october of 2013, I purchased a used, but very well kept, 2006 ford mustang gt premium. After a year or so, I experienced a problem that has left me afraid to drive the car. While slowly pulling into a parking space to park my car, I brought the vehicle to a complete stop, about to shift into park, while my foot was still depressing the brake pedal, the engine began to throttle up overpowering the brakes causing the back wheels to spin and the car to move forward. The harder I pushed down the brake pedal, the more it throttled up until it shot me up and over the cement wheel stop in front of the parking stall and onto the grass median at which time I turned the ignition off and slammed the shifter up into park. I was dumbfounded! I thought maybe somehow when my foot was on the brake pedal, it was also catching the side of the accelerator pedal thus making it seem like the harder I pushed down on the brake pedal, the more the engine would throttle up as well. I eventually shook it off and went about my day. Three days later, while pulling into my brothers garage and again, coming to a complete stop, it throttled up again the same way and my brother was standing in front of the car. He thought I was playing until he saw the panic on my face. He no sooner jumped out of the way when the car shot forward almost hitting him! This continues to happen never knowing when or where. It also has done this while just slowing down to almost a stop. I contacted ford who claimed ignorance and wouldn't do anything to help. Looked online for others having this problem and found hundreds of posts, even law suites against ford. I noticed people describing the accelerator sticking or going to the floor. That can't happen, there's no cable connection to the throttle. Electrical or computer defect in ford's drive by wire system. This needs to be fixed! Help!

The vehicle began stalling at low speeds, in traffic, at red lights/stop signs and while turning. Several very close calls to date. You must restart engine during a turn often with other motorists bearing down on you. There are many complaints on this site and when you do a search on the internet. The dealership is also aware of it because they tell you right away that you will need a $500.00 part to fix it and that does not include labor. I have also been told by a few mechanics that this used to be solved by replacing the idle air control switch,about a $40.00 part. That part is not offered with this year and model but it comes on the $500.00 part.

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.

Fuel pump breaks free from in-tank attachment point resulting in fuel level indicator malfunction and fuel starvation when corning, acceleration or abrupt deceleration. Causes unexpected lag in acceleration or vehicle may stall at inopportune times. Since original replacement of entire fuel tank assembly by ford the fuel sender in this vehicle has been repaired/replaced 2 additional times. Dealership noted that the plastic ring sender attaches to cracks and only way to repair is to replace entire fuel tank at cost of approx $900. Most recent 2 replacements occurred outside of extended warranty by a few days and ford refused to replace under warranty even though the vehicle had been parked over the winter and issue was not discovered until vehicle came out of storage after the extended warranty had expired. Repair had occurred in fall before vehicle went into storage. Each time fuel tank is replace ring cracks again, usually within 30-90days. This is a hazard as it is impossible to determine when the vehicle will experience fuel starvation or stalling, possibly resulting in accident or injury outside drivers ability to avoid.

2006 mustang gt manual transmission. Replacement of battery results in engine stalling with air conditioning on when clutch depressed.. The owners manual states on replacing battery the computer needs to relearn idle. This does not work at least not in a reasonable amount of time. The vehicle has been driven over a number of days with no improvement. With the air conditioner running and depressing the clutch either coming to stop or turning a corner the engine idle will drop far enough where the vehicle will stall resulting in a loss of power steering and power brakes possibly creating a dangerous situation. The vehicle ran correctly before the battery replacement and only has 22,000 miles. Googling this issue on the internet finds numerous problems which are identical of which owners of the 4.6l ford v8 (not just mustang) are reporting idle and stalling problems after replacing the battery and with the issue not resolving itself as the owners manual states resulting in either a computer reflash or throttle body replacement. This defect could result in a crash causing serious injury or death. Ford should recall affected vehicles and have the default idle setting set for a higher value so the air conditioner when engaged does not result in the engine stalling. The idle of engine is erratic with the air conditioner on since it is engaging and disengaging due to the low idle speed < 500rpm. By not using the air conditioner the idle speed will return to its normal speed of around 600 to 700rpm but still fluctuates slightly. Not being able to use the air conditioner is not acceptable, especially in the south east. The control feed back of the idle system is incorrectly operating with the air conditioner load on it.
