Ford 6.0L Power Stroke Diesel :: 2006 F350 - Accelerator Pedal Too Stiff
Oct 19, 2013
I have a 2006 F350 Crew Cab with the 6.0. It is used primarily for towing a fairly heavy 5th wheel RV. I find that the accelerator pedal pressure is much higher than any previous vehicle I have ever owned. The problem is magnified by the fact that I have a previous ankle injury that makes it very uncomfortable to have to press on the accelerator so hard for long periods of time.
I try to use the cruise, which sometimes works on flat ground, but the shift point at my desired cruising speed is such that the slightest grade will make it downshift. With the cruise off and my foot kept at a constant pressure, the truck pulls up the slight grades just fine with no significant loss of speed and no downshifting.
Is there any way to lighten the pressure it take to push down the accelerator? I know it is actually moving a throttle position sensor, but is there also a pedal return spring here that is too stiff for me?

I have an issue with my 1999 Ford F350 7.3L diesel and stalling when the accelerator pedal is pressed and released.
Background: Initially the truck would not start, and from there here are all the things that I found wrong and replaced. (keep in mind that I troubleshot all the issues and every part that was replaced was proven faulty)... Starting with the glow plugs, all but 3 were faulty and not making a connection to ground. (only one broke off in the head, but I was able to get it out with out getting anything in the cyl)..
Valve cover gasket and harnesses, this is to include replacing the connectors on the engine harness cause both sides of the connectors were broken. The ICP was leaking into the connector and breaking the connection to the PCM, so the connector was cleaned and the sensor replaced. No issues from that now.
The IPR was replaced cause the oil pressure was erratic and not stable when I had my pressure gauge hooked up testing the pressure. After that was replaced the pressure was ok, and it climbed with RPM's and fell back down like it was suppose to. I could not get the PSI up to 3000 PSI even at full RPM's, but it did not drop past 600 psi.
The fuel tank was recently replaced, and all the fuel was removed and "fresh/good" fuel was put in. The fuel bowl was cleaned out and the filter replaced. (the fuel bowl did have a lot of crap in it like rust and dirt). Fuel pressure was at 95 PSI last time I checked, which is higher than the recommended 60 to 65 PSI.
That being said the engine did start and run, but was very rough and missing. So I did all the injector o-rings. Some o-rings were starting to split, and others were not sealing like the copper washer on the injector tip. I could tell by the amount of crap in the end of the injector. ( not the tip, but where the injector contacts the injector cup. There must have been water in there or something cause that part had all kinds of crap around it)
The engine smoothed out after a couple day of running it, but it would still stall when it was cold. The block heater was replaced cause it was falling out. The oil was changed and the filter too. The CMP sensor was changed just because I know they will cause the engine not to start. I had a "known good" truck that I can swap part to and from, and I did a lot of that thus far.
Swapped the IDM, PCM, EBP sensor, MAP sensor, all relays inside the engine and in the cab. I was looking for the barometric pressure sensor, but from what I have read thus far that is a calculation in the PCM between the MAP and the EBP sensors. The diode to the PCM is good,I checked the harness for rubbing by the 42 pin connector and by the LF fender but I did not find any chaffing or rubbing on any wires. The ECPR was wired together, so I fixed it so that it is no longer that way, and the waste gate for the turbo was wired open. I took the wire off and made sure the linkage worked and it did move. I tried to lube up the valve in the turbo for back pressure, but I'm not sure if it worked or not.
I also swapped out the oil pressure sensor and the oil pressure temp sensor on the HPOP Reservoir, and blew out the EBP sensors tube. (air went straight through the tube with no restrictions.) I did a buzz test and all the coils checked out ok. I also did a contribution test and only three cylinders were identified as having some kind of issue. (but this is not enough to cause the engine to stall..) The only current codes that I have are the air intake heater, and the EF feedback not detected. Neither of which would cause the engine to stall in my opinion.
Symptoms:
When cold: The engine will start and idle just fine, but when the accelerator is pressed and held to 1000 RPM's the engine will sputter like its missing and surge up and down between 500 and 1100 RPM's. If the accelerator pedal is pressed quickly the engine speed to increase then fall down and stall. It seems as if the PCM is shutting down and starting back up. ( Like the key is turned off and then back on quickly, but the engine doesn't recover)
When warming: This issue becomes more erratic, but when hot the engine is fine. No issues, and it will drive all day long with no hesitation.
The truck has over 200K on it, but I know it will go more! It is a mannuel tranny, and is a 4X4, and I love it, I can't get ride of it just yet.

i have a 04 ford excursion 6.0 with the egr delete, was stopped at a light to make a left turn, when i stepped on the accelerator pedal nothing happened as the engine was just idling. i pumped the pedal around 10 times and finally got the engine to rev up. i just got this excursion and don't know to much about the maintenance on it. i am going to drain the water and change the two fuel filters. my neighbor is familiar with diesel engines and he said to look at the throttle sensor. i have run this engine up to 900 miles and it has started and run perfectly. i believe the usual maintenance like oil changes etc were done on it. would any error codes show up even though no warning lights on the dash.

While driving the other day, the truck suddenly began to stall when pressing the accelerator. The water in fuel light came on as did the glow plug light. This continued with the truck sometimes dying all the way and other times just stalling then picking back up. No difference in throttle pressure seemed to make a difference except that letting off totally then slowly pressing seemed to let it keep running sometimes.
So I get home and drain the fuel water separator. I gets about a thimble full of water and lots of the rusty looking junk others have talked about. Try to run the truck again, same thing as before. I then changed fuel filters and thought that had it licked but after about 10 minutes it started again. By the way, the 6mm plug seemed to have about a third of the threads rusted off. Not sure what that means as I drain it at least twice a year.
I have read a lot about the ICP and IPR issues and was wondering if this could be my problem. I am hoping its not the HPOP. My other thought was something in the fuel tank blocking the in tank filter. I checked the top mount bowl and it was only about two thirds full after running the truck

Does the 2015 F350 have the dead pedal on the left drivers side? The one they used to put in to rest your foot on?

My 2001 Hyundai accent hatchback with around 135000 miles is having problems with the gas pedal. I start my car and can't really push down the gas pedal smoothly. It is initially hard where I have to slightly kick the pedal to move it. Otherwise if I rest my foot on the pedal and try to press it down I end up press it down too much where my car goes flying. Every time I come to a stop I have to do that to get the pedal to move. Its not stiff once I get the pedal to push down some but once I take my foot off the pedal I have to slightly kick it back down.

I would like the hear what others have to say about the problems I'm having with my 2006 F-350 sd xlt 6.0 with 113,000 miles on it. It's being used as a tool truck mostly going from a shop on the property to close by buildings on the same property. In other words very short distances. Used occasionally to take a dump trailer to a close by dumping ground.
1. White smoke from exhaust. I've read this is most likely an ERG cooler that needs replacing. Any other possible causes? If I end up having to replace the cooler is there a stock cooler that is reliable or should I get the one by bullet proof?
2. Diesel is dripping from the muffler weep hole. Last full tank lasted only 60 miles. Could this be the oil cooler? Anything else? If so is the Ford replacement cooler OK or should I go with an upgraded cooler?

So this '06 F350 is blowing fluid from the steering pump fitting when you move steering wheel to either side all the way(lock). Is the internal o-ring blown in the fitting? Do these have the teflon seal at the pump? Pretty new to the 6.0 scene. Got a new line ordered.

I have a 06 f350 superduty with a 6.0 I have had injector problems before with the motor even hydro locking no start this is the problem my truck started blowing white smoke with a strong diesel smell everyone said it was oil cooler but I took it to a ford garage the guy said I had 2 injectors hung open and wasn't hydro locking and suggested to put all 8 in so I did 3400.00 not I went to pick it up had no power at all turbo was not kicking in so I took it right back to them they checked it out said turbo was sticking had to clean it it would take 6 hrs. said the fuel In the motor caused it it was working fine when I took it to them now they say maybe a new turbo are they giving me the run around or is this possible....

I have a 2006 f350 4x4 dually 6.0. The other morning when leaving for work I hard a loud air noise, like a jet. It only happens when the motor is trying to create boost. I have NO boost. No smoke. If I push the fuel pedal past 1/4, nothing. Its like its stuck and no more power at all. I have changed the boot from the turbo to the intercooler pipe. (looked like it had cracks in it). Checked the cold pipe, no cracks seen. Check the exhaust clamps, into the turbo, they are tight. The turbo is seeping oil around the seal. I took the inlet, fresh air, pipe off. Check the turbo spool for looseness, fins, spun the wheel, ran the engine and watch to wheel. Seen no issues. Where to go now?? No coolant leaks, no oil leaks.

My dad recently bought 2006 6.0. He has had it about 2 and half months. Has the egr delete kit installed. The truck has ran great. Up until Wednesday the 3rd. My dad headed to Ut to pick up our new quads. While heading up a small grade with empty trailer in tow. Truck went to limp mode, fan kicked on, orange wrench came on on dash board. He pulled over let her cool down turned her off.
Checked fluids Then started her back up and she was fine. That has happened 3 times. Now he is on his way back (tow haul mode turned on) and it is doing it again. She hasn't went into limp mode yet. As soon as the fan kicks in my dad pulls over immediately and puts it in park. And lets her cool down checks fluids. This issue only happens mid way up a grade. So my question is...... What is causing this? How do we fix her and make her a happy truck again.

I drive an 06 f350 with a 6.0 diesel. My truck has quit on me twice in two months. It lost power then stalled and would not restart. I had just changed fuel filters but checked them anyway to see if they were plugged. They looked clean so i put them back in and the truck fired up. It ran good then two months later it did the same thing.
I noticed I could not hear the fuel pump so i pulled the cap off if the top fuel filter to see if there was fuel in it, and heard air being sucked in (or pushed out?) as i loosened the cap. I put the cap back on then turned the key and i could hear the fuel pump working. I waited for glow plugs and it fired up. Is my engine getting vapor locked, or sucking air? If so then why would it only happen every now and then instead of continuously?

This truck is bone stock FYI. I get in it to crank it and I get nothing. Batteries are good, everything in the cluster lights up, and looks normal. No codes are thrown. I can hear the solenoids click under the dash and hood. I check the voltage of ignition cable at the starter and I get no reading.
There is a single thick yellow with light blue stripe coloured wire on the passenger side of the engine compartment, beside the vacuum pump with a "squeeze and pull" type disconnect. Disconnect it, and connect the male half of the connector to the passenger side battery positive terminal. Do this with the ignition key in the RUN position. Does the truck start?
This is where it gets weird. The truck does start and after i reconnect the wire it it starts normal. I started it several times throughout the day. The next morning I get in the truck. No start. I have to use the wire and manually connect it to the battery and it starts right up again. This time I get a "Tow/Haul" light blinking on the dash. It will go into gear but pressing the acceleration pedal does nothing. I turn it back off, attempt to start it normally and it starts right up. No it will go into gear and drive. Now I am thinking maybe the neutral safety switch?
Could it be a solenoid sticking or the neutral safety switch or something else entirely?

I have a 2006 6.0l f350 crew cab that blows air hard every time I accelerate. Sounds like you're going 100mph with the hood unlatched. It blows real hard for a minute and goes away if I accelerate through it or let off.

I was just wondering, is it normal when plowing to get stuck in the snow? Last year I got stuck and had to get pulled out, yesterday I got stuck again and when I have it in 4x4 hi, one front and one rear wheel spins. 4x4 low, the opposite front and opposite rear spin from hi. I want ALL 4 WHEELS TO SPIN! I'd NEVER get stuck if that happened! How do I get that to happen? I hear of a detroit locker. Do you need one for each wheel? I always thought as I was flying past everyone in the snow with a huge smile on my face, that all of my wheels were powered.

Went today to check out a buddy's truck, 06 F350 164k egr and cooler delete. He finally did his thermostat yesterday, after not having warm heat for months. Today on the way to work, had great heat for about 10 miles, then it went cold. Pulled over to check coolant, cracked cap loose, let pressure out, now had heat again. Same thing on the way home. Had the white streaks down from the cap, lost a small amount of coolant, just at min line now. He's owned this truck since 48k and no heads have never been off.

I bought an 06 6.0 f 350 4x4 dump bed cheap. seller said it was sitting for 1-2 years and wouldn't start. ficm is at 48 volts fuel pressure is at 100 oil pressure builds fine, then checked compression and reading no compression in any cylinder. My mechanic says new motor or possibly both head gaskets are blown.

I just wanted to share with you all a cautionary tale about belt tensioners and idler pulleys. I am now a firm believer in installing the aforementioned items when you replace your drive belt. 15000 miles ago I replaced the drive belt and didn't heed the warning of some here on the forum.
For the last month or two I have noticed what sounded like road noise which I dismissed because I had just had new tires installed that had a more aggressive tread pattern than my previous tires, I also noted that the ECT had been a bit higher than normal, like running in the high 190's to low 200's on average.
Well while driving today I get the alternator warning light and lose power steering and soon after the brakes got stiff, this was followed by ever increasing ECT which got to 242* before I could get it off the road and shut down. It is too early to tell if the noises and the ECT temp rise were the result of this tensioner going out...
For what its worth the only tools required were a 10MM end wrench and a bit of skin to get the job done.

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?

I have a 2006 F-350 4x4 CC LB. I recently had my check engine light come on coincidentally on my way to the auto parts store. Asked them to plug in the scanner and read the code. It had around 20! This truck has 40000 miles on it. All of the codes were dealing with injector voltage being low. All eight cylinders. So I'm thinking ficm is going out. I replaced the batteries shortly after this. I driven it a time or two after this and it started cutting in an out going down the road. Seemed down a few cylinders for a few seconds and pouring black smoke from the tailpipe of a stick truck. Made it home after it did this there times. Stated it up to move it a few days ago. Some white smoke that clears quickly and ran rough for a few, pulled it in gear surged forward and died. I cleaned the EGR valve and re o ringed it. Tested the drivers side pin on the FICM and have 47-48 volts with key on and cranking.

I recently purchased a 2006 f350 with 6.0 power stroke. I drove it approx 15 miles shut the truck off, let it sit for approx 3 he's. Then I drove another 15 miles and shut it off. When I went back to it. To start it up would not start. The dealer said brand new injectors when I bought the truck. I tried to start it for approx ten min. I didn't want to bog down the battery. So when it wouldn't start I sprayed a shot of starting fluid and it took right off. But when you shut it off it won't start again.
