Ford Super Duty (1999-2016) :: 2004 - Running Rough Both At Idle And Driving - Truck Shakes A Lot At Lower RPMs
Jan 9, 2015
I have a 2004 SD with 5.4 that is running pretty rough both at idle and driving. Truck shakes a lot at lower rpms. I have a scan tool and had a misfire on cylinder 4 so I replaced the coil and the plug. Also replaced the idle air control valve. Plan on replacing O2 B1 S2. (One of my codes) even after replacing the coil and plug I'm still getting misfire detected from cylinder 4??? Other codes I had were misfire detected on he first 1000 revolutions. That hasn't come back though.

V-10 running rough at idle, chugging. a problem has developed with my 2004 E-350 V- 10 after having a new fuel filter installed and the induction service done . Picked it up from a local shop and it was running rough after bringing it in when running great! I figured maybe it fouled a plug or something so I drove it home but it didn't improve so I brought it back and had new plugs installed. It is still running rough and wanting to almost stall when accelerating from a stop and the shop cant figure it out , not showing any codes.
I'm thinking maybe they caused some type of vacuum leak that is so far undetected. The killer is it came to the shop running great !!
No other problems with the vehicle, I drive it every day and have owned since new. 278,000 on it now and it has been the best vehicle I have ever owned.

It's an 04 F350 6.8L This past winter when it was cold I would start it up and it would rock forward and bounce back as is you shifted in to park while rolling. Now that it's warmed up it won't jerk forward but the whole body shakes only at start up. As much as I like the idea of of the raw torque being so powerful the truck twists with power I don't think that's the case.

I got a 2000 f250, 5.4l, I got a check engine light bout 2 weeks ago and didn't experience any driving issues. The code was p0171, just recently I've been experience troubles idling, if I let my truck idle for about 3 minutes it will want to shut off, also on acceleration the hole truck bumps, feels like I'm in an earthquake. Where I should start with this problem?

Let me start with I have a 2003 f250 5.4. The motor blew on my truck and I had a 100k motor dropped in it. I've put new spark plugs, ohmd out the coils. I tried both sets of injectors. cat delete and new fuel pump. It has rough idle and stalls but runs fine at higher rpms. Also has basically no brakes. I am thinking vacuum but I've check all the lines. No codes either!! also cleaned throttle body.

I have an 02 f250 V10 with a rough idle (90K Miles). It's not horrible but it's obviously not running perfect. Everything seems ok when I am up and driving, especially at freeway speeds. I recently noticed that if the truck is in park and I run the RPM's to 1500 or 2K and quickly let off the gas it will die. It never throws any codes. So far I have replaced the IAC Valve, fuel filter, O2 Sensors, PCV valve, cleaned the MAF sensor and replaced the air filter. Plugs and boots were replaced 5K miles ago. Fuel trim levels on both banks are running around -3.1 to positive 3.5 based on what the computer is telling me. Also according to the computer the vacuum sits steady around 25 at idle (+ or - .2). I don't have a manual vacuum gauge, just relying on the computer. I've also gone around to every plug and disconnected both the injector wire and the COP wire and they all seem to equally affect the idle as well as the fuel trim levels.

I have a 99 F350 with a V10. I just replaced all the spark plugs and a bad coil which solved the very bad misfire I had going on. I also just changed the fuel pump and fuel filter.
When I start the truck, it idles just fine, nice and smooth. After sitting there for a short bit, maybe a couple minutes, it starts to idle rough, not so rough that it's about to shut off, just a little rough. This lasts maybe a minute and then goes back to nice and smooth and stays that way.
I've thought maybe the EGR valve or Idle air control valve but I'm not sure if I'm way off or sort of close.

I have a 1999 F250 SD V10 4x4. I recently had a transmission installed and the truck is running erratic. I have an engine miss (sometimes when idling, more so when in drive and foot on the brake). I say sometimes because there are times it will not miss and the engine runs smooth. The transmission shifts a little strange and sometimes hard.
I am getting a code reading that says my TPS is faulty, but I installed a new one a few months back.
The engine is running rough (jerky on acceleration) especially when driving. I was wondering if I should take it to a shop and have them flash the computer to reset it?
I also remove the AC compressor a while back (bad clutch). I installed an aftermarket pulley.

I have a 2004 f250 6.8L and recently I've notice the trick not running strong. Is hesitating when i step on the gas pedal. For example, I am driving on the feeder road and fixing to get on the freeway ramp, well i have to spent a bit harder on has pedal to gain speed, but it seems its struggling and I can hear muffler making like a flapping noise. Also when I am going between 40-65mph and I spent on it, the tricks kind of jerks and vibrates. Feels like its coming from transmission. I let go and step on it again and it goes away. What to check??
Miles : 96k
Year: 2004
No Check Engine Light

I have a 1999 f350 7.3. I'm having a problem where the steering wheel shakes back and forth and the whole truck wobbles. It happens at all speeds, but shakes faster at faster speeds, slower at slower speeds. At first the wheel was just jerking randomly but then I made a right turn, heard a pop, and then it was shaking like crazy. I jacked up the truck and checked the ball joints, checked for and play in the tie rods, and turned the wheel left and right. Everything seems ok so I can't figure out what is causing to wheel to go back and forth.

1999 F250 7.3 240k miles .... This is the second truck to act like this on me after I cleaned the in tank filters.
I had to cut the fpr spring to 30lbs for the truck to start fine cold and idle ok but has no power. When hot it wants to die and or dies at idle and has next to no power. ( I'm guessing from lack of fuel) but it's the only way for me to use it. With a new spring and 60ish lbs of fuel pressure, they won't even start.
I cleaned the in tank filters. New fuel filter. new oil. rebuilt the ipr. unplugged the ipc. no loss of boost. checked my uvch, wiggled all harnesses with no difference. I also tried dropping the tank again in case I pinched the return line but that made no difference.
I'm guessing that I need new injectors. I'm not close to anyone with a computer nor can I afford to throw away any more money at the moment.
Totally stumped and cannot seem to find a definitive answer online so far. Both trucks ran somewhat ok before and got worst once I dropped the tank and cleaned the filters which increased the fuel pressure. This is my second truck to act this way.

Yesterday my mom used my car and the battery light came on while driving, but she didn't really care about it and was driving the whole time on the battery. When she came back home the car was barely even alive I couldn't even start it. I replaced the alternator (duralast from auto zone) and the serpentine belt, but now I have a very rough idle and the rpm's are lower than usual. They are 1500 instead of 1750. Is this normal and eventually it'll go away or did I mess something up?

Ihave a 2004 F350 4x4 Dually diesel. While in my hay field I hit a small rut and the truck bounced. About two seconds later all gauges and lights/windows quit working and the truck ran rough. I have a Banks system and it registered a code 33. Maybe 32 error. Book says it is an airbag deployment. They did not deploy. So I drove out of the field and turned it off to see if that would reset the gauges. No, not only that but the gauges all swept the faces from off to full to off and the truck would not start, just chatter.
I disconnected both batteries and waited. Reconnected and it started, but the gauges quit after 10 seconds..... Everything flatlined even the banks IQ. But the truck kept on running. Got back to the ranch and the batteries went flat overnight... Charged them up, starts fine gauges work but alternator puts out 11.5.

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 ....

On my way into work this morning, my 06 with the 5.4 started running very rough/shaking at low rpms. I could kick it out of overdrive and it would smooth out and seemingly be fine at higher rpms.
This worked out for a couple of miles until the truck just died on me completely. The Edge is showing po351, 352, 353......358 codes. Ignition coil Primary/Secondary circuit fault on every cylinder.
I'm thinking its unlikely that every coil failed simultaneously....computer? When I try to start the truck, it will try to hit on a cylinder or two, but will not run.

Just changed the oil in my 6.0 and I'm sitting here looking at my tuner and is telling me my idle rpms are about 770.
Before I changed my oil it idled around 750.
It's running fine, I was just wondering why it changed? More pressure to the injectors with the newer oil?

I have a 2004 to 250 super duty 5.4 and automatic trans it has about 233,000 miles on it. Yesterday when I started my truck I could see my reverse lights were stuck on against the garage door in the dark. After I put the truck in drive the lights went out later on I shift at the truck and to park and the starter engaged I put the truck in neutral and it stopped the starter from running after doing that several times the truck now does it even when it's in reverse or neutral. I have to leave it in drive and push the emergency brake on I am in and out of the truck all day long. I did change the shift to blast may I check the screws on the back of the shift to bury thing seems fine.

I'll try not to post an entire book.. But I bought a 2000 F250 not even 8 months ago, it did have issues before but I changed out the spark plugs and coils and it fixed it's original missing issues.. I also just recently changed the fuel filter but it didn't fix it's new problem.. It drives ok around town but if I get over 35 mph it doesn't run well... If I try to keep a steady foot on the gas but don't get the RPMs over 2000, the RPMs will stay where they're at for just a second then they will drop down and the whole truck starts shaking.. I push more on the gas and it shakes even more and the RPMs don't move at all until I really step on it.. It lacks in power going up hills as well... The dealership i bought it from said the Catalytic Converter was bad but my uncle who is a mechanic says it isn't.. It's the first vehicle I've bought so kinda wanna make it last..

My wife was using my truck and she felt it lost power and ran rough, so she pulled over can contacted me. We both are deaf, but I can hear some and it sounds really bad. So, I had it towed home and I recorded it.

I've got a 99 f250 5.4 that runs like a top. In the last 6 months I've been chasing a little problem. It doesn't happen all the time but seem to be happen more and more. While driving any speed If I let off the gas the RPM's hold at around 1500 then surges down to 1000 then back up again to 1500.
Does that 2 to 4 times then all good. Give it gas again it does it again. It kind of does it when it wants. Could be fine for a trip around then next trip it acts up again. Checked a lot of the vacuum lines, PVC valve and replaced the idle control next to the EGR valve. EGR is next.
Idles and runs fine except the surge thing..
P0401 code as well.
