Apparently yesterday (no known reason) my sons truck started to develop a miss (so it feels like to me).
2005 f150 5.4 auto 215000km 4x4 stx. No specific cylinder codes. All general codes.
P1000
P1464
P1550
P1703
P1780
None of which I can see causing the miss. No check engine lite, no other codes. Not sure what to look at next. I am starting to disconnect the coil packs one at a time and see if I can pin down the cylinder.

I have a 2004 150 with 165,000 miles I sometimes pull a 5 by 8 trailer. when pulling trailer in overdrive and excelorating the engone will cough several times. I took it to a mechanic and he told me that there was nothing he could do that I needed a new engine. I can pull trailer out of overdrive with no problem. don't undrstand why I need new engine....

I have a 2004 f150 with 135000 miles. Bought it a few months ago. I notice after the truck is up to operating temperature it seems to have a slight miss, you can kind of feel it when sitting in the truck. Cant really hear it. Outside the truck I am hearing a ticking sound. I have changed the spark plugs on the passenger side, because that's where the ticking sound was coming from.
Come to find out the last spark plug in the back was finger loose. Got them changed, on that side. Still have the miss after warmed up along with the ticking. Few weeks fast forward I put all 8 new COP on. Same results. I also have changed the oil and filter both with Motorcraft. Where I could look? I also have a 1 year unlimited mile power-train warranty.

I have a f 150 2006 4.2 liter (basic truck standard) 60.000 km. Yesterday the engine just started chugging and quit I changed the fuel filter. I turned the engine over and the pump did not work when the filter was off so i pushed the emergency shut off button still nothing one question is i pushed the button in it didn't click or anything is that how it works? I have checked all the fuses and grounds what would cause the fuel pump not to work? Or what should I check next?

This morning I drove down to unlock my gate and got out of the truck while it was idling. When I got to the gate the truck just stopped running it did not sputter or anything it was like a light switch and just shut off. I got back in the truck and tried to start it but nothing happened starter did not engage at all or even try to run. I put a new battery in it knowing that is not the problem but it will just not start or even turn over.

My Dad has a 2004 F150 with the 5.4L. Going down the road it just up and quit, when would not even turn over (no starter click or anything), all lights seem to be working and nothing out of the ordinary on the gauges. Mechanic found fuel pump fuse blown then fuel pressure still low, so changed fuel pump. Still not running....

Driving home my radio quit working. I looked at the gauges and they all dropped to the left. The it looked like my lights quit working and then the truck just quit. All of this happened within 5 miles and 10 minutes. I jumped it and quit before I could even get going, it did start momentarily. Could not even get the gear shift into neutral; had to jump it to get that to happen.
It is 2006 F150 4x4, 5.4L engine and about 95,000 miles.

Question, my truck started to have a miss under normal acceleration, when I really get on it, it clears up? I also noticed a bad sulfer smell at idle. Im thinking the cat is possibly plugged? Truck had 172000ish on it, and the cat is original. I did do a big tune up this past fall, new plugs, coil packs, air and fuel filter. Should I put a new cat on it? And a new oxygen sensor?

My 2007 F150's turn signals and hazard lights quit working. I checked the fuse and it was blown. Once I pulled the old fuse out the truck wouldn't start at all. What happened?

My alarm started going off by itself and my truck would not start so we unhooked the horn but the alarm was still trying to go off making a ticking noise when the horn should have been honking. so we also unhooked the alarm. And it started right up. I've been driving it with those things off with no problem. But today it wouldn't start again and its making a ticking noise like the horn is trying to honk.

I had a can of fuel at home that had been siting around a while but I put it in my 02 F350 with the 7.3. hind site being 20/20 I shouldn't have done that. The truck only made it about 2 miles then started chugging and eventually quit. So I pulled the truck home and this is what I have done so far. I assumed that I had bad fuel so I started with a new fuel filter. I did notice that the fuel in the bowl was a milky white color. Not sure what that means. But the new filter did not work as the truck will not start. So after reading some other posts I decided to drop the fuel tank and clean everything.
I did that including cleaning out the 2 screens in the fuel pick up. After re installing the tank I put new clean fuel in the tank and primed the truck. But before starting it I drained the first amount of fuel out of the filter bowl just to make sure I got all of the bad fuel out of the lines. So after doing this I put a new filter in and primed the motor again. I appear to be getting good fuel pressure and the fuel looks very clean now at the bowl. But the truck does not even attempt to start. It turns over just fine but will not start. Some advice I can get before I have it towed to a shop. Also, the truck currently has 305,000 on it and has run great up till now.

At a loss right now. My 2004 F150 4X4 and just recently started sounding like the truck is trying to shift into 4X4 mode while driving it. It stops if it's switched into 4X4. I have taken it to a local mechanic shop I use and they said it was the Actuators and they replaced those. I got it back and the same day the noise came back. Took it back and they have had it for another week and still unable to figure it out. I even took it to another shop that was highly recommended and they say to take it to a Ford dealership. I have read that some say it could be the vacuum operated hubs? Need to figure out what it was and had it fixed?

I have a 2004 Cadillac it started to miss when your idling, a check engine light when on and it was #5 plug not firing so I changed the plugs in front 4 of them and also bought a coil pack and replaced that, but it still misses. What else can I check before thinking its a sticky Valve or internal engine problems.

My truck starts to miss between forty and fifty mph. When you get on the gas pedal it won't do it but when you are slowly increasing speed it will start missing or maybe you can describe it as bucking. Above fifty and below the truck runs fine.

I bought a 04 FX-4 a couple months ago with 102k on it. Brought it back to selling dealer, they replaced #1/#6 coils, its ran great till this past week. Again it has stumbled a couple times this week. It only seems to have the miss at idle (comes and goes) take off from light, within 50 feet its running like a champ again. I cleared the codes (disconnect battery)and now it seems my idle is not steady, it fluctuates. Is the idle a product of the codes?

I have a 2004 F150 5.4L 2WD auto. I had the cam phasers and timing cover done at the end of 2014 and the truck was great. Back in december, I parked the truck and when I started it the next morning, there was a horrible miss. I left it parked a month or two, then tried starting it up last week. Nothing.
So I had it towed to the shop. They found the starter was bad, and the only code it was throwing was P0341... Cam sensor bank 2. I had it towed back to my house, replaced the starter and the grounds and fired it up. It had the worst miss on the planet and died shortly after being started. I replaced both cam sensors, and now it starts right up and runs... but still has a bad miss.
I used my scanner and its still throwing A P0341 code almost instantly. It sounds like a bad miss that slightly gets better when you give it gas... but its not throwing any misfire codes or anything.

We've got a 2006 F150 with a 5.4 in it. One of the new kids was told to change the spark plugs, then when I went to start the truck the next day it was missing bad. Plugged in the Ford IDS, number 7 cylinder is dead. Only codes are for that cylinder misfire, and random miss on startup. So, I double checked the kids work and it was all fine. Tried putting a new plug in, didn't work. Moved the coil to a different cylinder to see if the miss would jump, stayed on number 7.
Used a noid light to verify COP harness was working, and it was. Put a new coil on it anyway since I had one, still missing. Used noid light to verify signal going to injector for the cylinder. Signal was good, replaced the injector for the cylinder. Still misfiring. Ran a compression test and the cylinder has good compression. The threads for the plug are fine, not cross threaded or torn out. The only thing I can think is that the PCM has gone bad in a way that its firing the injector/COP, but doing so at the wrong time some how.
Every other cylinder is running fine, O2 sensors fine. PCM isn't trimming anything back to account for anything, and if it was it would do it to multiple cylinders to keep the engine balanced. Cant think of any more tests, and I don't believe there is anyway that the airflow could be restricted to only 1 cylinder, but I could be wrong. Wanna try and solve this to keep from sending it to the dealer.

I have a 2005 5.4 F-150. First off it came to me on a rollback because the owner tried to replace his plugs after he noticed it missing and of course broke one off. So after I extracted the plug from #8 cylinder and installed a new plug I cranked the truck and it was idling very rough and had a terrible miss around 1200rpm. I pulled the codes and got several misfire codes and ignition coil faults on #5,6 and 7 cylinder. Popped in 3 known good coils in these 3 cylinders with no difference.
On Mode 6 on my diagnostic software you could watch the misfire count steadily increase on #7 and every now and then there would be a single misfire on #5 and 6. It also had several codes for O2 sensors biased, stuck rich on that bank. Well since it had a brand new plug and coil, I popped an injector in #7 and havent had a single misfire on it since and it also started idling alot better and all the O2 codes went away. The problem I am having now is #5, 6 and now 8 will randomly misfire, sometimes build up a steady count on one of them, sometimes just skip around between them.
The truck has brand new plugs in all 8 and new coils on this bank also. The truck has 115,000 on it and does have some cam phaser noise on the bank causing the problem, but its not too terribly bad, I have heard alot worse. My problem is something on that bank only as the passenger side bank is fine. I am wanting to say cam phaser now since this is the side with the noise. I have changed them before but have just experienced the noise, never one running like this because of it. Possibly jumped time a little?

2005 f150 5.4.
I have a slightly rough idle and can feel a miss at 1600 to 2000 RPM. Sometimes running about 65 MPH up a slight grade I can slowly press the gas pedal and the engine will begin to miss much worse, causing the truck to shake pretty bad. When it gets this bad it will slowly flash the CEL and I get a P0306 code (Cyl 6 missfire).
The truck has 148000 Miles on it and the plugs were replaced at approx 120000 by the dealer.
In the last week I have replaced the plug in cylinder 6 (looked ok) and have replaced all the COP's along with the fuel filter and the injector on #6.
I haven't been able to get it flash the CEL light or throw a code since replacing the COPs though and I am at a loss at to what to try next.

I posted a while back about my 04 5.4 having an issue at idle. I did all the normal things like replace coil, spark plug, etc etc. No change to the issue. It still acts as though it's misfiring on a cylinder and I get codes P0306 and P0316. Finally took it to ford and had a diagnostic check ran. Everything on the top end was in working order. The tech even put a known working coil on 6 and nothing changed. I was told that it's either an intake or valve issue on that cylinder. But no definite answer to problem.
Fast forward to yesterday. I got a wild hair at lunch and went out and started truck. Pulled injector plug off of 6. No change to the way it was running. I did the same for 5, 7, 8, 1, and 2. All of which made a big difference in the way it ran. It was obviously misfiring with no fuel to cylinder. This gave me the idea to swap 5 and 6 when I got home to see if the issue followed the injector from 6. I did NOT. I pulled the plug on 5 and got the obvious change in the way it ran. So there is definitely something going on at cylinder 6 that I cannot figure out.
PCM, bad intake, bad valve? I'm not rich so a trip to ford for repair is gonna have to wait. Truck seems to run fine when driving except for slight hesitation during acceleration.
