fx4 help!!
Hey guys am new here,
I have a fx4 5.4 2004 and sometimes it has a loss of power on the first and second shift...?The 3 mechanics just couldnt fix it.. they change the speed sensor.. the throttle body.. turbine speed sensor.. they reset the computer and its still the same.. like I said.. it just made it sometimes.. on freeway runs great.. feels like no power for a few seconds and then comes again.. Help! Dont know what else to do!

Try posting in the 04-08 section of the forum. Also give some more details like the miles on your truck, any modifications, what the mechanics said, history of maintenence, stuff like that. Good luck!
