While driving down the left lane of the sawgrass expressway, a very busy highway between ft. Lauderdale and miami, I lost all throttle response. The wrench light came on the dashboard and I went from 60 mph down to nothing by the time I was off to the side of the road. Cars behind me were obviously braking hard to avoid smashing into me. I turned the car off and was about to call aaa, but the heat index that day was around a million degrees so I turned the car back on. The throttle response had returned so I cautiously limped the car back home in the right hand lane the whole way. I thought it was some freak computer glitch until it happened again going to the store the next day. I called the Ford dealership and before I even got the problem oout of my mouth the service tech said " it is your throttle body. We see this all the time. It will be about $800 to repair". If the techs are aware of this problem and it is all over the internet with people complaining about dangerous situations the have been placed in as a result, and there is already a recall for the same problem in other Ford models, then why hasn't the NHTSA done anything to force Ford to recall for the same problem on the Mustang? does someone have to die first? has somebody died because of this?.
