Ford F-150 (2004-2008) :: Jerking Especially Under Light Acceleration
Aug 2, 2015
I have an 04 f150 with the 5.4 and recently, within the past few months, I've noticed some "jerking" especially when accelerating. At first, I thought it was the transmission, but the jerking does not coincide with the shift patterns. It jerks and stutters around 45-50 mph and 1500 rpms especially under light acceleration. Not sure if one is connected to the other, but also have no real power, I'm barely moving under heavy acceleration. ...What could I be looking at? I am thinking it has several options, I just need to know which one to explore first...cheap, meaning fuel pump/filter?? MAF?? Or Engine Coils?

I have a 2005 F150 XLT with a 5.4 (198,000miles) RWD. A few months back it developed a miss due to bad COP's, typical shuddering around 50-60 MPH.
I pulled off the COPs and while I was in there I pulled my old plugs as well. New Motorcraft SP515 plugs went in with a little nickle anti-seize being careful not to get any near the end of the plug and I put a set of Granatelli COPs on with a little di-electric grease on the inside of the boot. The miss went away and the truck drove like a champ.
I will also note that I replaced the front wheel hub/rotors, front calipers and new pads. I resurfaced the rear rotors, new pads and new E-brake shoes also.
The issue I am having is under light acceleration, or "normal" driving conditions the vehicle has a mild shake which eventually smooths out.
My first assumption was that I did not torque my front wheel hubs correctly or that I messed something up so I took the truck to my local front end/alignment shop for a full inspection and they said everything is great. They also said that they didn't really feel the vibrations that I mentioned. I am used to this truck driving very smooth up until the misfire situation so to me it is quit noticeable. After the front end shop I went to Discount tire cause they mentioned that my rear wheels are bouncing pretty good and that may be what I am noticing. Turns out the tires were out of balance which Discount took care of and rotated my tires while I was there.
The vibration is STILL THERE! No CELs to reference, just an obnoxious vibration. I tried to isolate the issue by accelerating in 1,2, and in D. The issue occurs regardless of the gear I start off in.

My son in law's 2004 F150 had been having a random hesitation and dieing on light acceleration. Now it is every time he drives it.Here is the scenario. After taking off from a stop, with light acceleration, when speed reaches 22 mph in drive, it is like you turn the key off,,,except all the gauges still work,radio air all electrical seems to stay on,BUT the indication lights on the dash and the small red anti theft dash light for the security function comes on. If you try to continue accelerating, the truck will die, but if you let off on the gas and then continue to accelerate all is well.
I tried starting off in 2nd thinking it is a transmission problem same scenario except truck did get up to 29mph before experiencing the dieing issue. Tried starting off with Overdrive disengaged, same problem. The truck is throwing no DTC codes and Ford says unless it throws a code, they can't work on it. Truck runs great at highway speeds . My son in law says that if the truck does die,(by trying to force acceleration) he has to stop, and put the truck in neutral or park, and then it will restart. I have checked all connections at the transmission, rear end and all sensors/controls, but no solution. We are getting desperate and don' t know what else to check. It has the 5.4 engine.

I have recently bought a new truck this month and everything was nice and dandy till i noticed an annoying jerking at 45-50 mph. The check engine light didn't come on till recently when it got really bad and would barely start. I hooked a code reader up to it and it said cylinder 6&8 misfire. So I had the coils replaced on those two cylinders and it seemed to start and idle better.
So I took it on the interstate to see if the jerking was gone as well. and it still jerks at 45-50 just like before. I was going to take it to the dealership to have them figure out what the issue is but that's 100 bones just to figure out what the problem is. My mechanic doesn't want to mess with the spark plugs because he knows they always break.

06 with 5.4 and AT. It shudders in overdrive during light to no acceleration. I was told it was the converter. I was also told by a technician in a trans shop that the Trans-X additive for hypoid oil in a posi-trac was ok to use even though the back of the tube says "Not safe for automatic transmissions". Do this is accurate or if the guy was just blowing smoke?

I have an 05 f150 5.4 and when it shifts into overdrive the whole truck starts jerking, if I turn overdrive off it shifts and runs smooth through all other gears. When it does start jerking if i give it gas and speed up it stops and runs smooth?

I have an 06 F150 4x4 crew cab w/ 108k miles and the 5.4 flex fuel v8. I'm getting a pretty bad jerk while using the cruise control and going down hill, seems almost like it is turning the cruise on and off rapidly while it is rolling. And if so, were you able to fix it and what was the fix? It works perfectly on level road or going uphill, just does this going downhill, very consistently. No lights on the dash, and no other issues.

I'll try to explain what the truck is doing best I can. I'm not sure if it's the engine or tranny. When you lug the truck on a hill or put a load behind it and lug it the truck jerks like the engine is cutting out or the tranny is jerking, I can't tell which. You can drive it all day long on a flat road or small hills and you can't make it do it. It does it worse going up a hill with a load behind it. You can lug the truck on a steep hill let off the accelerator and mash it back down and it will do it almost every time. I've tried overriding the overdrive and it still does it. If you keep the rpms above 2000 up a hill it won't do it. I've had it checked by a transmission shop and they couldn't make the truck do it. Also it doesn't throw any codes or put the check engine light on when this happens. 2007 F150 supercrew 5.4 auto, with 88,000 miles.

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 an 07 ford f 150 5,4 liter. at speeds between 45 and 55 it has like a sputtering and jerking loss of power. I had a computer hooked up to it and it said fuel pump replaced it but it is still doing it, what this might be.

I have a 07 with the 5.4 engine and it has started to jerk or miss sometimes when I'm pulling my trailer. I'm thinking about changing the plugs, but the dealership is telling me they will break off in the head.

2004 F150 FX4 5.4L. I drove from Vancouver to Edmonton and back this week and I started to get some issues. If I'm in overdrive at highway speeds, from about 90km/h to 120km/h give or take, which would be around 1600-2100rpm, and then I try to accelerate, sometimes on flats, rarely on downhills, but always on uphills, the truck will begin to jerk fore and aft. It feels like it's something through the driveline, either the driveshaft or the differential, but I really can't say for certain as I'm stuck in the driver's seat while this is happening.
If the truck downshifts or if I take it out of overdrive, i.e. getting the revs up high, the problem is no more. Other than the issue I'm having, it operates perfectly so this is very odd. I know that overdrive isn't a hill climbing gear, but normally an engine in the wrong gear will simply lug along until it's downshifted. The entire truck jerking shouldn't happen.
On my way to Edmonton, I noticed that this would cause one single, minor jerk. This is my way of describing it, but it was like the driveshaft had spun freely and then promptly re-engaged with the differential gear, causing a clunk. I doubt that's actually what happened, but I'm just trying to explain the sensation. It kind of feels like trailer jerking.
On the way back to Vancouver, it was a lot worse. Like I said, the whole truck would be jerking about once per second but there was one time that I found the sweet spot and it began jerking rapidly, twice per second. I threw it out of overdrive to stop this but the vibration caused the check engine light to flash a few times but it went away and didn't stay on.
What I might be up against? Been doing a little research. Seems as though this is common and it's supposedly the spark plugs, but those only have 50,000km on them.

I have a 2005 F150 S Crew and have been maintaining it regularly. I started having a jerking while accelerating lightly or in between shifting then the overdrive light comes on and then flashes trans fault on dash. I took it to the local tranny shop who fixed the problem however about a year later it started doing it again. What the problem could be before I have to spend another bucks?

I have a 2011 F250 Lariat, 6.2L V8. The past couple months i have noticed truck jerking/lunging during acceleration in the mornings usually between leaving the house and getting on the highway. Over the last 2 weeks the problem has progressed and seems to last longer. I have tried fuel injector cleaner with no success. This morning was the worst so far and after all this time i finally saw the maintenance "wrench" pop up on the on dash.
This was good news to me hoping that a local shop could read the code. However, when i dropped off my daughter and started back up the "wrench" went away. After warming up the problem seems to go away. This morning was so severe i lost speed and felt like the engine was going to stall.
I feel like this is related to the fuel system (injectors/pump/filter) but also haven't changed the spark plugs yet. My truck has 72,000 miles and otherwise is in good shape. How I should move forward?

I have a 2007 2.0T and about two weeks ago the car started jerking while accelerating. It only does it when the engine is cold. Sometimes it does it more than others. Shortly after the engine reaches its normal operating temperature, it stops jerking.
I scanned the computer with my VAG-COM but there are not DTCs. I originally suspected the oxygen sensor but the jerking happens even before the oxygen sensor kicks in. So even when is running a fuel rich mixture prior to getting feedback from the O2 sensor it jerks sometimes.
I have just under 55K miles, so I am not sure about the spark plugs but I find it strange that once the car warms up it stops doing it. The cam follower got replaced about 12K miles ago. The air filter is due for change soon but I don't think that is the problem, last time I looked at it (about 3K miles ago, it didn't look that dirty). I need to check this one again...haven't had time lately.
The only thing that was done recently to the car was the replacement of the transmission valve body under the powertrain warranty. The first few days everything worked okay but then a few days after the repair the jerking started. Could this be a symptom of tranny issues?

I recently bought a 1992 Celica GT with 250k miles on it. It has a rough idle and a couple other things that may or may not be stemming from the same thing that's causing the rough idle
Like I said, it has a rough idle and there is a bit of jerking sometimes during acceleration. The exhaust makes sort of a "put-put-put" or "chirping" sound at lower RPMs and the frequency of the sound corresponds to the engine RPM. I do know of a couple things that could be causing the rough idle and maybe even the jerking, but I'm not sure about the sound from the exhaust.
The cooling fans are hard wired to the ignition so they run constantly, so when it's cold out like it is right now it takes forever for the engine to warm up. Is there a switch somewhere that they are supposed to be wired through? Where would that be? Also, the previous owner did kind of a hack job of putting on a cold air intake and I think I may be missing some sensors, especially because it seems to burn more fuel than it should. What sensors are located on the air intake, or are there even some in the stock airbox itself? And would this possibly be contributing to the rough idle and the jerking?
Also, I do get some vibrations when stopped at idle so I think I may want to replace the motor mounts.

I have a 2007 Chevy Impala with the 3.9L. It has just over 110,000 miles on it. I've owned the car for about 5.5 years. Back in 2012, I took the car to a local transmission shop. Here's the reason: Let's say the car has sat overnight. I start it up (regardless of the season) and go to the stop sign at the end of my street. When I go to accelerate, there will be a very short lapse and the car will seem to jerk into gear then go. This is a very intermittent problem and does not happen every day. The car will do this for a bit when accelerating from a dead stop and then the problem goes away.
The trans shop said the transmission needed to be rebuilt. Guy told me they've seen problems with the Impala transmissions and, if I remember correctly, that the parts used inside aren't the best. Looking for a second opinion, I took the car to a Chevy dealer. The dealer was not able to experience the jerking. I had the trans service done (80,000 miles at the time). The problem persists to this day and has not, noticeably gotten worse. I decided to take the car to another dealer last week. Same thing: the dealer could not create the jerking issue. Again, this issue is very intermittent.
I am not sure what to think or do at this point. I called a couple shops around town and have gotten the following advice/information:
1) Bring it in and we can see if we can recreate it, but can't guarantee it.
2) The transmission needs to be rebuilt (this without even looking at the car).
3) Wait for the problem to get worse so that it CAN be diagnosed properly.
One guy said he didn't trust the dealer mechanics, that they "just drive around the block once." I am not sure what to do?

I have a 2009 Tiguan 2.0T Gas 2WD Tiptronic Auto.
I noticed a while back on a cold morning that at first start the idle would seem off a bit.
I only would notice it for about a couple of minutes and then it would smooth out as I began to drive.
Lately that still happens some but mainly I have some hesitation or slight jerking as I accelerate now.
Mainly it will do it while starting to take off slowly/ when pulling a hill/ and when having to maintain a low speed behind many other cars.
I can counter act it a bit by stepping harder on the gas pedal(when there's room) and getting the RPM to go and stay over 2000 like on the highway.
If it is under 2000 RPM you can notice it pretty well.
I am concerned as I have not had this problem before and it is very well maintained and cared for.
Though it is likely due for a tune up...
What could be the most likely cause? I don't really want to take it to the dealer first as they would want a fee beforehand just to check it out.
It had a check engine light on for just a minute one day but it did not stay on.
If it stayed on then I could get the parts store to check it using the OBDII scanner.

I have a 2010 Jeep Patriot and recently it has started to jerk as I am accelerating. When I get to about 2200-2500 RPM the engine feels like I have completely let off the gas and then put my foot back down on it. Once it showed the Electronic Throttle Control warning light but I have not seen that light again in the past month or so. Originally I thought it might be the spark plugs, but I have changed those and seen no improvement. What could be wrong???

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 noticed the problem today when I was driving to the store. I was going around 60 and went to pass a car. As soon as I hit the gas there is a popping noise coming from the engine compartment and it had no power. It only does it between 50-65 mph.
