04 f150 4x4 v8 3v 5.4 issues
 

well i bought the truck 2 moths ago and am just now finding out all the issues one big issue is it sounds like a small diesel and it drives me crazy another issue is when im on a hill it rolls back and the 3rd issue is that when im going about 40-50 going up hill still accelerating it makes a sliping feeling i was told it might be bad plugs im hopeing its not the tranny MY TRUCK HAS 142000 MILES ON IT AND I JUST GAVE IT AN OIL CHANGE CAN ANYONE TELL ME HOW TO FIX MY ISSUES PLEASE THEY ARE DRIVING ME CRAZY

put new plugs in it first....hope you have access to a rotunda plug tool, if they are the only plugs i got a feeling your gonna break some...if the tranny is slipping, which is possible with that kinda mileage, a rebuild is in order.

With that many miles,you will most likely need the rotunda tool.Snapon.com has them for about 100bucks.I got mine thru the snap on guy who delivers to my friends shop.And for the small diesel sound,do a search on here for that and you will find out why.For the most part the sound is normal.Mine always makes that sound and its normal.Just the cam phasers.The first time i head the sound i posted on here about it and took it to 4shops and all said the same thing.Normal sound and also on here when i posted about it,normal.Just get used to it.If its slipping then attom is right,time for a rebuild most likely

make sure to follow the tsb exactly if you are changing them plugs yourself

I started using Mobile1 Synthetic oil and Ford oil filters and my Diesel sound went away. Worth a try.

With that many miles count on broken plugs and a trans rebuild. Just facts of life with ANY vehicle... well not broken plugs.

well i dont think its sliping cuz it dont do it all the time and i was told it feels like its not sparking hard enought and its repeating but im not shore

i dont think its sliping but im not shore i think its just not getting a good enough spark

change the plugs and go from there.....if you take it it, brace yourself....
