2005 Mazda Tribute fuel system problems

When approaching a 4-way intersection during daylight hours, the light turned yellow then red. I tried to stop by pressing my brake pedal. My vehicle did not slow down, but continued to accelerate up hill. I pressed as hard as possible but my vehicle went through the intersection and I ran into the side of another vehicle. I was originally going about 30MPH and when I hit the other vehicle, I was going about 25MPH. My vehicle stopped after hitting the other vehicle but continued to rev higher.

While accelerating, the accelerator gets stuck and the car suddenly slows down to a crawl. Driver has to pull over and pump accelerator in order to get it unstuck. Checked with dealer initially and called mazda today january 8, 2014 to ask if there have been a recall. Was told, no. In the past, had to take car to mechanic and left it to be test driven in order for mechanic to replicate problem. Mechanic found the problem and cleaned accelerator. Problem continuous sporadically.
