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
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.
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?
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
sole king: Really great vid! My truck had the same problem but it's all fixed now
thanks to you man.
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
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?
Ben Noyes: turn ur music off, pickle
TheTerminator310: @mike caissie Yes, whenever it would do it it would just shake a little at
idle, but only on occasion. It was doing that a little even after I got the
spark plugs changed out and later on it stopped running on a cylinder all
together and started shaking really bad and a code popped up with code
P0304 which is cylinder #4 misfire (far back cylinder on passenger side
engine bank). The COP was going bad. Changed it out and it's like a brand
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!!!!
jistin 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?
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"
notredame2191: It's the ignition coils almost every time
Cody Deadmond: I like that cluster man
Nestor Suarez: I had a shudder on my 2007 F-150 5.4 V8. Based on what I read online I
changed the plugs and coils and she's purring like a kitten again. But I
will say the service was extremely expensive.
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
Andrew Cuccia: Plugs man. Just had this problem. Shook around 40-50mph.
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.
iRideEnduro: "I will Die Trying!"
Trey Davis: Its your foam seal on your air filter holder
Daniel Buchanan: Between 40 and 50 does vehicle shake real bad!
Brute Triton: hey man..i know u already changed plugs but for future reference..check
Rockauto.com if you ever wanna swap out the coils..fyi i am so happy my
2008 has the sp509s..not tryin to rub it in but that old plug design is bad
Ben Gaudreault: mine was plugs but it could be coils
byondstrngth: Spark plugs, do it and the problem will go away
Matthew Bellmyer: I've dropped three grand trying to correct the issue with my 07. Ended up
replacing the coil packs and plugs across the board. It's been about 2
months since the last time in the shop and about 1.5k miles. Seems to be
resolved but the issue tends to come back for most people. But typically
with this model and year don't waste money on the plugs your coil packs are
Romancio Gallegos: Around 40-60 my truck shakes really bad. Could it be a misfire also?
BEBNC1: This problem has plagued me for about 50k miles now... plugs and replaced
coils only temporarily fix the hesitations/misfires (come back after
5-10k). Combine this with the horrible head and spark plug design and the
overall horrible maintenance issues with the engine (VCT cam phasers).
Very, very poor engine design on Ford's part (mechanics consensus). To the
point that I will not own another Ford for a while.
tim fist: Hi , Its your PLUGS ! Ours did exact same thing ! Changed plugs - all OK .
Watch out changeing plugs VERY Difficult ! Tim
mike caissie: when you say rough idle.. is it like a weird shake when stopped in drive?
mine has some sort of a weird shake.. its more of an annoyance
Riley Brown: its the coil my 2002 does it and it idles rough especially when you take
off have to code it when the check engine light is on it will tell you what
coil it is then you have to replace it it worked on mine
Nico Cabrera: I've got this issue with my navigator. Mechanic changed 3 coils so far and
still feel it. Ford quoted me $750 starting to change plugs and more if
they break. Needless to say I can wait
Joe Tumminello: same thing with my 2007 F150. no codes, finally replaced plugs and truck
drove great - for a while - but beware, in the past year, I've replaced the
catalytic converter, and now I am being told that I need a new engine!
$8K! Only 130,000 miles. My take, this year (2007) for Ford is riddled
with design / mechanical flaws. I'm not a big fan of aftermarket warrantee
products, but if you own a 2007 F150, and you can still purchase one, it
might be a good play.
TheTerminator310: 2k? Are you serious? I hope that's not a spark plug change cost. If it is,
I hope they kissed you first. When I had the spark plugs changed on this
truck (which solved my misfire issue), after tax and everything -- $445.
TheTerminator310: I probably couldn't even lend $45, haha. Mine has been really good too.
I'm right at 100,000 right now. So far the spark plugs were the only thing
that it needed. Gets about 21 MPG highway. So far I'm happy with it.
They're good trucks, but just like any vehicle, something can go wrong and
turn into a money pit. I keep up with maintenance very regularly on this
one. Hopefully I'll be good for another 100,000.
jasontman36: YO! Sounds better then my truck! Mine finally just quit on me. So far the
shop wants 2k to fix everything! I dont have even 1k!
Juan Chalico: Would it tug?
jasontman36: I tried to restart the engine the last time it died way too much! I ended
up blowing my battery and starter too! I knew I had a problem about 20k
mikes ago but I was an asshole and thought the problem would fix itself. I
ended up needing a new throttle body too! Tomarrow they are doing a
combustion test to see if the heads and gaskets are still good. I bet they
are not! After I get this truck fixed I am going to the FIAT dealer and
getting a Fiat 500 Abarth! I am sick of huge gas bills! YO!
TheTerminator310: You drop about 35 horses from a dead cylinder. Yeah, you can feel it a lot,
haha. I was lucky that the plugs and 1 coil were the only things that
needed replacing. So far, 15,000 miles later it's still doing good, *knock
TheTerminator310: Yeah, it's just a sensor(s) that has went bad. I think I'll fix mine by
just putting a piece of electrical tape over where the light is, haha.
TheTerminator310: No, it's not that. A simple occasional misfire does not suggest a bad
engine, but more so an injector (or injectors), spark plug, spark plug
wires, coil pack, etc. Just getting to the source is the main thing.
Usually easy. Sometimes, a pain in the ass, haha.
Matthew Pound: I was under the impression that this is just the way 5.4s ran hahah
2003LincolnLS: ummmmmmmm seafoam the truck then see if it still misses
Kallie Lovelace: My brother's truck did this and so did my aunts. It was the spark plugs on
both of them.
Jared Sebesta: My 06 had same problem . Ended up having low oil pressure ended up scoring
my valves ended up getting a new motor. I would get her checked out
TheTerminator310: I've done put alot of carbon cleaners and injector cleaners through the
engine. I guess seafoam will be my next try. Probably just going to try a
full tuneup and replace wires and plugs to see if that'll do it.
Jared Sebesta: Yeah my bad my phone wasn't showing them
TheTerminator310: That sucks hard, man. How many miles on it? And did it go out all together,
or did it just start slipping?
TheTerminator310: I bet it was the hydraulic pump that went out. Does it whine when you put
it in Park? That's usually the first thing to go.
Nathan Weiler: it could be your Cadillac converters i have an 04 and it did the same thing
check them to see if there clogged
