These codes come up after I have driven down the road about 5 miles. It goes off again after sitting a while. When you drive the truck after it shifes out of 1st gear going in to 2 and 3 gear it chockes out and try to die. But if I keep putting on the gas I can get going again at about 55 or 60 it runs smooth. I have changed the knock sensor and the fuel pump. Cleaned the egr. New plugs and plug wires. New distrubitor and rotor button. HELP

Check the EGR valve and the knock sensor again -disconnect the battery for a few mins-and if the codes will come back
