Ford F-150 (2004-2008) :: 2006 - Jump / Jerk At A Certain Speed Or Have Set The Cruise
Sep 16, 2014
I have a 06 f150 king ranch and I have had this issue before and had tran. rebuilt and motor work done for this and other issues. The jerking stopped for a while but now it is back!
The best way I can describe it is when I'm at a certain speed or have set the cruise, it feels as if it the overdrive has been pushed but it only last for a quick moment then it will continue to do this until I accelerate. Its not a steady jerk.

Since they replaced my transmission at 40,000 miles, I've noticed that occasionally, but not always, there is an unusual quick half second jerk or jump feeling when I first crank the car on a cold start. It doesn't happen all the time, just some times, but it has to be a cold start when I do feel it. What this could be? I'm thinking maybe some bolts weren't put tight enough when they installed the new transmission?

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.

Today I caught a deal on a 06 F-150 with the 5.4l. I noticed a slight vibration that comes and goes at highway speed (65-75), when I got home I jacked the front end up and checked everything out. The right front CV axle is still engaged with the tire when it is out of 4 wheel drive, I can engage the 4wd and everything locks in and works as it should. My understanding is that the axle should spin free and independent of the wheels when in 2wd? How would I go about troubleshooting this?

I just recently bought a 2001 Jetta with the 1.8t (AWD) because it had low mileage and a reasonable price. I've never owned a VW before so I know very little about them in general. This is my second vehicle with a turbo, my first was a Saab 93.
When I purchased the car it had the check engine light on and the codes were Vehicle Speed Sensor and Secondary Air Injection Pump. I was able to get it to stop throwing those codes just by cleaning off the components and reconnecting them. The only predominant problem I've been experiencing is that under hard acceleration in 3rd-5th the car will jump and jerk. Its almost like the car isn't getting enough fuel/air but I'm not entirely sure if that's an accurate diagnosis. I've ruled out transmission issues because there are no problems when driving at a slow-normal acceleration. Any insight on where I should begin to fix this issue would be welcomed because I feel as if my motor mounts will break due the force of the jerking.
My last issue has to do with what happened yesterday. My check engine light came back on randomly when I cranked my car. I had no issues the previous day (besides the aforementioned "jerking) so it seemed odd but what really worried me was when I started driving. Whenever I would release the accelerator the car would slow down suddenly as if I applied the brake. The problem continued throughout the day until I got the codes checked and they read Vehicle Speed Sensor (which I've seen has numerous issues from the factory installation) and the Bank 1 O2 sensor. Today I started my car and the check engine light wasn't on.
My car drove like normal (still the hard acceleration jerking but no dramatic deceleration when I release the accelerator). Now to my question, can an O2 sensor cause a problem like this? Maybe the MAF is bad? Not even sure if this vehicle will throw a code for the MAF ...

So my 1998 Toyota Corrolla jumps and jerks after I switch gears. It only does it sometimes and I have seemed to narrow down that it does it mostly when the air conditioning is on and between 3rd and 4th gear if I don't have the RPMs just right. There is no smell nor any mettalic grinding. I'm thinking it's something to do with the transmission.

I have a 2005 F-150 5.4L 2WD 90K miles. I started getting a misfire and hard jerk when going uphill. No codes for a few days but misfire got a little worse and more jerking at full throttle acceleration or level throttle up a hill got codes p0300 and p0171. I replaced the fuel filter cleaned MAF and changed plugs Motorcraft plugs (none of them broke during replacement). Miss got worse. Missing at idle and no power 3K rmp to get to 40. Only code pulled was p0171. Replaced upstream O2 sensors and COPs. Will barely idle now. Dies when put in gear. Full throttle barely moves forward a few feet just sputters. Checked vacuum lines cannot find anything. Only code I get is P0171. Fuel injectors next? Or shop?

I have a 2004 Ford F150 and the battery keeps dying. We do not use the truck a lot and it sometimes sits outside for 2-4 weeks without being used. If it sits that long, it might be completely dead, but starts up easily with a jump and then works fine for a while. The battery is a 650 amp Motocraft w prorated replacement from 37-100 mo. The local Ford dealer has checked it several times in the past 2 yr and said it is fine, and that if the truck sits for a couple of weeks the battery will die. Is that right? I am not a car moron, nor am I an expert, but I am concerned that they are missing a small draw somewhere in the system. Should I be concerned about a draw or is this just something that happens to batteries as they get older?

I have a 2004 F-150 SCrew Lariat 4X4 with 80K miles. Over the past month or so, every once in awhile there would be a loud metallic "clacking" sound (kind of like sticking a peice of aluminum in a bike's spokes) that would start at higher speeds and would turn into a low pitched whirring gear sound as I slowed down and eventually there would be a thud followed by a sensation of running over a small bump and the noise would be gone. Kind of confusing I know, but that is the best way to describe it. My gut feeling is a wheel bearing or transmission problem....

When I first got this car about 2 months ago, my current speed would be displayed in the MFD when the cruise control was set to on (not activated and in use). For some reason now that no longer happens and it just shows dashes. The only time the speed is displayed now is when I am actually using the cruise control. Is there a way to get that thing back to showing my present speed like it did before?

It started by a minor sputtering while my gf was driving it. It became seriously worse to where while driving at a steady speed it would jerk badly but if I drove and shifted at a high rate of speed if was fine until I released the gas pedal and symptoms returned. I let it set for a week then drove it and it was fine until I shut the engine down and restarted and the symptoms returned. This scenario has happened twice. Autozone tester reported a bad cam sensor. I replaced it and it did not work. I foolishly asked an online mechanic who said it was a crank sensor. I changed that too plus put a new fuel filter on it. Before all this began my truck had been performing perfectly it only has 84k miles but my gf said that she had heard a sound like a pulley was squeaking but I never heard a sound.

I just noticed the other day that my cruise control stopped working.
The cruise light will come on, but when I try to set it...nothing. The speed just drops off.

My F150 4X4 would not start a few days ago, after only having turned it off a few minutes prior. The gauges would sweep wildly and get stuck at various positions. I checked the fuses and they were fine, then unplugged the battery for a bit and it started back up. Occasionally it won't start and i'll have to disconnect the battery again to get it to start.
I'm still having some strange electrical issues though. The radio no longer turns on unless the ignition is turned to AUX. My back up alarm for going in reverse doesn't come on anymore. The gauges take at least 10 seconds to wake up after starting the truck. The dashboard blinker indicators will randomly stop blinking or making any noise. I was thinking it could be the computer, but could it be something else?

How to add factory cruise to my 2005? I am hoping it is as simple as swapping the steering wheel and having dealer turn on cruise in the PCM.

2006 prius. Yesterday gave a jump to a friend with a motorcycle. After I got back in the car, no electricity whatsoever. Jumped my prius using another car, started fine and drove home, no warning lights. Same thing though after turning the car off, no electricity at all, can't start it.
Eventually figured out that I had blown the 120A fuse, so replaced it and the car starts fine now. But... I get the triangle with the exclamation point, and the car with the exclamation point on the mfd. What might be causing this? Battery reads 12.5v with car off. I find it a little strange that I didn't get any warning lights when I jump started it, but do now that it starts from its own 12v battery.

I'm experiencing the tug/jerk/shuddering in my 2012 Escape v6. It happens more around 70mph or 2,000-2,500rpm.
Tug/jerk/lurch/buck happens even more with OD off. Happens around 60mph or 2000rpm with OD off.
Been to the dealer several times even test drove with a mechanic that acknowledges the tug/jerk sensation. No codes or faults. Last visit the dealer showed me a print out of misfire counts and all cylinders were 0 yet on the drive home it was tug/jerk/lurching.

My 04 f150 fx4 has some cruise control issues. The cruise doesn't work at all and the self test doesn't do anything on my truck either. I tested the disengage switch which tested good but replaced it anyway. I've checked all brake lights and replaced the 3rd light which was burned out. I've unplugged the brake switch and reconnected in case of loose connection with no luck. I removed the brake switch and tested as follows.
Top to bottom pins 1-6 for sake of this discussion. Pins 1 and 2 no continuity until brake button is pressed. Pins 3 and 4 are blank so no test performed. Pins 5 and 6 tested the same as 1 and 2 so am I correct in saying the switch is good? My truck will shift through all gears and back without ever applying the brakes. Bad shift interlock inside the shift console? I haven't torn into that yet but it's the only thing left I can think of. Is there any tests to be run on it with a multimeter?

I just bought this truck, a 2004 F150 Lariat, 4x4. It is in great shape, but seems to have a problem with the cruise control... I have been reading different things, but one thing I just discovered is that with the key ON, the brake pedal NOT depressed, I can shift the truck into gear. I know that's not right. So am I needing that switch above the brake pedal and will that fix my cruise control as well?

I bought my 2004 F150 about a year and a half ago and the cruise has never worked. I have checked the fuses (02, 14, 15) and all are good. I tried the diagnostic route with holding the off button but no cruise light ever comes up on the dash. You do have to push the brake to move out of park.

I'm working on a 04 F150 Fx4, cruise control is not working at all, but I can't seem to find the cruise module under the hood. I haven't worked on this year before so I'm not familiar with the layout under the hood. Also, is there a brake pressure sensor on the 04 (new style) like there is on the '03 and below style? there isn't one on my master cylinder, so where would it be? Where to look? Why the cruise wouldn't be working?
