Did this video help you?

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

boulderburwell: Your coil packs are electronically controlled which if there is a power surge in a worn out coil pack that could cause the issue 

Erik Obert: Cylinder misfire. It happened to my truck, replaced the spark plugs. Usually it's 8. But since it has been doing that for quite some time. It's best to replace all the spark plugs. My truck has been better since, but now it's doing it again occasionally. I think it would do that again after replacing those plugs only in my theory, it would have a misfire because of the way you would accelerate your throttle. (for example) after a complete stop, you petal to the medal right away by flooring your gas. If it's not that what would cause a misfire, I would love to hear how it would. Thank you.

Evan Mitchell: Ford is very sensitive to the type of fuel you use if you are using unleaded try using premium if that doesn't work after of using premium for a week or two change your plugs and coils and the mis firing should stop after all that

Cassie Bargoil: I have a 2007 Expedition with the 5.4L Triton V8 that has been doing the same thing for 2 years now! It finally a few months ago gave us a misfire on cylinder 2 so we replaced the coil. Last year we replaced the torque converter because they thought that was the problem. It will hesitate and jump around in high gear mainly under acceleration. So we replaced the fuel filter. Still hasn't fixed the problem. In order for the engine light to come on it has to hesitate and jump around for a at least 2 minutes before it will flash. It isn't missing in idle. Other than that jump or jerk in high gear my car runs fine. Also runs better in cold weather than it does in warm weather. If it's above 50 degrees outside it runs like crap. We are already $500 in to trying to solve the problem. Just like yours it has plenty of power, runs like a top, just has that has jerk under load. We are going to replace the spark plugs and see if that changes anything. Also, like yours it started doing it at around 80,000 miles, it didn't do it very often maybe once a month, now at 120,000 it does it every time you drive it unless its super cold outside. Through my research this seems to be typical of this motor and my understanding is FORD knew about it. There has also been a class action suit filed against them, because FORD posted a service bulletin for their dealerships on how to fix the problem but intentionally concealed the issue from customers. I'd keep an eye on that.

WE2TECH: you say turn up the volume to hear the engine and 5 seconds later you have that loud ass bullcrap music playing freak you im trying to fix some crap and your trying to kill my only speaker thanks buddy

Logger870: I have a 2000 ford f-350 5.4L triton v8 and mine has recently had this problem as well, i havent driven it in a few weeks and it was fine then but now i noticed it has a rough idle, the exhaust smells like unburnt/raw fuel and under acceleration it is really bad, it shakes the truck and there is heavy hesitation under load. Now idk if its a bad injector, a dead spark plug, but i just started to really notice it today and today was the first time i used it in weeks. It has 139,000kms, recent oil change and new rotors and calipers, and it hasnt been driven in a while, and im wondering why its suddenly misfiring. Its a 5 speed manual. Btw its barely been off highway and it was babied by its previous owner and myself, anyone with any ideas what could be the problem? 

sole king: Really great vid! My truck had the same problem but it's all fixed now thanks to you man.

John Broden: When it start to mis hit the gas hard then your engine light will come on it the plugs or the coil pack 

cole morgan: My truck does the same thing! If i stop and stomp it. It revs really high and has an acceleration hesitation... even if i go to pass someone at about 40-60 mph it wants to rev high and backfire so i have to get out of it.. what needs to be done? 

notredame2191: It's the ignition coils almost every time

Slim Man: Ok, so I am going to get the plugs changed in hope that it fixes my baby, but it is kinda what he is saying. Only thing is when I am just driving normal and like 55-60mph, the motor will sputter, and jerk. Not when I get on it, but just driving like normal, with normal acceleration. Little help to make sure I am heading in the right direction plz!!!!

De'Von Bouldin: with all this technology, we should have a car that tells/shows us EXACTLY what's wrong with it.

"warning: replace spark plugs"

Ben Noyes: turn ur music off, pickle

Justin Johnson: I need help guys I have a 1999 f150 mine was shaking roughly as well changed the plugs and coils driving better but check engine light still on? When I'm just sitting in the truck I still feel a slight jerk sometimes I was told it was my fuel injectors my question is is it possible for all 8 injectors to go bad? And what do I need to do?

Cody Deadmond: I like that cluster man

Travis Bacon: Hey I just bought an 2007 F150 and I have misfire when lugged or when it drops down to pass someone on highway. I tried to pull wire off each coil to hear if it changes the sound of motor and it doesn't. What do you suggest???  PLEASE HELP

Trey Davis: Its your foam seal on your air filter holder

malcomboy: I just did the same thing in my 07 King Ranch, replaced all 8 ignition coils and spark plugs with the Motorcraft SP-515 updated version spark plugs.  Misfire in my #7 spark plug.  So just replaced all of them.
