Question HELP !!! Big problem with Excursion

Im having a hell of a time with my Exc. Thought I had it fixed. Then it started again yesterday. I can press the gas pedal to take off at a light about a inch or so and the truck takes off like im pressing it to the floor.But im not moving my foot. And going down the road it will cut off and right back on and not a lot of power. Then it may not do this for 3 or 4 days. I just had a new brain box put in. I changed the fuel filter. I changed the pressure reg. behind the pump. After the brain box it did great for 5 days. Then here we go again. I have a big trip in two weeks and got to get it repaird. Thanks for help you can give.
Jack in Ga.

Is your fuel pump whining by chance? Mine did this every now and then until I changed my pump out.

Kinda sounds like you are having issues with the tps on the pedal itself. You need an autoenginuity or something like it that can read all the sensors on your truck.

I had the same problem. It was the pedal position sensor. Bought one at Napa and solved the problem, but the new sensor is a little fidgety. But when I did this, ford only sold the entire pedal assembly (very expensive) so aftermarket was the only way to go. Was still about $70.

X3 on your pedal sensor.
