Ford 7.3L Power Stroke (1999-2003) :: 2000 - Occasional Miss At Highway Speeds / Bucking And Jerking During Even Gentle Acceleration

165k miles 4x4 6 speed, bone stock unmolested

Slowly progressing problem over 6 months. Occasional miss at highway speeds uphill has progressed to bucking and jerking during even gentle acceleration attempts.

I hadn't got my cam sensor recall done but no change after that procedure completed yesterday. Oil recently changed as well.

I have a torque pro but it never finds any fault codes even though 'service engine' light comes on sporadically. I'm not sure I'm operating it properly but it at least reads rpm when its running.

I'm contemplating the hutch mod but I'd like to have an official diagnosis beforehand if its possible in my case.

Ford 7.3L Power Stroke (1999-2003) :: 2001 F350 - Power Loss / Hard To Hold The Speed?

I drive a new to me 2005 F350, he has a 2001 F350. While we were talking he said he didn't think his pickup had the power it should have. He pulls a 5th wheel camper that weighs around 8000 pounds fully loaded. He said it takes a couple of miles to get to 55 mph, and it is hard to hold the speed. It doesn't have the power it did when he first got it last year. He was told that a diesel is slow getting started. He rode with me in mine, when I dropped it about half throttle to pass a slow car he said he could tell mine had way more power.

His check engine light is not on, it starts good both when hot and when cold. It runs smooth, no miss as far as I can tell listening to it. What are some common issues that could cause this? He did just change the oil and fuel filters, not sure about the air filter. He said the power loss came before he serviced the engine, and did not improve after the fuel filter change. Where to start? He was also told to check the filter inside of his fuel tank, so he is getting ready to drop his tank.

Ford 7.3L Power Stroke (1999-2003) :: F350 Will Hold Back Sometimes And Not Increase Speed

I am having trouble with my 1999 F350 Ford Powerstroke, Looses power but the motor never quits and also starts up fine, will set and run and warm up on the coldest morningIdles fine, It will hold back sometimes and not increase speed. I can take it out today and it may be fine and tomorrow can't run 2 miles. I was thinking CPS but after reading information I am not sure. What may be causing this issue. I just put a High Pressure oil pump on it could this have anything to do with it. Was not having a problem before the pump was changed. The pickup has 190,000 on it actual miles.

Ford 7.3L Power Stroke (1999-2003) :: Smoke For About 10 - 15 Seconds Pretty Heavily When Slow Down After Highway Speed Driving

Been barely driving my super duty due to it having a multitude of issues. So working on getting this thing back to some semblance of running decently and it has been smoking whitish blue, oil smoke out the exhaust. Not constantly, intermittently as far as I can tell.

If I drive it at highway speeds for 5-10 minutes then slow down it will smoke for about 10-15 seconds pretty heavily. Yesterday I got off the beltway after running for 15 minutes, it didn't seem to be smoking, but about 1 mile to 1 and half miles later, pulled into a convenience store and it was like I was spraying for mosquitoes for about 20 seconds then cleared up.

Truck seems to be running strong. Turbo doesn't seem to have any play side to side or in and out(according to Baltimore Performance Diesel who I don't necessarily trust at all [ I will explain my reasoning on that some other time, but let's just say, one of the reasons involves a rear main seal diagnosis... I digress] but I assume they are correct on that, I haven't looked myself. So what are some other possible answers, rings I would think would be fairly constant but I could be wrong there.

Ford 7.3L Power Stroke (1999-2003) :: While Driving F250 Start Chugging / Lose Power And Shut Off

I have a 99 F 250 7.3. It runs fine at idle even for a long time. When I drive around the block a couple of times it will start chugging and lose power and shut off. I have been mixing fryer oil with the diesel. I changed the fuel filter, oil change, crank sensor and fuel pump. I added 15 gallons of diesel and diesel treatment. Pulled fuel filter and bowel is full I'm not sure where to look next.

Ford 7.3L Power Stroke (1999-2003) :: Engine Missing / Bucking At WOT

I have been having a problem for a while now where my truck will miss/buck at WOT. This only happens at higher RPM's. From a standing start 0-60 it is fine. However when I downshift full throttle from about 50 MPH it initially goes, but then it will miss/buck consistently until I back off the throttle.

I have so far replaced the CPS, re torqued injectors, checked valve cover harnesses and fuel pressure stays in between 64-58 full throttle. No codes show up.

My truck runs great except as I described above. I would think an injector or two are bad, but the truck runs and idles great. My initial guess was that it was a fuel pressure issue, but fuel pressure holds strong. Could it be air in the fuel?

Ford 6.0L Power Stroke Diesel :: 2003 F350 - Rumbling At Highway Speeds

2003 f-350 6.0 4wd dual rear wheels
4 inch superlift suspension lift, dual shock steering Stabilizer
33 inch wheels.
4 inch turbo back exhaust
Other than that it's really bone stock

Here's what's going on. In 2wd, between 55mph and 62ish mph, once I hit a constant speed, a rumble beneath my feet emerges. If I either speed up or slow down, it immediately goes away.

Does the same thing in 4wd high.

I can eliminate front drive shaft and u joints seeing as they shouldn't be turning while in 2wd. I did notice that when I push up or side to side motion in the front drive shaft, there is a click and a bit of motion. Is that normal? Just a side thought.

When i take off there's a bit of vibration from the rear half of the truck, but I've isolated that to the center support bearing. With all this being said, none of these symptoms were around before I lifted it.

Ford 6.0L Power Stroke Diesel :: 2003 F350 Shakes At Highway Speeds

Have a 03 f350 with the 6.0 have been experiencing very harsh shaking problems. This only happens at highway speeds 55-60 any other speed is smooth as can be weather it's 25-95 mph. The weird part is that it only shakes when the truck shifts into overdrive and it shakes bad and if you lay into it like you were gonna pass someone it stops then shifts back into overdrive and shakes again.

Ford 6.7L Power Stroke Diesel :: 2011 F350 - Won't Start / Chugging Sound?

Just went out this morning to start my 2011 F350 diesel and the starter is doing a "chugging" sound. Not spinning the starter at all. Just turned 60,000 miles last week and this is the very first issue that I have had with the truck.

I have put a trickle charger on the battery on the drivers side, and plan to leave it on for an hour or so.

Ford 7.3L Power Stroke (1999-2003) :: 2000 - Truck Started Bucking When Rolling Down The Freeway

2000 Ford Excursion, 7.3 PS with 210,000 miles. I am on I40 at a truckstop. I was rolling down the freeway last night when the truck started bucking. I pulled of the freeway and here came a thunderstorm. I waited til this morning to check for codes cheap scanner. I pulled a code P1211. I waited for NAPA to open so I could take it in the shorts. I bought a fuel filter and an ICP sensor. After changing them out, the truck runs then starts missing. My battery is about to die so I will finish post shortly.

Ford 6.0L Power Stroke Diesel :: 2006 F350 - Bucking / Rough Running

2006 F350 6.0 ... I am piling up parts for a bulletproof party later this summer. It has gotten grumpy ahead of schedule. I will hook up the AE tomorrow for consultation.

In the meantime. Running rough at 50. Seems to accelerate from a stop semi ok. Sitting at idle, holding rpm at 1750 I hear kind of a thump under the hood and the rpm drops 300, then slowly finds it way back to 1750 and it repeats itself.

This thump has not been noticed in the past. Could this be the VGT not working as expected?

Santa FE SM (2001-06) :: 2003 V6 Engine Chugging And Bucking / Belt Slipping Whine

MY 2003 Santa Fe is fwd with the 3.5 v6. While under normal conditions, the engine lost power and began "chugging" and "bucking". There was also a belt slipping "whine" associated with this problem. The problem continued for about two minutes, then corrected itself, and I was able to drive normally.

Ford F-150 (2004-2008) :: 2005 - Occasional Bucking / Shuddering When Slow Down From Highway Speed To About 30mph

I have a new to me 2005 F150 SuperCab Lariat 4x4 with 155,000 miles on it. About a week ago I replaced the from passenger hub assembly and half shaft (torn boot). When doing that, I noticed that the IWE actuator was not working right (would not compress evenly). When taking that off, there was a bunch of rust that came out of the vacuum line ports. It started moving freely after cleaning all of that out that I could (I will be replacing it soon). I assembled everything back together and all seemed OK mechanically.

I also scanned the truck and saw the code for a bad IWE solenoid so that is being replaced tonight. I also have not checked the drivers side yet.

So...now that I have done all of that, the truck started occasionally bucking/shuddering when I slow down from highway speed to about 30mph and lightly accelerate again. It does not do it every time though. There is no grinding/whining noises either. Could this be caused by the IWE system somehow? Maybe slowing losing vacuum and having one engage and the other disengaged?

Ford Super Duty (1999-2016) :: 2007 F350 - Steering Play At Highway Speed Only?

I have a 2007 f350 scsb with the 6.0 that has 131k miles on it... I bought it in December at 125k and since I first got it I've noticed a lot of steering play at highway speeds only... Basically 60 mph and up... I have a hard time switching lanes and passing because it's very unpredictable just how the truck will behave... It feels like the steering is loose but also slightly delayed and when I make slight adjustments it feels like the truck overcorrects itself... Could this be a steering box issue? A power steering issue?

Ford 7.3L Power Stroke (1999-2003) :: Truck Shuts Off When Going Down Highway

Headed to town with the kids and my truck shuts off going down highway. I pull over and start it back up and make it to 30mph and shuts off again. This time it will not start. I have 1/4 tank of fuel, I first thought it maybe the issue inside the tank causing it to shut off. I get some diesel pour it in and it fires up for about 15 secs and shuts off. I pull the fuel filter, making sure o have fuel in the bowl. Start it up and it runs for about 10 sec. I then swap out the CPS. Same thing, runs about 20 and cuts off. I then call AAA because I am tired and ready to go home. I have it towed to my buddy's shop. He has not looked at it yet.

Ford 7.3L Power Stroke (1999-2003) :: Died On Highway / Would Not Start Then Fired Up?

I was driving on highway about 55MPH when I lost power suddenly. I was able to pull off, but did not have power brakes or power steering. Gas tank was near 1/4 gallon on the gauge, but sometimes my gauge is wrong, as I've run out 2x when I should have still had a few gallons in it.

At first I thought CPS, but I didn't have a spare with me to swap. Well, after an hour or so, I cranked it, and it would turn over but not even try to start. I floored the gas pedal and it fired up and I was able to get home.

During the no start issue, there was no oil pressure reading on the gauge and the tach was not moving, even though it was turning strong. There was no white smoke that I could see either.
