Triton 2005 revolutions are lowered.

Friends, I have a problem with a 2005 Triton, the revolutions are lowered and it is killed, I put elo Scanner and marked many codes, I already changed TPS, gasoline pump, I check some sensors, but I do not know what to do, you continue to kill ... You can give me some idea. I am not an expert in this type of truck is a 2005 Triton 3 valves, 5.4.
I hope someone can help me. I am new in the forum.

Friend I saw a vehicle that had some similar symptoms ... They took him to the Scaner and did not throw anything later I went to see it and lacked a hose that was emptied in the distribution membrane ... Check well detailed in there you can be the solution of your problem ... I hope it serves you something.

Thank you friend, for your intention, but it no longer has a distributor is electronic throat ... Also look in several sensors. Thanks anyway.
