Ford F-150 (2004-2008) :: Truck Shutting Off When Hitting Brakes Quickly
Oct 18, 2014
I got a 2007 f150 5.4 triton motor 94000 miles all stock just gots mod k&n filter top end rebuilt due to cam phasers and timing guides for the past year when i make a real sudden stop or sometimes quick turn the truck will bog a bit the i give it gas and will drop to 100 rpms and if i keep my foot on the gas the truck will die if i keep my foot off the gas it will keep rolling then die after attempting to accelerate fuel pump driver module is in good shape with spacers the old code i get when this happens is p0191 for fuel rail pressure sensor although i just replaced that what could it be?

My 02 F250 has me baffled. For a while the truck would pull to the right when hitting the brakes and occasionally the brake would get hot. To try and remedy this I put a new caliper and hose on the right front corner a new hose on the left front side. The truck still pulled right and the pedal got spongy even after bleeding the brakes 3 times. I got to checking the rest of the brakes and found a seized slide pin on the left rear. Got that fixed and still pulling right with a soft pedal. I've checked all of the sliders and none are seized. I am lost and I cant stand the soft pedal!

Its a 2007 f150 v6. has 55,000 miles. just got her new tires for Christmas. the truck has doing this for awhile. when you use the brakes the pedal pulsates and the truck jerks back and forth. Feels like bent rotor or something. I've been doing it about a year keeps getting worse. Last year I had the rotors turned and put new pads on got a little better. But not for long continued to get worse again. So I just bought new rotors and pads and still sucks. I thought it could be a bent rim so I just rotated the tires and still no better. Where should i go from here? calipers? something in the front end loose?

Having an intermittent problem when starting the car.
The car quickly shutting off right after starting while still in Park.
It does not do it all the time, but about every 3rd of 4th start attempt it will do this. If I step on the accelerator, I can avoid the car from shutting off.
The car has 62k miles and spark plugs were replaced at 50k.

My f-150 has an intermittent rough idle and consistently runs rough when you accelerate quickly. Vehicle is not throwing any codes?

06' 5.4 screw 100K... At 55mph my truck just stopped running, I pulled over to the side of the road and after two trys the truck restarted but ran rough. Auto Zone pulled a code that said replace the throttle position sensor, I did and the same thing happened again two weeks later just as before.

My 06 FX4 has 106k it started acting up shifting last week and its driving me crazy not knowing what part to change. Sometimes when I take off slowly from a dead stop it shifts really quickly into o/d by the time I am at 15-20mph. Doesn't matter far as hot/cold but if i accelerate quickly it doesn't seem to do it. I have read it could be the Shift solenoid or TPS.

So I was driving home today, I had some issues a couple of weeks ago with it stalling in the rain, it was raining today. As I was driving, the truck dies and won't restart. It wasn't like it stalled, it was almost like someone shut it off. Then it wouldn't restart, and there is a clicking sound under the dash. I tried the battery pull and nothing. Ended up having it towed home.

I drive a 2006 F-150. I'm new to the forum and already found some good info on the annoying tick coming from my 5.4.
I have recently purchased a ski boat and lately when towing my boat and coming to a stop I feel as light movement coming from the rear of the truck that feels like something slides forward slightly. When I accelerate "it" slides back and if I accelerate quickly, "it" makes a loud clank noise.
I have ruled out hitch, receiver, ball, anything from the boat/trailer etc... It is coming from the transfer case/ spare tire area under the truck and it only appears to do it (or to where it is noticeable) while towing the boat.

I got a 04 f150 5.4 and ive ran into trouble and im not sure whats the problem. So im up in the snow right now and every time i start to go threw some thick snow my tires start to spin out and my truck shuts off on me. It only does that when i really give it some gas and my tires are spinning. Could it be the throttle body?

I've got an 04' F150 and the ONLY problem I have with it is a ridiculously sluggish throttle. I bought the Superchips Tuner in hopes of eliminating this, but the delay in the throttle is still there (power is much better however). When I talk delay, I am talking hitting the gas and probably a realistic .5-1 sec delay. It is quite annoying to say the least.
My question...is there something that I can do myself to improve the throttle response? I drove an older 150..probably an 02 or 03 and it felt sooooo much more powerful just do to the throttle. I am even willing to ditch the Superchips if the Ford re-tune would do a better job.

Relatively new Prius owner. I have a 2007 Touring model. I have two concerns I'm hoping some veterans can address for me.
1. I noticed last night that my left HID headlight turns off randomly (I saw it in the reflection of the car in front of me). I turned off the lights and turned them back on, and the headlight was working again for about 5 minutes before turning off again. This consistently happens so I'm pretty much driving with only one headlight on. The right headlight isn't having this problem, luckily.
Looks like Toyota had a settlement over the issue. I would post a link but since I'm a new users it's not allowing it.

When I have the A/C running in my truck it idles at like 900 RPM's if not 950 RPM's. It also doesn't appear to sweat like normal vehicles do. Most every other vehicle I've owned sweat when running the A/C it does but just not a lot. I hear it hiss like the drip is hitting something hot when I shut the door on the truck.

I have a 08 prius and every now and then when I shut off the car I hear the tiniest little beep and I can't figure out what it is. It isn't my FOB as I've already had that beep and fixed it over the summer. It has been going off and on for the last 2-3 months, I can't make it happen on purpose so the dealership thinks I'm losing my mind and no its not my cell phone beeping either. It is definitely the prius beeping ...

My 6.0 powerstroke keeps shutting off when I hit a bump. It's like everything died and reset and I loose all memory to stereo and everything. When I got to work and popped the hood I tapped on the battery cover by the pcm and it shut off again.

Last week the engine in my truck was shutting off while driving. Happened to me 3 times over the course of two days. The first couple of times, the engine was dead for 3-5 seconds and then the engine would come alive and drive normally again. The third time was about a 10 second event...same result, engine refired on it's own and drove normally. I was in motion all three times so the engine restarts all occurred before I was able to bring the truck to a complete stop.
No check engine light...(I didn't pull any codes because I didn't have my laptop with me). So, I decided to try a new CPS. I had one in my glove box since 2003 so in it went. It replaced a black CPS that I purchased from Riffraff about 100k miles ago. The new CPS seems to have done the trick. I've driven about 500 miles since the swap and the symptom has not returned. I wonder how long this one will last. It's a Ford replacement part so maybe I'll get another 100k miles...

Got a POP noise when I hit the brakes. I have to apply some pressure for it to make the sound. Does it once when going forward. Doesn't do it again until I drive a few minutes, then it does it again.
If I go back and forth between reverse and drive, it does it every time as I hit the brakes, but only once until reversing direction again.
Takes some moderate pedal pressure to make the noise. If I turn the steering wheel to either side, it doesn't make the noise.
I've gone over the brakes, nothing there is wrong, and besides it wouldn't go away when I turn the wheel. Nothing is loose in terms of tie-rod ends, wheel bearings, nothing.
It's not bad enough yet to be able to see movement in the ball joints when the wheels are off the ground. Is this the ball joints?

So when i shut my truck off the heater will occasional keep blowing. it also has a string of LED type lights inside the dash by the speedometer, those also stay on sometimes. It's happened before and we thought we had it fixed. We had a whole new fuse box put in and some kind of module. What could be the problem? I am thinking maybe some kind of wiring?

1999 f150 5.4 it's been over 3 months since It happened I hit a pretty big mud hole and right after it starts bogging and running rough and won't drive I made it home and second and I've been driving it around town in second gear since. I've been trying different things since it happened, It runs rough in drive, reverse, neutral, and first (towing gear) but revs up just fine in second (towing gear).
So far I've
- Checked all fuses
- Changed plugs checks coil packs
- Dropped pan changed tranny fluid and filter
I broke a heater core line so I replaced the intake manifold and got a good look at everything and cleaned it out
- Cleaned throttle body
- Checked all connections
- Checked all vacuum hoses
- Replaced maf sensor
- Pulled the codes but I don't have them handy.

I've done the testing of hitting the brakes when the TC is locked and when it's off the shudder disappears. My question is I recently had a trans flush and both internal and external filters replaced. There was a hint of noise before then but it seems it's getting progressively worse. Could it be that they used the incorrect trans fluid? Reading through it seems as if I should follow the steps of dropping the pan and looking for signs and symptoms and then replace with the correct mercon fluid (if that's not already what's there). Then maybe some additives like shudder fix? I just want to make sure I take the correct steps to solve the problem as to not break the bank getting a new TC put in and missed something cheap and easy. Also reading it could be motor related maybe a misfire so just looking for pinpoint the problem.

I have a 03 F250 5.4 4x4 auto, last year I had a problem with the truck shutting off randomly. So after doing all the dumb stuff and research I ended up concluding that the FP relay was acting up and my understanding is that, it is located in the fuse block. So not wanting to replace it I wired up my own relay next to the safety switch in the passenger side kick panel and it has been fine ever since. I did put a new pump in it (Cali emissions) Now to present day-
Over the past month my truck would have a slight hesitation problem when accelerating on the highway/up grade. The issue was it would go away for a while when you would shut the truck off and be good for a while. Well then it started happening all the time.
I knew I was do for a tune up (215,000) so I did all the plugs, COP's, fuel filter and a PM. It got a lot better but was still there at the top end. So after doing a lot of research I found a lot of people having the same issues, so for testing purposes I cut the CAT out and installed a section of flex pipe. (Iwill be installing the cat back in)
So last night I take it out and its even worse...I went don to my buddy's place and hooked up a Versus and got no codes at all, no misfires on the counter..absolutely nothing. So I did what I should have done in the beginning and duct taped a fuel pressure gauge to the windshield and took off.
At idle I have 30 or so PSI, and when it was fine it would stay around that, when it started acting up it would drop to 5-2psi under load and go back to 30 or so PSI at idle. The other thing is now I only have 1/4 tank of gas.
What I am concluding is that the pump is getting hot and weak, because when I had a full fuel tank it was better and now I have less fuel to cool the pump and it is happening faster. Should I just throw another new pump in it? Or go after a voltage problem to the pump?
