    Fords VEHICLE SPEED CONTROL problem

    Because there isn't any problem. Other than the one that the recent poster invented.

    • I hope youcan read there are many more just like this.
      summary:
      the accelerator and brake are so close together on my 2008 ford f150 that i have
      on occasion accidently pressed both the accelerator and brake pedals at the same
      time while braking. The first time it happened i did not know what was happening. The
      engine was revving up as i was applying the brake, so i applied the brake harder and
      the engine continued to rev higher until the truck lurched forward. This caught me
      by suprise and my foot came off the brake and the engine revved down. I realized
      that my foot had been on the accelerator the same time it was on the brake. Since
      that first time, i know that if the engine starts revving while i am applying the brake
      that i have my foot on both and can angle my foot to the left to remove it from the
      accelerator while still keeping my foot on the brake. Even so, one time i just missed
      hitting the car in front of me while "stopping". Ths seems to me to be a dangerous
      design. When the engine begins revving for "no apparent reason" one tends to panic
      and steps harder on the brake which makes the problem worse. I think there needs
      to be a recall on this problem.

    • On my F-150, the throttle system averages throttle input and sends that out to the stepper motor that controls the throttle plates. The sense from driving it was a lack of feedback. At one point I did for a moment have the truck accelerating when I slammed on the brakes before the ECU backed off the gas. I didn't think the issue was dangerous, just stupid. My solution was to install a tuner and reduce the dwell on the throttle position to zero. The result is the truck drives normal with good feedback.
