truck trouble I have an 03 silverado with a 4.3. I can get it to start by holding the pedal to the floor, but after about 30 seconds it starts to idle rough and dies. Truck has had new plugs, wires, cap and rotor over last summer. Any ideas?

Cat may be stoped up, take a compression gague and plug it in the o2 sensor hole in front and behind the cat and see how close they are. If the back is a lot lower, there's your problem
