Ford F-150 (2004-2008) :: Hesitates And Dies On Light Acceleration And Shifting
Apr 26, 2012
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 a 2004 f350 6.0 it has 73000 miles on it. I've had the truck for about a month and its developed a slight stumble, hesitation. It does it during idle and acceleration, if I give it more throttle it smooths out. The cel is not on and there are no stored codes.It did this a few days after i bought it,i noticed the map sensor was broke in half so i replaced that and it smoothed out.But it came back. Exhaust is clean no white or black smoke at all.

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?

Our 2004 LeSabre has the following symptoms - there's a clicking that occurs whenever the car is in motion, the car occasionally hesitates/bucks when shifting between gears (but not always), the radio sometimes does not go off when the keys are taken out of the ignition, we're losing about a quart of oil about every 2500 miles but there is no sign of a leak on the ground, we also seem to have reduced mileage (using more gas).
In this corner, Mechanic 1 (high price) - replace front lower control arms, sway bar, and bushing, front end alignment, throttle body gasket and EGR tube, oil pan gasket replacement, ignition switch replacement, brake fluid and coolant flush. $1900
In the other corner, Mechanic 2 (low price) thinks it's just the spark plugs and wires that need to be replaced, the wires, replace air and fuel filter, and PCV valve - $450
We had the oil changed about 2500 miles ago, replaced the air filter then. The oil change place suggested a coolant and brake fluid flush. I've used mechanic 1 in the past and they have replaced my head gaskets a couple of times and I suspect they are ripping me off.

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.

OK, so my 2000 FWD 6.8L Ex has 128k actual miles on the odometer w/ a stock 6.8L from a wrecked later model truck with ~115k actual miles on this 2nd engine from what I was told by the PO/2nd owner (I have no reason to doubt him and I verified the history with the original owner). So I'm guessing that the 4R100 is original without having ever been rebuilt.
I've had zero issues with the drivetrain up to this point, this truck has always run like a top and been very reliable. This afternoon in drive time traffic the overdrive light started flashing and at the same time I noticed that the transmission was shifting really hard (snapping into the next gear) and not in a good way. I was in stop and go traffic when it was shifting weird like this. At one point I make it up to 55+ and I noticed that the O/D light had quit flashing and now it was shifting like it normally does. Then back into stop and go driving the O/D light starts flashing again accompanied by the weird hard shifts.
Next thing I'm sitting there with my foot on the brake fully stopped waiting for traffic to start moving through the traffic signal when out of nowhere and no indication of anything being amiss the engine quits and I get dash lights including CHECK ENGINE and THEFT. I cycle the key off and then try to restart it. It took nearly 10 seconds of cranking to get it to start up however once started everything is back to normal and I have NO trouble lights illuminated including no O/D light and it's back to shifting normally. I continue on in stop and go and highway speed driving for the next 15 minutes like nothing ever happened, transmission is shifting like it always has. The truck has been turned off once and restarted since that incident, yet no other indications of any issue. What's going on?? What to check into?

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 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 got my truck to throw some codes. As many of you know I have been having an issue where when I stomp my truck to the floor it sputters and hesitates. Some days its worse then others. It only happens under a load, and it generally doesn't last to long, however today it did it a whole bunch and lasted for a good bit any time I got on it hard. My engine light begin to flash, and there was a smell of exhaust. I went to Autozone quickly as possible. The guy read the code, and this time no lean codes, just a "P0430" which the code reader said was O2 Sensor Bank 2. It also had a pending code, which was "multiple cylinder misfire detected". So my question is can an O2 sensor cause this? Could my CAT on that side be bad?
If that is all it is, is a bad cat or O2 sensor then I will be very happy... Like I said I can sit in my driveway in park all day long, and rev outta my truck. It will never misfire or hesitate at all. Soon is I put it in gear and am going down the road and punch it sometimes it pop and sputter.
Another cool thing is some how their code reader was able to read my ABS light, and I found out that this whole time I have had a bad ABS Speed Sensor in the rear end. That is a plus as well.

My sister in law just got into an accident today because her 2006 Explorer hesitates and dies sometimes off the line. Check engine light will come on, and won't go apparently. If she shuts it off and restarts, it will usually work for a little while again. Today, it happened when she took off on a green light, it stalled out and the guy behind her rear ended her. She isn't real happy with her Ford.

I have a 2005 F150 5.4 and I recently got a p0175 code. I've replaced the M.A.F. sensor, fuel injectors, fuel filter, new plugs, coils and checked the vac lines but I'm still getting a p0175 code. Ive reset my P.C.M. and the code stopped for 2 weeks but returned later. The truck runs fine when I erase the code but when it returns it hesitates on take off and has a slight shake like a misfire and it makes a bubbly popping sound from the exhaust. Im at a loss of what to do next! Could this be a code stuck in the P.C.M.? My mechanic thinks it may be the cam phasers!

About 4-5 weeks ago my 2002 F-250 7.3 just died with no warning after coming off the highway and since then it hesitates/dies when hitting a bump or while applying pedal with the A/C on. The code that keeps popping up is the P0344 "CPS" and the code for back pressure sensor... I have replaced the CPS twice "making sure the 1st one was not bad", the back pressure sensor and the tube the goes the manifold, and fuel filter and still having problems... I didn't know if there could be a fuel pump issue or something else?

Having a slight issue with my ranger. So I bought this truck out of a junkyard about a month ago, its a 94 4x4 with a 4.0 and a five speed. When I bought the truck the motor was blown so a few weeks ago i replaced it with a 4.0 from an aerostar van I had laying around. Right after I changed it the truck was running good with no issues, until a few days ago going to work the truck started hesitating going up a hill. Now the truck does it all the time, sitting at idle the truck runs smooth as silk, at half throttle it does it the worst but when you mash the peddle to the floor it clears up and runs good.
So far I've replaced the plugs, wires, coil pack, mass air sensor, throttle position sensor, and the fuel pressure regulator to try and fix it but nothing has worked. I've checked the fuel pressure it has 30 at idle and 40 with the vacuum hose pulled off of the regulator, I even taped the gauge to the windshield and went for a ride and there was no drop in pressure when it started acting up. a few other things i have done were plugged all the vacuum ports to rule out a leak, reset the computer and checked for codes. the only code that came up was 522. So I think my next step is going to be buy new oxygen sensors ? But my question is wouldn't the check engine light come on if it was an oxygen sensor ?

I have a 2011 super duty with the 6.2 flex. When shifting into reverse, it hesitates, then slams into reverse. Same on the lower gears when driving. This doesn't occur all the time, but the majority. Been talking to a couple other super duty owners (diesel owners) who have been having the same prob, but not as severe. We all have noticed the prob after having charcoal filter replaced. Is this a tranny issue or computer issue?

I have a 2004 F150 5.4 Triton. When coming to a stop the truck starts a rough idle then dies like it ran out of fuel. The tank is full. It is an intermittent problem but is getting slightly worse. It mostly happens after reaching operating temperature. Also there is the dreaded ticking sound once the problem start. Brought it to the dealership and after they had it for four days they said it stalled once and recommended replacing the motor! They could not answer the question as to why to replace the motor. No codes or warning lights are coming on when it dies.

I am getting 14MPG out of my 2007 with a 4.2L 5 speed manual single cab. That seems pretty low to me considering the HWY MPG is rated at 19mpg.
My son and I have also noticed when taking off from a stop it is very easy to kill the engine, it seems to happen more so in Reverse but does it a lot going forward. I have driven many stick shifts and this one is by far the worst as far as it dying on take off, really I have never seen one this bad.
I have also noticed some spark knocking at HWY speeds and it also feels like it has a miss a idle but when you push the gas it runs fine.
Installed Motorcraft Platinum plugs a few months back and checked all the gaps. Also new orielly brand plug wires at the same time.

My 02 F150 4.6 has 84K miles on it, and started stumbling/hesitating during accellartion about three weeks ago. Before this problem started (about 2,000 miles ago), I installed a new fuel filter and air filter. Since I noticed the problem, I installed new plugs. The problem didn't go away, so today I checked the fuel pressure. At idle the pressure is 32psi with the vacuum line left on the fuel pressure regulator (30-45 is normal as per Chilton's), and 42 with the vacuum line off (40-50 is normal as per Chilton's). I also had someone else rev the engine so I could observe, and found that the fuel pressure went as low as 28 when the engine speed was quickly increased. The standing fuel line pressure is 30 (30 is normal as per Chilton's) Does this sound like a fuel pump problem, or is there something else that I'm missing.

I have had a 2005 f150 v6 5 speed for a little over two years. Got about 153k on it. Last night was sitting in a parking lot idling about 20-25 minutes, went to leave and she started sputtering hard, lost all power and died. Started back up, idled fine, as soon as i put it in gear same thing then the check engine light came on.

Every so often, my manual transmission Corolla will "overthrottle" during acceleration, especially shifting into 2nd and 3rd gears (and sometimes even 4th), i.e., the engine will race above the usual RPMs associated with each gear, just for a bit. This however, isn't consistent. I still need to check if the engine air filter is dirty, which I suspect could be a part of the issue.
The vehicle has ca. 124,975mi, and only started exhibiting this problem 2-3 months ago, and only in 2nd gear. Again, this issue is very intermittent, and sometimes I can go a week or two without any incidents at all. The regular maintenance (oil changes, cooling system maintenance, etc.) has been faithfully performed according the manufacturer's specifications.
