I noticed when warming up my truck that when I press the pedal and hold it that the rpms varies quite abite. It makes me think that the fly by wire system is sending different voltage from time to time at the same travel distance on the pedal. Their are also times when driving that it seems to take more throttle to get the job done than it should. At first I though it was not running as strong but now I think it is just not getting the voltage correct on the throttle position . Any one have any insight on this? This doesn't happen all the time while driving. Just every now and then.:confused:

techs, any advise?

interesting post, when my truck was fairly new, i lost power pulling one time, it semed just for a minute or so..maybe that was it..the wacko fly by wire, later, bc
