Ford F-150 (2004-2008) :: 2006 Truck Starts To Skip And Shudder Under Acceleration At Around 40 - 45 MPH
I just bought a 2006 F150 with the 5.4 triton motor. Under acceleration at around 40-45, the vehicle starts to skip and shudder.
Based on what I read online and the fact that I pulled a code for a #1 cyl misfire, I assumed that i just need to change the plugs, and I am trying to scheduule that now.
I just read another post about the TC not locking up due to needing the filter and fluid changed and a way to fix that would be to take OD off and see if it still does it.
When I drive with the od off, it does not do it but i am now confused since i got the one code for a misfire.
Ford F-150 (2004-2008) :: Shudder When Turning Right With 10% Acceleration?
I have a shudder that happens when turning right at a grade of about 10% while accelerating, and only on that condition. While making a routine drive somewhere, there's a turn with that one condition. Every time it shudders. It doesn't bother me because it happens so rarely...

I finally upgraded from my 1998 F150 5.4 to a 2008 F150 Lariat supercrew 4x4 5.4 3v with 83k miles. I've had the truck about a week and have already noticed an issue. During light to moderate acceleration, I notice a slight hiccup in the 30-40 mph range. This "hiccup" is best described as a quarter second dead spot in the throttle. At times, I have noticed an additional hiccup between 20-30 mph that does the same thing. Occasionally, I will also feel a slight vibration on take off. It's important to note that if I accelerate at a quicker pace or really get on it, I can't feel the issue. I have also had a tough time replicating the issue when I deactivated overdrive. Not to say it wouldn't do it, but I really couldn't tell if it was doing it. Also, I've noticed that when I really get on it, It takes maybe a second to catch before accelerating. (From what I've read, that's common for 5.4s though, just thought I'd note it)
I have had spark plug and coil pack issues out of my 1998 model, but they felt different than what this truck is doing. Is it possible that this is the same issue but is manifesting itself differently? I briefly spoke with my mechanic and he seems to think it sounds like a torque converter issue. He checked for codes and none were showing or pending in the computer. Transmission shifts good. Fluid is a pinkish orange color, and there are no metal shavings on the oil dipstick. I started to notice the truck would sometimes shift a little hard into 4th. I took the truck by my mechanic and he rode with me. I was able to replicate the original issue. He told me it felt like something in the transmission. He said that my fluid smelled a little burned to him, but it was still a pinkish orange color. He said he would service the transmission and adjust the bands. The truck has 83k miles so I'm not too worried about a major transmission problem. He said he was fairly certain the servicing would correct the issue. I'm also going to have him put a new set of coils and plugs on as well. Am I missing anything?
Ford F-150 (2004-2008) :: Limited Slip Shudder During Acceleration On Turning
I picked up a 2004 F150 a few weeks ago. It has the limited slip 3.73 rear end. During acceleration on turning, I'm feeling quite a bit of chatter out of the rear end. I've read the TSB on it, and I'm wondering how much it'll cost to get the clutchpacks replaced in the rear differential.

I am having a minor problem with my 05 F150 Lariat. Under light acceleration going up a slight grade the truck sometimes shudders (vibrates?). If I let off the gas or accelerate slightly it stops. At first I thought it was a feedback loop with the electronic throttle so I had the dealer reflash the computer but that didn't fix it. I've noticed that it happens right about the time the torque converter locks (looking at the tach) and I'm sure it has something to do with torque converter locking up and then disengaging continuously. Funny thing, it seems to happen frequently on the same hill at the same speed. What was done to fix it?

I have a new to me 2005 F150 with 86,000 miles. When I am driving through town at a low acceleration or a constant speed at between 40 - 50 mph the truck starts to sputter and kick a bit. When I give it some gas the problem goes away. This gets worse when I pull my bass boat, and starts at around 30 mph. When I hook it up to a reader I get a P0316 code. Only code I get.
Also when I am driving through my neighborhood between 20 - 30 mph I get a noise that sounds like there is a plastic bag stuck under the truck. I have checked under the truck to see if the firewall is loose anywhere, but could not find anything. Other than those two issues the truck runs great. What these problems could be?
Ford F-150 (2004-2008) :: 2006 - Truck Downshifted And Falls On Face Under Hard Acceleration
I have an 06 F150 2wd with the 5.4. Today on my way home I had to cross traffic while getting on the highway and had to get on it a bit. When I gave it the gas the truck down shifted then just fell on it's face until I let off the gas a little then it sped up like normal. It normally runs great but I don't get on it much. I just don't see why It runs great until I try to get a move on.

Ford F-150 (2004-2008) :: Engine Seafoamed - Motor Noise Upon Initial Startup After Oil Change
Today I decided to do some maintenance on the truck as it needed an oil change and some other unrelated misc stuff.
1. I seafoamed the engine thoroughly. I bought two cans of this stuff, half of a can went into the fuel, another half can in through the brake booster vacuum hose, and I dumped a full can of into the oil. Took it for a 30 minute drive, let the ol' gal smoke as it usually does on a seafoam, and then changed the oil. No noises, I noticed immediately improvement in acceleration.
2. Upon intial startup after the oil change, I thought the motor was coming apart. It was only for about two seconds, (i was counting to make sure) if it didn't have oil pressure and no noise by 3, I was shutting it off. It hasn't done it since.
Is it possible I just knocked some crap loose in the heads causing the oil drain a lot faster into the pan than I expected? I'll try it again in a few hours after everything has cooled off and oil has drained back into the pan, but I wanna make sure I didn't damage anything. Still drives good, no problems, no noises since.
The last oil change I did, I didn't do a Seafoam, but I figured with winter coming it's a good idea to get her running in top form. I used Pennzoil Platinum 5w20, with a Motorcraft oil filter for those wondering.
Truck has 133K on the clock, and it's had the slight cam phaser tick since I've purchased it, no other problems. I bought it almost a year ago.

View 1 RepliesFord F-150 (2009-2014) :: 2013 - Shudder At Low Speeds Like Driving Over Rumble Strips
I hooked up the boat and went out for a tow. I ended up getting a pretty good vibration and thought maybe it was time for balancing the trailer tires. As it turns out I needed two new tires as they were at the wear bars (cheap crappy bias ply tires) so I ended up buying 4 trailer tire radials and had them balanced.
As it turns out I have what I guess is a shudder at slow speeds and also can feel it at other speeds as well. A way to explain it is that it sort of feels like you are driving over the rumble strips on the side of the road but really small ones.
Ford F-150 (2004-2008) :: 2005 - Rumble At Idle?
my 05 f150 5.4 with 76,000 has a weird rumble at idle, I don't think its a miss and there's no codes and when I put it in park it goes away or if the idle changes just a little you don't feel it. And you feel it through the brake pedal the most its not real bad butb enough to bother me.

I bought my f 350 new from the dealer and have had many of the problems associated with this truck. Now I have a severe shudder while under acceleration when i either let off the gas or increase speed the shudder goes away. My dealer thinks it is injectors but I have little faith. Shudder seems to be rpm consistent and seems to be in the front end. oh yea it idles great and runs great except at that specific range.

View 3 RepliesFord F-150 (2004-2008) :: Idle Rumble Came Back Slightly And CEL Came On
I bought a '05 F-150 with a 5.4 with 112k miles on it a few months ago. It had been sold from an auction, looked really clean, and a good price. Not long afterward it started having issues with running rough at idle. That's when I found this forum and began reading. Tried different things but it only got worse and finally had a shop look at it. Cam phasers were not doing well. Not a cheap fix but more involved engine work than I had ever done so I had them do the work.
It ran fine for a few days and then the idle rumble came back slightly and the check engine light (CEL) came on. I read the code and it came back with a number that indicated air flow was an issue. Internet search said to clean the throttle body. Some threads on this site also said do the Mass Air Flow (MAF) sensor while I was at it. Much has changed since I used to work on cars as a kid. Everything has it own cleaner. I cleaned the MAF sensor with MAF cleaner. Cleaned the throttle body with throttle body cleaner (it was beyond filthy) and a toothbrush. Put it all back together (started late and it was dark by now) and took it for a quick run to see how it had improved. Instead of smooth, it started running even rougher, and within 100 yards went into fail safe mode. Now my mood is getting darker. Park it and go inside to watch the Aggies in their bowl game.
Good game but the truck is still running rough and I am losing confidence in my ability to do simpler things on it. I get up the next day and run codes on it. It had three codes all pertaining to air flow or the throttle position. I am thinking I screwed up the throttle setting somehow when cleaning or maybe only put the MAF sensor in upside down (that seemed unlikely since the screws only seemed to line up in one orientation). So I open the hood to check the MAF sensor just in case and find to my embarrassment that, in the dark, I failed to plug the MAF sensor back in. The problem was a loose screw holding the tools. I plug the sensor cable onto the sensor and take it for a ride. It runs great. Life is good. MPG is climbing higher on the onboard display. My confidence is returning even after humbling mistakes. After everything, I still love this truck.
So, now for the tune-up advice. The truck runs well but still rumbles slightly. Based upon everything, I believe it was well cleaned before it sold but maybe not fully serviced. Spark plugs were possibly never done. I intend to do a tune-up on it but do not know what has already been done so I'll assume almost nothing. The air filter looks brand new. The serpentine belt has nicks so that will be on the list. I am thinking of changing the following:
Spark plugs
Spark plug boots
fuel filter
serpentine belt
PCV valve
Oil was changed when the cam phaser work was done. So the advice really boils down to a question:
Is there anything else I should consider changing or doing or cleaning? I have not worked on cars much in the last 30 years but am beginning to enjoy it again.
Lexus GS 2006-11 :: 2008 GS350 CPO - Transmission Shudder / Shake On Light Acceleration?
About 6 months ago I bought a '08 GS 350 CPO. Love the car but after a month or two of ownership, on light acceleration 3rd and 4th gears will shudder. The whole car will buck and shake, but if I give it more gas it will smooth out. Doesn't seem to be the engine, I suspect more the transmission. Of course I took it in and they "could not reproduce the problem"... Is this just a normal characteristic of the car?
View 14 RepliesTouareg :: Shudder / Rumble Just Before A Stop
Whenever I stop my T-Reg (like at a light, etc.) I feel a rumble and can see the RPMs take a quick dip below where the car normally idles (this happens just before the car has fully stopped). Pretty much I feel the rumble for about second and at the same time can see the RPMS rapidly dip. When the car has made its full stop the RPMs come back up and the car idles normally. Sometimes the dip is more drastic than others, but you can definitely feel a rumble or shudder. It almost feels like the rumble associated with a car getting ready to stall; except it never stalls. What is causing this?
View 5 RepliesFord Super Duty (1999-2016) :: Shudder Like Driving Over A Rumble Strip / Clunk Underneath
My vehicle had a shudder which felt like driving over a rumble strip. It would usually occur after hitting a small bump at around 35 mph and hearing a clunk underneath. The shudder lasted just a few seconds. Checked the whole steering, suspension, chassis, drivetrain, u-joints, rear e-brake shoes etc. Finally found that the RF axle shaft could be moved up and down excessively in the steering knuckle. Removed axle shaft, R&R u-joint, vacuum hub seal and the torrington bearing in the hub. (used to call it a spindle bearing) ...
There was a little bit of wear into the stub shaft where the spindle bearing rides. That removed the play from the axle when it was all re-assembled. I was very happy until about a month later when it started doing it again, but not as bad as it was originally. I think maybe the stub end of the axle shaft needs to be replaced due to the wear in it. I don't want to just throw a somewhat expensive part at it without some info about "superduty shudder".
