2007 f150 5.4L xlt so my dash panel went dead last year so i changed battery and alternator and my check battery light still comes on and off and i can feel my engine like loosing some power so it seems its been almost a year and its still on i have changed out 3 alternators and im getting really tired of doing this over and over again i have hooked up 5 different types of engine diagnostic analyzers and 3 couldnt read computer other 2 said there were no problems detected is there anyone who can point me in a direction as to fix it i dont want to keep going threw with this problem

 

Most often if you include NO info at all about year, engine or other pertinent details it greatly limits the effort people are willing to put out to help you. For MOST people 20 questions is NOT a fun game.

 

well its a 2007 f150 5.4L is that better for you forgot to be politically correct
