Ford F-150 (2004-2008) :: 2006 FX4 - Hesitate With A Slight Banging Occurs While Coasting Up To 50 - 55 MPH
Feb 8, 2013
I've began noticing about 2 - 3 months ago that while coasting up to 50-55 mph my truck begins to hesitate with a slight banging when it occurs. At first I was worried it may have been transmission, but once I talked to ford mechanics, they reassured me it was not, especially at 85,000 miles. I then noticed that taking it out of overdrive prevents the problem. It doesn't act up unless I am on the highway between 50 and 60 mph. It seems to progressively get a little worse and occasionally I can feel a jolt, as if it's struggling to shift into OD. What the problem could be? 2006 F-150 FX4 ...

I will occasionally get a misfire after a rain storm, lasts about ten minutes then goes away. there is also a slight miss (no CEL) at idle, that occurs all the time. I'm thinking spark plug wires.... the plugs were done last year, but nothing else. to my knowledge the wires and coil packs are all original. i'm at about 114K on a 2004 santa fe 3.5l.
Also, does the computer store misfire codes? I know I got them in the past and i checked it at the time, but didn't write down what cylinder it was. think it'll still be in memory?
Think it's ok to change just the wires and not the coil packs? kind of on a budget...

My F150 has 100,000 miles on it and hesitates and bucks on acceleration. Auto zone pulled a code which I can't remember what it was but did say it was the throttle body actuator was stuck open. I pulled the throttle body and cleaned it with throttle body cleaner put it back on. No change.

I have a 2004 F150 with 195,000mi. For the last several moths the truck has had a rattle on startup, some days it is barely noticable and only on cold starts, other days it is loud and occurs on every startup. The truck was most recently serviced at the Ford dealer and is filled with Motorcraft 5w-20 syn blend and Motorcraft filter Every change before was either Motorcraft syn blend or Penzoil Platinum (I have always used Motorcraft filters on it) and the noise continued after oil changes so I don't think the drain back valve is the issue. I replaced the cam phasers, timing chains, chain tensioners, and guides about 15,000 miles (2 years) ago and the vct solenoids shortly after that. Here is an audio clip of the noise (I know the truck also has an exhaust manifold leak, I plan on replacing the manifold while im working on it
Is this noise the lash adjusters or have the cam phasers failed again (they were dorman parts)? If it is the lash adjusters, can they be replaced without removing the cams? will failed adjusters be obviously damaged? Should I also replace the cam followers? do i need to replace all 24 at once or can i safely replace only damaged ones or maybe just 1 bank (noise seems to only be coming from the pass side)?

This is very weird. A strange noise occurs intermittently. It sort of sounds like a pulley slipping on a steel shaft briefly followed by a brief rattling noise and may or may not blow out fuse number 14 (A/C Pressure switch, backup lamp and daytime running lights, redundant speed control heated pcv, ABS, Reverse park aid, EC Mirror), then the brake light and the ABS light is displayed and the cruise control quits working. It does not ALWAYS blow out the fuse as I discovered yesterday.
The first time it happened (about three months ago) I was doing 75 when it happened and was unable to figure out what it was. Yesterday it happened and I new it was fuse number 14. I replaced the fuse and it happened again within 3 minutes. It may be when I turn the wheel to the left. The first time it happened I was changing lanes, yesterday when it happened I was on a ramp turning to the left. In the driveway it happened as a backed up and turned the wheel to the left. I cannot identify where the noise comes from. After the noise and the blown fuse the truck runs just fine and I can continue to drive.

A very odd hum from the rear (2005 f150 4.2) that occurs at all speeds. Low speed it occurs regardless of load on the drive line. At higher speeds it only happens when i have considerable load on the drive line. All bearings in the diff were replaced less than a year ago when the main pinion bearing went and the diff gears were in pretty dam good condition. Wheel bearings are not getting warm to indicate a wheel bearing. And when i let off the throttle it hums for a few seconds and dissipates as the tension on the drive line goes away. I even looked at the carrier bearing assy and it seems to be in good working order. I live pretty dam far from any type of service so i was just curious before i start trying to trouble shoot this any further.

I have a F150 which has developed a miss or hesitation when driving. I took it into my mechanic and he told me this:
This year truck is famous for needing a tune up but the problem is that ford redesigned the spark plugs for these years of trucks. The problem is hat carbon builds up and when u go to remove them the plugs break and sometimes you have to take the heads off to get them out, he said that this would cost around I 2500 is one breaks!
So my question then becomes is this the norm for my V8 2005 Ford F150?
My truck has 85,556 miles on it.

I just bought a used '05 F-150 and recently I noticed more a shaking I guess you'd call it. When I start from 0 to 80 nothing seems wrong, but when I slow down to coasting like 40 - 45mph and accelerate to 50 - 55 mph it shakes or acts like its having a hard time shifting or its skipping. And it doesn't happen till after I go past 40-55mph range and I've tried it in overdrive and out of it.

My F-150 has developed a rattle and vibration at idle that only occurs with the truck in gear and stopped (with the brake depressed.) The noise appears to be coming from the front of the truck, perhaps from the driver's side (though it's difficult to tell while sitting in the cab).
Before I go crawling around underneath with my son holding the brake while the truck is in drive--I would sure like to know where it might be best to point the flashlight.

I have a 2002 Ford F150. 273,000 miles on it. When I am going about 50 mph and I start down a hill and let off the gas a bit and then when at the base of the hill I push on the gas to accelerate then sometimes it does a weird hesitation or slight "lurch" but it is NOT in the engine. The engine continues to run smoothly during this lurch. It only happens between 45 and 55 mph. It only seems to happen when I am trying to accelerate out of a coast. I had the dealer check underneath thinking it might be a u-joingt? They said everything underneath seems to be in good shape. Someone told me to consider Ring and Pinion Slop problem in the rear differential? When I read about that it seems that it normally makes a noise. There is no noise with my truck's problem.

My 04' FX4 rear door locks hesitate to open with the key fob or the door switch. I can get them to open sometimes but not every time. Why this is happening?

So today I got to 800+ miles and when I'm coasting in gear... When I get it to the point (by the gas pedal) where the transmission is not loaded so you can slide out of gear...(you guys that understand power shifting know what I am talking about...) I hear a whirling noise.... Whoo-Whoo-Whoo- etc...I hear it sounds near the clutch (guesstimating since its near the front/dashboard)
I would have to drive it another 500 or so miles to get home. No mods, started trip with about 300 miles... Did not use cruise control.. Varied speed around 60-90 mph to keep the rpms moving since there isn't a lot of mileage here... Idk what else to say... This is really bugging me... Never launched the car... And I did search, only results I got was from other parts of the forums saying wheel bearing...

08' 4x4. I changed the front brake hoses because the truck felt like it was dragging a bit, when i would hit the gas from a stop, that seemed to work, I also changed the front rotors because when braking I was getting a pulsing feeling in the brake pedal. that fixed that.
Now I feel like there is still a bit of a slight drag when I'm at a stop and let off the brake. when im on level ground the truck creeps forward from a stop when letting off the brake, on the slightest incline the truck wont go forward at all.
Do the truck want to move forward on a tiny incline or no?

It just started doing it the only way I can seem to figure out how to explain it is at about 50 to 60 under slight acceleration or uphill it bucks or jerks like you have a trailer jerking. No check engine light this thing is driving me nuts... 2004 f150 5.4 ...

So, after putting new tires on my truck about 2 years, I noticed a slight shake when I drove at about 90kph. I let it go for quite some time thinking it was just a balance issue.
Well this weekend I spent 7 hours washing, waxing, and polishing my truck. It was worth. The rims reflect the moonlight now. It's amazing. During this washing, I scrubbed in behind the spokes of the rims. I found a big chunk of mud. Well surprise surprise, my shake at 90kph went away... or so I thought.
I no longer have the shake when driving at 90 or accelerating through 90kph like I used to. Now I have the shake when I let off the gas at 100 and drop to 80kph. It shakes at 95 through 90, and then goes away.
What is causing this? The parking brake is never used, and is showing no signs of engaging while driving. Is this a driveshaft issue?

I've been noticing over the past couple years that sometimes when I accelerate, there's a slight delay between the time I press my foot down on the pedal and when acceleration actually happens. From reading other threads it would seem that the most common fix is to re-flash the ECU. I bought a DiabloSport Predator tuner along with a CAI a while back to improve performance/gas mileage and I was wondering if there's a way I can use the tuner to re-flash.
If not, do most ford repair shops already carry these? I don't want to buy a flash programmer. Also, if the shop does carry this type of an item, what is the average cost to get it re-flashed?
I own an '04 F150 XLT 5.4l.

At 89,000 miles I replaced my plugs with autzone autolites and also replaced my fuel filter. Shortly there after the truck started to shutter and shake while miss firing giving a 0307 code. After checking that plug and replacing it, moving the COPs across the engine from each other the miss firing continued under the 0307 code. The miss firing mostly occurred when I was around 50 MPH, under slight strain with a little acceleration. If I powered through it most of the time it would clear out. Occasionally it was bad enough to where I had to pull over.
I trouble shot this for about a month before it got more consistent and worse. I took it to the shop where they tested the compression on the cylinder and also tested each coil. All check out OK. They recommended I replace all plugs with motorcrafts and the boots on the coils. In the process of doing that I discovered a loose plug in the #2 cylinder. I pulled it out and found that it was scorched and the metal was slightly tweaked at the tip. Not sure how it got loose or how it got burned, but figured that I found the problem. All plugs and boots replaced!
Two days later more miss firing. This time with a 0305 code. Occurs again on a grade at around 50 MPH with slight acceleration. I pulled that plug and the plug in the cylinder where the loose plug was found. Nothing seemed to be wrong. The plugs seemed a little brown where I put anti seize on but that I figured was normal. I then moved coils again. The miss fire continued and the code did not move. There is still a rough idle and occasional humming coming from the engine.
Is the loose burnt plug a separate issue or is there something causing all the miss fires that backed my plug out. I'm lost on my next step to take. Im getting married in two weeks so needless to say spending more and more money on this issue let alone time is making things so stressful. Besides the fact that I think my engine going to blow up on me every time it miss fires bad.

It feels like I am having a front bearing issue, when turning the steering wheel to the right I feel a slight vibration in the steering, need to know which one is going out,??? I have already replaced the passenger side twice It just seems to not tighten completely as I can still move the tire slightly while up on a jack...

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 04 f150 2WD I've been noticing a slight vibration on initial takeoff, it only lasts for a couple of seconds then it goes away. I have the "non serviceable drive shaft" the u joints are staked into the yoke. there is some up and down play where the drive shaft goes into the transmission extension housing. Does that play is normal or what may be causing the vibration?

Getting code P0022, which is over retarded cam position, drivers side bank. My 2004 F150 has the 5.8 triton. I have replaced all cam phasers and tensioner a as well as the timing chains. I have also replaced both VCT solenoids. Before I was getting codes for both banks, now just the code mentioned above with a slight ticking as well. My question is this... What am I not seeing? What could be causing this?? Would it be beneficial t get the lockout kit for the phasers to always keep them open?? Seems to stall a little at very low RPM like when you are off-road.
