Steady decrease in power and mileage - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Recently, I have noticed that my truck is getting worse gas milage. The other day, I decided to give it a full throttle punch (fully up to temperature) and the truck fell on its face and then reved up, not really going anywhere in the process. I also noticed that the tach didnt really move either (it used to fly). I took all of the plugs out and they were all in good shape. I took the distributor cap off and it looked alright also. I did notice that the graphite piece in the center looked a little flat. The fuel filter is also clean. What else should I look for?
