Ford F-150 (2004-2008) :: 2007 - Shuttering / Shaking Like Ran Over One Of Traffic Bumps
Feb 9, 2015
I have a 2007 Ford Expedition with approx 135k miles with a 5.4. At approx 45 miles per hours it starts shaking and shuttering. It feels almost like you ran over one of those traffic bumps. I've had quite a few issues I've been working so I recently changed all my plugs with motorcraft platinum and all new COPs.
When I am going approx 45 miles per hour it will shutter for about 1-2 seconds with overdrive on. You can almost time it that it will do it every 4 seconds. With overdrive off, you can feel something dragging down the engine and hear a light grinding noise or a mechanical sound but the shuttering is less. I feel there is something definitely cycling approx every 4 seconds.
When i am doing heavy acceleration I feel that it has adequate power and now that I've replace the plugs/cops I don't feel any significant misses etc under hard acceleration (before I changed the plugs/cops I did feel misses).

I recently bought an 04 lariat crew cab with 56K miles 5.4 and auto trans. Before i bought it i complained about an exhaust noise and acceleration issue at 40mph and 1100 rpm as well as the ac not being very cold. They replaced the exhaust manifold on the passenger side, coil pack on the #3 cylinder, a transmission flush, a flash drive update and recharged the ac. This seemed to take care of the problem but i mostly drove under 30mph and did not notice it. I took it on a few road trips, and country roads and noticed the problem of sputtering and shuttering between 40-60 mph's after decelerating and slowly accelerating. The problem occurs consistently with ac and over-drive on in the above mentioned conditions and mph range. Problem is less noticeable with ac off and have not noticed it at all with over-drive off. It feels like a limited slip kicking in or driving on dry pavement in 4wd. Tranny shifts fine through all gears in a straight pull of acceleration and even full throttle pulls. Problem only occurs after decelerating and slowly accelerating. I don't know of any codes as I don't have a code reader, but I have not had any check engine lights come on nor has the dealer mentioned any codes.

I have had the check engine light on for a while now with the truck shuttering and bucking along with loss of power. Feels like there is something holding back the power. Just a couple days ago I was driving on the freeway and all of a sudden it felt like I was in neutral, tried to accelerate but the engine revved but wouldn't go anywhere, I clicked the overdrive on and it went into gear and I was able to drive home. Now every time I drive it, it goes a block or two in drive then again feels like neutral, put in overdrive and it goes into gear. I just put in new ignition coils.

My problem is I bought an 85 motorhome with the 460. After getting it home I realized the accelerator pump was leaking. The engine ran great and I drove it home over 100 miles. After pulling the carb I replaced the pump and put it back on. Then I had a big leak from the secondary bowl gasket, but the engine still sounded great. When I replaced the bowl gasket then I got a leak from my metal fuel transfer line between the bowls. Engine still sounded and idled great. Pulled the carb again and this time replaced the front bowl gasket the 2 o rings on the fuel line and put it back together. Now I have no fuel leaks but the thing would kind of Idle but it shuttered the motorhome like crazy and then die. It would start right back up and do the same thing.
So I had a leak. Engine ran great. Then I replaced
Both bowl gaskets
Both o rings on fuel rod
Accelerator pump and that' s it
What could my problem be. I have only made one adjustment and it was to the IDLE screw to keep it from dying but it still has the shakes.

I have an 07 f150 v8 5.4 and it idles very rough. When i start it it seems to start really rough and just about everytime im stopped its shaking just enough to annoy me. Do you think its the spark plugs? I took into the dealer about a month ago and they said everything was fine. But its still doing the same thing. Also the A/C tottaly sucks is that they way it is? When I accelerate the cold air gets kinda warm and it doesn't get cold until i get up to speed.

I have a 08 2.0T sedan with 97K that I have been chasing a "shuttering" feeling in the front end when I go over harsh bumps like railroad tracks and frost heaves that we get on roads here in NE.
At this point the front suspension has had a lot of improvements done and problem still exits.
Front suspension work over last 6 months:
- New LCA Bushings (solid rubber style rear and Whiteline front)
- Koni FSD Shocks
- VW DG Sport Springs
- 034 Density upper strut mounts
- Meyle HD Sway Bar Link
- ECS Sub Frame Bolt Kit
After all this there is actually an increase in this shuttering feeling most likely due to a firmer suspension now with new springs.
The car drive fantastic, the feeling that there is something loose up front and the shuttering feeling when hitting harsh bumps is diving me crazy.
In addition, I drove a local VwVortexer's 06 Passat that is riding low on coilovers and it did not have this same shuttering from the front so pretty sure what is going on in my car is not normal.
Completely went through front suspension last night and tripled checked that everything is tight and secure!
Also, have upgraded sub frame bolts with ECS kit and checked all the bolts to make sure they are tight and all is good.
Since after all this work and substantial $$$ investment the problem is still there, should I be looking at motor mounts ?
The engine/tranny is no where near secure sitting in the existing mounts, have noticed two things that have been this way for quite awhile.
If parking brake is not on when tightening or breaking loose lug nuts car has a lot of rock back and forth and you can see engine moving a lot if hood open.
Last night I put a large screw driver between right side mount where piece from engine goes into frame mount and I can move engine side to side with minimal effort about 1 1/2" or more.
One more thing, when coming to a slow stop at the last downshift just before you stop I get a light clunk from left side somewhere and if you slow down from 50 mph or so to 25 to 30 mph and then put gas back on you get a left side clunk too but not always. Does it sound like bad mounts?

Have noticed within the last month or so and also been brought to my attention by another ISF owner that when ever I go over any type of undulation/bump in the road that the lights (lowbeams) visibly can be seen vibrating and shaking on whatever they are shining on...

OK, 05 v8 4.6l
I am having very random overheating for last few weeks. Started randomly one day in stop n go traffic. Thought maybe struck tstat so replaced it. Same thing...replaced water pump, fan clutch, serpentine belt, coolant reservoir cap since then. During all those replacement I flushed system with garden hose. Burped system to best of my knowledge. Still overheats randomly. Seems to happen every day now at hot times (100*). I drive around all day for work so been watching it closely. Temp gun runs 190* on tstat housing at operating temp. When it was rising up in temp I pulled over and temp gun read 200 ish.... it is in fact getting hot. Any freaking clues? Oh and have pressure tested good....combustion test good...

My 2008 F150 rattles (from engine area) when I let off gas while in traffic or in a drive-through. It almost feels as though it's going to stall. Drive thru, parking lot, traffic are all examples. "Stop and go" push the gas to move forward and quickly let off gas. I let off the gas there is a large rattle coming from my engine. Not sure if it's miss-firing or if it's an exhaust leak or a timing chain issue. I'm having trouble trying to figure this out because it does not happen all the time and have been unable to re-create when I go to the mechanic.

I have a 04 4.6 f150 4x4. I have had some off road wear on the truck but put a stop to it here recently. I have replaced ball joints , struts , sway bar linkage , hubs , and now have a clunking sound going over every bump no matter the speed. Everything is tight underneath while stopped, other than the front driveshaft. It seems to have too much play to me? What it could be ???

2004 xlt scew 5.4 Have a noise when rear axles goes over bumps no noise when front end goes over them. Sounds like a piece of wood bounceing in the back when going over rail way tracks. its not a metal on metal sound.
Cant find any thing broken or loose. I know if the spare is loose it will make that sound but its tight. What could be loose.?? Heat shields all seem tight.

I have owned my truck since mile 1 and have not had any issues up to this point. That being said in 2011 there have been 5 occassions where I have been on interstate driving between 55-70 and had to pull over due to my truck shaking. This shaking is very extreme and truly scares me, thus the reason I pull over. I replaced my tires with Michelin 70,000 mile tires and also replace my front brakes just over a year ago.
After not being able to reproduce the shake for my mechanic, they said my upper front ball joint needed replaced and my rear shocks. They hooked the truck up to the computer and did not receive any codes and my check engine light has not come on to this point.
The research I have conducted to this point has pointed to a number of issues and I had my mechanic check all of them and they said nothing was out of the ordinary, these were: e-brake issues, front brakes, calipers, plugs/coils.

My driver door is just loose enough to rattle on bumps and it's quite annoying. I've loosened the striker and tapped it in as far as it'll go with the hammer and it is still not tight enough. I need about 1/4 inch more and that's about how worn my striker is. Obviously I need to buy new a new striker based on the wear, but am I the only one with strikers wearing too much to be adjusted and causing rattles ?

Floored it.it misses fired like no tomorrow and no power, looked down check engine light was flashing. Then all of a sudden everything normal. Now its intermediate and light solid on. So I thought I will just I will hook up the code reader. And NOTHING it didn't turn On. No beep nothing. Tried 2 readers no connection. Trucks a 2005 ford f150 fx4 5.4 217600km on the clock

I have a 2007 an at about 52mph the truck has a slight but irritating bounce (up an down) an after a while sickening. It maybe felt it was coming from the rear. So I had the rear tires balanced an the guy said my right rear tire had a bend to it. Well assuming that the balancing fixed the problem it did not. So I'm going to put on the spare to see if it still bounces what else should I do?

I've done some research on the shaking that is occurring on my truck an it's a possibility that it's the e brake seizing up. I've read where everyone has taken it to the dealer to get it fixed ....

It seems like I am going thru brakes I just replaced my brakes in May and my Rotors in July and when I brake my truck shakes like crazy. Is it the brakes again or am I missing something.

I have a 2006 F-150, V6, automatic transmission, a little over 214,000 miles. When I started it up this morning, no issues, but when I dropped it into reverse, it started shaking pretty bad. Got on the road and put it in drive, and the shaking continued, then the check engine light started flashing. Haven't had any problems up to this point. Checked all the fluids including the transmission fluid a few weeks ago and all was well.

I have a 99 F150 4x4 it recently started shaking badly on the front end at about 40mph but levels out at about 45 to 50 mph or if slowed back down to 35mph. I can't find anything worn or loose except the sway bar bushings are completely gone on both driver and passenger sides. I have read about the "death wobble" but can't find anything else worn out! I can do most all repairs and checks myself.

I have an '05 5.4L 3V and I was way to trusting in how it was running. BTW, I change the oil every 3 to 5 and have only driven highway miles, albeit a lot of them...155k! I bought it with 40k on it but was not aware of the plug change issue until I heard about it off-hand. I let the plug change go cuz it was running so well. Bad move.
Anyways, a few weeks ago it began to lose power and I suspected that the PCM was retarding the timing for some reason. Before I could get to the shop, the thing went nuts on me at 75mph. Started shaking and sputtering and throwing cel codes. I shut it down and after 5 minutes re-started. It seemed fine and actually was running a bit better. Took it in and the code was the 0302. #2 cyl misfire.
They also said the compression was very low on that cylinder and slightly low on 1,3 and 7 as well. I had them change the plugs and the #2 COP even though they said I needed a new engine and then I picked it up. Now the engine barely runs at all. It shakes violently, where to go from here. What should I do now? New engine?
