Accelerator Stuck problems of the 2001 Chevrolet 2500

I own a 2001 Chevrolet 2500 hd crew cab 4x4 with a 6. 0 litre. On February 14, 2004, I noticed that the gas pedal was sticking when I first started the truck. It has continued to do this everytime I start the truck. Back in November of 2003, I was having my oil changed when the manager asked if I was having any trouble with the gas pedal sticking. I stated that I had not had any trouble with the gas pedal. At that point, he stated that almost every newer model Chevrolet truck he had seen has had that very problem when the mileage was around 75,000 miles. I now have around 75,000 miles on my truck now. It has become a safety issue. When I pick up my child from school, the gas pedal sticks when I am starting the truck up, and I have to press quite hard on the pedal. In an environment where children are walking all around, I cannot afford to have to punch on the gas pedal to get my truck to move. I would appreciate an investigation into this problem.
