David Tennis: My truck Is worst when I hit the throttle it spits and farts all over the place replacing coil packs and spark plugs in the morning

Juan Casas: I had the same problem on my 07 King Ranch... Problem fixed thanks bro....

Robert G: Turn the music off jerkoff

livalittle100: 5.4 is a steaming pile of crap.

lincolnlz00arturo: I have the same problem. Replace spark plugs. Coils. And no luck. Also i don't get a single code from the ecm. If you got the solution please posted. Tankx.

lincolnlz00arturo: Did you ever figure it out what it was?

Pietsch Farms: Hey man, I have a 2006 Ford F-150 fx4, my first truck just bought it about 2 months ago. I am having this same kinda problem misses every once in a while on accelerations. When yours was missing, did the engine light blink or flash for a while and shut off every once in a while? Mine does it every once in a while. Thanks man! Nice truck. I wish I had the lariat, but I wanted a 4x4 off-road package so fx4 was best for me. Thanks man. Please get back.

Alan Gross: Mine has 87,000 and it's startting to misfire, so I've got an appointment with a local mechanic that I trust, to change my plugs. This is a $500 - $600 job.

John Moore: Maybe turn down your freaking music when making a video?

Earl Guyton: Sounds like a hesitation on acceleration issue here.  I am a master mechanic with 44 yrs experience here.  Heres the list I would go by or start with
1.  This is something hardly no one ever looks at first.  Battery cable connections!  Not only at the battery but at the ground connection at the frame or engine block.  The feed from the wire from the alternator to the battery.  Which can show charging of 14 plus volts but has a weak connection which causes delay at acceleration!  Those coils and plugs and electric fuel pump can only work as fast as they are all fed juice!!  But no one ever thinks of this!  Your coil plug connectors are next! 
2.  How to tell if your coils and plugs are okay.  Have engine idle then accelerate to 800 rpm and if it levels out and runs straight then the coils and plugs are good!  Meaning plugs and coils don't temporarily be bad and get good back and forth.  They either fire good or they don't and if they fire good once per day its because of fuel or slow electrical
3.  If either one or two did not correct it I would test my fuel pressure.   No matter if your vehicle is a 1920 or a 2015 it can only perform as good as the battery connection and alternator source.  I put double battery grounds on most all my vehicles.  Buy two small alligator clip and get a one foot length of wire about the size of a wire that's in your headlights plug and clamp the gator clip to the battery ground and other end to a good metal part of the inside of fender or even the frame and this strengthens your source for electrical.  Also clean your connections on top of your gas tank folks!

AllKind808: Ummm maybe turn down the music some?! I turned it up to hear the noise your truck makes and and a speaker full of blasting whatever that was.... 

Alton Lynch: it's not the spark plugs, it's the distributor, the pickups in the distributor. your truck will quit all together before too long
