Ford 6.0L Power Stroke Diesel :: Lack Of Power When Going Up A Hill On The Interstate At 2800 RPMs
Aug 2, 2016
While I'm cursing at highway speed everything is fine. But when u punch it it pass someone it's like I actually slow down, same from a red light. I've got a livewire programmer in it and this problem is somewhat new. It just seems to keep getting worse, I was going up a hill on the interstate this morning and at 2800 rpms I was actually slowing down. I'm not sure if the fuel pump is going out or if the transmission is slipping or what.

I get what I can only describe as a "missing" when Im on the interstate just cruising along with rpms below say around 1900. That seems to be when I have noticed it. It is not very frequent but often enough to not let me forget about it. Happens when I'm towing it seems more than when not. Seems the rpms have to be below 18-1900 and in 5th speed. You can just feel the truck ever so slightly missing like in the old days of points and distributor caps. No tunes

I purchased my 2013 F350 PSD July of 2014 and immediately noticed "the shudder" when the engine was lugged down to 1000-1100 rpms on a hill. Sounding like somewhere around the turbo belching air too. At first I was startled but learned to manually downshift to higher rpms and it will stop. Once or twice I tried accelerating out of it and it shuddered as bad as the poster who said it made the steering shudder too.
My truck has 16,000 miles and I never let the rpms drop now. So I figure I have a real problem I'm not imaging. What should I tell my dealer is the TSB or remedy ?

I was driving and my truck started have lack of power, could barely get going on hills, tons of blue smoke (smelled like diesel) real rough idle. I unplugged injectors and found #5 made no difference. I replaced it today and I can't get it to start. It'll get to 2000+ psi 48v ficm, low pressure oil registers, ficm says its in sync. It will crank and blow a lot of black like its half firing or something. It has even crank to, until it tries to fire. From what I've been reading could it be the ficm? That one circuit is fried?

I have a 2003 with 150k miles. My 6.0 has black smoke and can barely crawl up a hill. Dealership is 30 days out for an appt. Air filter, oil change, alternator, and batteries are new. I removed the EGR valve and cleaned, but the valve seat is not perfect. I can see 20 to 30 mil gap around half of the seat. Is this ok or will that little gap cause this?
Hoses all look good. No alarm lights. I have no diagnostic tool but I can use a meter well. It did have an airbag light but I found the fuse missing and replaced it. The air filter alarm switch fell apart but I bypassed it till I get new part. No alarm lights now.

Blown fuse causing a lack of power to the OBD port?
I just got my Kiwi2 BT OBD2 adapter and was hoping to start diagnosing my truck, but the adapter won't power on while connected to the truck.
I pulled and visually inspected fuse #12, I also verified power to the cigarette lighter plug and the accessory 12v power outlet.
The adapter powered up with no problem when I connected to a co-worker's Tacoma.

I have a 2004 f350 with a 03 bullet proofed motor. The truck did not have any power and the turbo wouldn't support until I put a new vgt solenoid in and it ran great for about 3 miles... Stalled doing 65 kinda lacked power while accelerating but got up to speed quick. I pulled over and no start. It is running error code kam on pcm from disconnecting batteries but could this cause the stall and no start? Or should I be looking into icp sensor?

Having some problems with an e-350 dying when in gear and rough idle. Truck starts up after it dies. Vehicle acts like it is starving for fuel. I have check fuel pressure after fuel pump and getting 55psi. High oil pressure pump with in normal ranges. Cleaned and checked egr and it was in the closed position. Fuel filters have been changed. Injector buzz test ok.

My 2007 6.0 has a really rough (almost 'miss') during cold start up. After 5 seconds or so, it smooths back out and sounds normal. Until gauge reaches normal operating temp - there is a surge/lack of power during light acceleration. I also hear a frequent compressor coming on and running for a while which I am contributing to a possible vacuum leak. Maintenance is always done on time and I've already had a few costly repairs (both internally as well as externally) on the engine. I usually always wait for the glow-plug indicator to turn off before cranking the engine and let it idle for 5-10 minutes prior to driving it. Once the vehicle climbs to normal temp. everything seems to be fine but the compressor still comes back on every so often.IS it worth simply replacing the vacuum canister located behind the passenger side battery - or should I find someone to hook up a diagnostic unit first?

EGR stuck????
CAC boots look good do not hear any leaks on the tubes
no smoke
ICP 675 at idle full temp, cold 1200
OEM filters with OEM caps
ficm 48.5 to 47.5
Can hear the turbo spool up
Oil temp less than 10 dec difference with water temp
No code showing up

I have a 2006 F250 6.0 Amarillo Edition. 133,000 When I bought the truck it was a theft recovery vehicle where the turbo, injectors, FICM and wiring harness were stolen. The company I bought it from replaced the injectors, wiring harness-new, and a used FICM, and turbo. Also has EGR delete and SCT tuner with basic tunes. I believe the SCT was put on to mask another problem. No dealer would spend that kind of money to sell a truck unless something was wrong. The truck would accelerate some with the tuner but shift the tires so hard it would bark them. I removed the tuner and went back to stock program.
The truck will barely move and takes a long time to accelerate under a load. In park and neutral it is fine. A friend has a ford diagnostic program on his computer and says the readings were all good except EBP was a little high. Removed exhaust and air intake to verify no restrictions. Turbo sounded like the vanes might be sticking so I replaced the turbo and VGT solenoid. Now truck feels like its trying to make more boost but not transferring power to the engine. Have blown the silicone hose off twice now during testing. Checked the EBP sensor and tube and only thing I see is a little carbon buildup inside the sensor. What else to check. I'm new when it comes to diesels.

I have a 2012 F350 I keep the hubs in auto all the time. In the winter I just flip the switch to 4 high when I hit snow conditions. I know to shift in or out I need to be below 55mph. How fast can I safely drive in 4 high on the interstate? I drive hundreds of miles at a time in the winter. Some times if the roads clear I will cruise at 70-80mph. This is a question of mechanical safety on truck components not driving safety.

Well, since I replaced the MAP hose a few weeks ago the old girl has been running fine. Until yesterday. I was leaving work and she had low boost, less than 10PSI, and as I passed by a parked tractor trailer I could hear the sound of high pressure air escaping because I had my window rolled down.
So today I checked it out. I found three possible leaks spots, BUT no "smoking gun". Take a look at the pics. The damage you are seeing is on the outside of the hot side boot at the turbo and the bottom of the cold side CAC tube. The cracks don't appear to penetrate to the inside. Could these still be possible leak sites? IDK.
I'm going to order replacements anyway. Ford wants WAY to much for these parts. I checked the MAP hose and it is just like new from several weeks ago. Also, I inspected the inter-cooler as best that I can without removing it. I don't see any issues with the tanks or the tank-to-core mounting. It all looks normal. If it does fail where does it normally fail at?

2013 CCLB, 33,500 miles, stock emissions
While towing a 9000 pound trailer at interstate speeds (75 to 80 in Wyoming), when pulling a hill, the truck downshifts to 4th gear, boost is about 18psi, eng and transmission temps in the 230F range, EGTs around 500C or 935F. RPM increases normally to 3000 then the turbo gets very loud and boost drops to about 10psi. The truck shifts to 5th gear, noise decreases but is still present, shifts to 6th and noise goes to normal after a couple seconds and boost builds normally.
This just started today. I have about 8000 miles towing this trailer and never had this before. I have about 350 miles until I'm home so I'm headed back out. Will play around with manual mode and see what it does. I also took a video of the gauges while this happens. Audio is difficult to discern. I will try to get better audio and post when I get home.

I've been having issue with my truck lacking boost over the past month or so. The psi levels are normal in the morning when I start it up cold, the problem almost always occurs at start-up when the truck is somewhat warm and has been sitting for an hour or more after use. I've had boost levels at idle from -0.14psi to -0.56psi and as low as -1.2psi when driving as the problem is occurring, but it eventually kicks on and goes to normal levels after several minutes of driving. After originally taking the truck to a local diesel mechanic I was told it had EGR codes and they recommended installing an SCT tuner and cleaning the EGR valve to solve the problem. I had them install an SCT 5015 tuner and clean the valve but I've still been having the problems with boost.

I have a 1999 Explorer. 5.0 V8 auto AWD. Motor bogs down when going up hill. Smoke coming from under vehicle. Recently tuned up & oil change. 157,000 miles. No warning lights. Not over heating. No burnt smell from oil or trans fluid. No leaks from motor or trans. Oil & trans fluid look clean. I have a little mechanical knowledge. Someone said it could possibly be a bad catalytic converter.

Just bought my 2013 Platinum 350 DRW 2 weeks ago. 9,000 miles on it. I was cruising along yesterday at around 45 mph in 6th gear going up a slight incline. Truck was fairly low rpm don't remember what exactly. As I'm going up this hill it begins to shudder quite a bit almost seemed like the turbo shuddering while lugging up the hill at a low rpm in 6th. I stepped into the throttle to get it to downshift into 5th and it stopped. I never experienced anything remotely like this in my 2011 6.7.

2011 ford f350, 200,000 miles. I was getting an antifreeze spray on the windshield while pulling and going up a hill. It was from exhaust pressure going into the coolant system. It was building over 16 psi and blowing out the degas bottle.

a few times when making a tight turn on hilly terrain or a hill on a road, I've noticed a grinding sound in the front of the truck and a vibration in the steering wheel. I've so far chalked this up to the hill assist feature, but today I was on relatively flat ground in a parking lot with a dip in it. While crossing the dip in a tight turn, I noticed the same thing again.
I've checked the tires/wheel wells and there is no rubbing, etc.

In addition to significantly louder noise from the Turbo on start-up, we've started to hear a pretty concerning noise while descending a hill in Tow-Haul. Not sure that the T/H has anything to do with it other than getting the engine in a RPM range that causes the noise. We've taken it in and tech says "That's just normal noise"... What ever that is.
Here is a link to an example : Tow haul making a lot of noise in my F350 diesel. Pulling a very heavy horse trailer. - YouTube

Today I visited a buddy who lives on a pretty steep hill. I always set my E-brake while in Neutral to make sure it's holding the truck before sliding it into park. So I got out and unloaded a few things and was in his garage. I heard a skidding sound outside, I was about 40 feet away from it when I looked out my truck was skidding down the hill!
I ran out and to the drivers door, opened it and pressed on the brakes with left hand right when it hit the bottom of the hill and it barely stopped from hitting the blue car parked on bottom of the hill. Next time if I stop on this hill I'll make sure it''s nose up hill and make sure I have 4X4 engaged to have all wheels locked up. I know this probably happened because the lack of weight on the rear wheels but this was a pretty crazy scare with only 7800 miles on her!
You can see the skid marks from my rear wheels, my friend lives in the middle of the block.
