Ford F-150 (2004-2008) :: Truck Starts To Shutter When Slowing Down
Sep 10, 2014
Read a few references but nothing seems the same as what I have... 2001 Ford F150 Larite 5.4L 4 x 4
When slowing down, at speeds of 3 to 4 miles per hours truck starts to shutter. It is not an engine issue, nor a brake as it will occur with brakes on or not applied. Engine is running smooth, seems more mechanical that fuel or brake related. Shutter is not slight either.
Both CV axles, hubs, rotors and upper and lower A Frames have been replaced. Shutter was happening prior to the replacement, they were replaced as preventive maintenance. Shutter is profound enough to shake the mirrors. What it can be.

When I put truck in 4wd rear end starts locking up. Take out of 4wd its fine. Just put 2 quarts of fluid. They didn't have the 75-140 so I put in 85-140 was that bad. Had rear rebuilt a year ago. Mechanic said he had to put a different gear assembly because ford didn't make the original any more. Ever since this was done rear just never seemed right. Now in 4wd if I go straight it's fine but as soon as I make a turn rear locks up almost coming to a grinding stop.

I took it to the dealer and they blamed the trailer. I told them that I have pulled two different trailers and it did it with both. Then he said that the trailer was not heavy enough to weigh down the springs. So now I not suppose to tow an empty trailer? Also my father in law has pulled the trailer with his Z71 with no shake and the other belongs to a neighbor with a 98 F150 with no shake. The vibration only starts above 45mph. Any clue as to what could be causing this?

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.

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?

This is concerning my little brothers truck. It is a 2008 4.2 liter with around 55,000 miles on it.
He drove it to work today, and called me this afternoon saying that the truck starts then dies a few seconds later, and the battery light illuminates. He and a coworker checked the battery and connections....cleaned off corrosion on terminals, battery reads 12.xx volts without a load on it, it is the original though.
As of right now he is changing the fuel filter which hasn't been done yet. I also know of issues with the fuel pump driver module. I remember checking the one on my 2005 back when I owned it. As I recall it causes a no start condition, but would it cause a start then stop condition like this? He will check this when he is done with the filter.
Anything else that we can check in a parking lot to try and at least get it home?

Had a slight shutter or jerking feeling in their LS, sort of like the rotors are warped, when they slow to a stop from 40+ MPH? I just cannot make the car stop smoothly no matter the amount of brake pressure I apply.
I can 100% eliminated the issue if I shift the car into neutral before I slow down. So it has to be the the transmission not downshifting smoothly. Done it from day one. I even replaced my rotors and brakes so I know that isn't it.

OK so I noticed the last few weeks that I have just a small shutter coming from my rear end every now and then. It feels like it locks up for just a sec and then is fine. It will normally do this earlier in the day and maybe once or twice. Is this telling me its time to add some more friction modifier into the rear diff or do I have another issue. I don't notice it once the truck is warmed up and been driving around some.

I have a 2004 with the 4.6l. The high pressure hose is leaking from rust. From other posts I have read, it looks like I should rent a puller and remove the pulley first, and then I'll have access to where the hose connects to the pump.
Question: The leak occurred while driving home from vacation today. Went we stopped for gas, we noticed a shutter in the steering. I added about a 1/2 quart to the reservoir - there was still some fluid but foamy. I made it home, and I when I checked again the reservoir was empty.
Should I go ahead and replace the pump while I am at it? I wondering it if could have gotten damaged from low fluid. The truck has 190k so it's not like the pump owes me anything. Will it make any of the repair easier to toss out the pump too?

I know how to activate the DAC, read the manual, it says shift to L, put in D, and press the DAC button. Keep it under 15 MPH and when you let go of the brake and gas it will maintain the speed, by engine breaking and breaking.
Here is the problem, followed the directions and the DAC light keeps flashing and the truck speed keeps on climbing no slowing down.
What should I look for? 2004 GX.

After a normal start, about 30 seconds later, the engine starts to shutter with RPM dropping low and surging. If I do not play with gas pedal will ultimately stall. Once it is past its fit, which lasts about a minute, maybe a little more, the engine then runs and performs fine until the next start. This happens with a cold or hot engine. I have replaced the fuel pump and filter. Still have the issue. All battery connections, grounds, etc. are good. No check engine light.
When it starts to shutter it is significant. Reminds me of trying to start a cold piston aircraft engine on a cold day after a couple shots of primer and goosing the throttle.

I was driving down the interstate and sped up to pass a car once I started to slow down the CES light came on and the truck started to shutter really bad. I got it to a scanner and it said misfire Cylinder 6 and he suggested that i change the cap rotor plugs and wires since it has been a long time since it had been done. I did so and and the problem has continues. It idles real rough acts like it is going to die, then under power it smooths out a little but you can still tell it it where. Above 3000 the CES blinks until you slow down and the the scanner still says misfire cylinder 6.

My truck starts sounding off like a foghorn at slow speeds and idle, goes away as soon as you tap the gas pedal. The truck is all stock. 2004 5.4L ....

My truck starts to miss between forty and fifty mph. When you get on the gas pedal it won't do it but when you are slowly increasing speed it will start missing or maybe you can describe it as bucking. Above fifty and below the truck runs fine.

I have a 1994 Ford Ranger Supercab with 180,000 miles, 4.0ltr 6cyl and it is in relatively good condition. When I bought the truck the check engine light was on. The previous owner said that it was something in the gas tank that has gone bad but it was not a big deal and the truck could be driven with no problems.
My mechanics have tried several times to read the error code but their diagnostic tool won't tell them what is wrong.
I have noticed over the past few days that when I am slowing down and riding the clutch (I was making a u-turn this morning) that the truck will shut off. It starts right back up but it keeps happening.
I have been considering replacing the IAC, new spark plugs, rotor and wires and fuel filter but I am not 100% this will fix my problem. I am NOT a mechanic but know plenty of them so it will be a situation where I buy the parts and a buddy puts them in.

So about 3 days ago I made a long 9 hour drive. No problems at all but I did allow my fuel to get a little lower then I normally do. About eighth a tank had 30 miles left on the digital read out. Stopped and filled up at loves where I always get my fuel. And off I went drove it down to 3/4 a tank and made it to my stopping point. Got in to go about 7 miles down the road and come to a stop sign and slowing down the truck died. I thought crap I forgot to turn off the auto start but never done that before. Stopped and stared truck as normal. Made it to my stopping point again. Headed back to the house and doing on average 55mph and truck surges like it wants to die but doesn't.
Rpms drop below 500 and it keeps going I get to same stop sign and slowing down again doing maybe 25ish and truck dies again as I have my foot on the break. Put in nut and started it right up and drive on home. Today went about same distance. Only this time I started it with key and was doing down other things while letting it run it just dies start it back up and take off get to where I was going and it surged or hiccuped so to say. Again started it once I was getting ready to leave and let it run for about 5 min and it died had the heater on as it was chilly out by the lake. Got in and restarted it and it was blowing cold air and had a diesel smell to it. Wife asked me if truck was going to blow up. Backed out of area and put in drive and made it 80' or so and truck died again doing about 10mph
Checked so far
Batteries checked and both are good
No mods done to it
New ICP sensor and pigtail
New water pump
New injectors 20k miles ago
Oil changed 1100 miles ago
New filters upper sad lower

Ok, been trying to track down an odd humming noise on my 08 f150 CC 4x4, 4.6l. kind of sounds like a hub bearing going. starts around 25-30mph and never quites down.
Turning left or right to load each side of the suspension doesn't change tone or intensity of the noise, different pavements doesn't change Tone or intensity. Hubs are tight, CVs are tight, 4x4 works as it should. Cant figure this sound out and it's quite loud.

Truck shifts great from 2 to 4h to 4l and back to 2. However, at random times - any speed - usually when slowing down - I hear/feel something engage and there is usually a ratchet sound. I figured out its the 4x4 - if I switch to 4h then back to 2 quick, it stops. What the heck.

I've got 200k on my Lariat. Engine was replaced 60k ago. It's in outstanding shape and is driven a lot. Suddenly this morning I start as usual and it runs about 5 seconds then stalls out. Every start, same thing. So it seems I am getting fuel pressure to start but it doesn't last.
I did replace the Fuel Pump Module within the past two years, due to corrosion of the FPM housing. At that time the truck would no start at all. Could it have gone bad already? I'm thinking this must be an electronics failure. It was perfect all day yesterday. 2004 Lariat 5.4...

I have a 2007 F150 Lariat with a 5.4 L engine. Bought it 6 weeks ago from the original owner. Has 50,000 miles on it. He had a Ford command start installed when it was new, and received a new key FOB at that time. When I drive the vehicle, sometimes the horn will start blowing and the lights start flashing which to me, indicates the trucks security alarm is activated. The only way to make it stop, is to hit the unlock button on the key FOB. It also does it sometimes when it's not running and I open a door. Previous owner had same problem so he disconnected the horn!!?!
