2003 Toyota Camry fuel system problems

On sunday, august 31, 2014, at about 1:00 pm, I was leaving the church parking lot after the service at san martin de porres catholic church. I was in my 2003 toyota camry with my friend (name provided on request). I drove from the lower level parking to the upper level parking lot where the exit is located. I was going approximately 5-10 miles per hour. We were coasting toward the exit when all of a sudden the car revved up really loud and accelerated/sped through a short street that feeds the parking lot.

On october 24, 2012, I parallel parked my 2003 toyota camry on the street. The car in front of me was leaving, so he asked me to move back a few inches so he could get out. My car was still running so I shifted the car into reverse, and as I began to take my foot off the brake pedal, my car accelerated backwards at a very fast speed into the car behind me.
