Truck idled and runs good. For it to have a little get up you have to put it to the floor. At normal speed holding the pedal still it looses power have to give it more gas to stay at same speed. It looses about 5 miles per hour in about 5 miles. Put a tune up already that wasn't the problem, I also changed the fuel pump and tank. If theres anything you can help me with it would be greatly appreciated. Thanks, Chad
