Ford 6.7L Power Stroke Diesel :: Turbo Surging When Running In Cruise Only At 55 - 60 MPH
I was wondering about same turbo problems that I'm having? When running in cruze only at 55-60mph the turbo will surge from 2-12 psi up and down repeatedly. It sometimes will level out for a couple seconds and then continues to do it. I had it to the dealer and the service manager drove it and said it seems like it's searching for something, but since there was nothing from ford about it he couldn't do anything about it. There was an update for a prior serial number but my truck has the current software. What kind of damage is this going to do. It sucks because alot of my driving is at this speed.

I had a nice level straight stretch in front of me and engaged the cruise control. No go! I tried a few more times and it still did not engage, even with various button sequences. My thought was that this truck is a computer on wheels. So at the next opportunity I stopped and shutdown the engine, turned the ignition switch OFF and then restarted started the engine (and rebooted the computer). The cruise control works fine!

My cruise control stopped working today on my trip back from Yosemite. Tried looking through the owners manual, but apparently it doesnt have its own fuse. Everything else seems to work just fine, so I am gonna start there.

I have been trying to figure my cruise control not working. I verified the switch for the brake pedal and the one on the master cylinder are not the problem. I have read about the clock spring but would like to verify signal is passing through/ not before replacing.
2 Questions.
#1 I have is how does the overall system work? Ok not that in depth but, is there some kind of servo that regulates the flow to,the injectors or is it strictly controlled by the PCM? and it tell the injectors to open to allow fuel to pass.
#2 Looking for a wiring diagram for the cruise control control circuit. Namely looking to verify switches are working.
Ford - Freestyle :: 2005 - Surging And Hesitation While In Cruise Control At 70 Mph
I have a 2005 Ford Freestyle with 59,xxx miles. My wife and I drive it less than 7,000 miles p/year. About six months ago it began to surge (we had already taken it back to the dealer for some work on a recall related to surges while idling). However, the surge that now occurs is not related to the recall--it can happen anytime, even when on the highway while in cruise control at 70 mph. It makes the driveability of the car questionable. We have had it back to the Ford deal repeatedly, only to be told a number of high dollar things that seem to be based on guesses rather than actual data. No codes have come up with computer diagnostics.
We have also taken to independent mechanics, only to be told there is nothing wrong. Only once did a mechanic say that he 'felt' the surging when he test drove the vehicle. But even then, the shop said that they would have to do a tune-up (which raised a red flag with me because tune-ups no longer seem to be the proper term to be used with modern engine maintenance). I did a lot of research and as a result I asked a mechanic to test the fuel pump. The result is that the low pressure was 39.5 lbs, and, the high pressure was also 39.5 lbs.
Ford Super Duty (1999-2016) :: Surging When Doing Silent Downhill Using Cruise Control
My 2001 F250 with 5.4 gasser surges when it rolls downhill when using the cruise control. It does not do that when it is going up hill or on flat level highway. Why it does that? This is only when I use cruise control.

I was driving my 2011 the other day home from work and experienced a rough idle. Normally the truck idles pretty smooth. I noticed when I was driving at highway speeds the truck seems to shake a lot. I pulled over and turned the truck off. I did a walk around and could find anything out of the ordinary. I started it back up and no more rough idle. However while i was driving at freeway speeds I could feel a momentary lack of power, then the truck would regain its speed. This would only last a sec or two.
I figured I'd give it a few days.... well now its gotten worse. Its doing the same thing but a noticeable difference in the lack of power. I still have boost pressure and the turbo seems to working fine. Im trying to figure out what it might be. I'll be taking my truck into ford again...
Ford 6.0L Power Stroke Diesel :: Surging When Leaving Red Light
Just replace the b solenoid in my transmission last night; everything running good now, but for some reason it started doing this weird thing where if I come to a complete stop at a red light, then ease into the throttle, it will start surging,bucking. If I give it a little more gas on the pedal it will smooth out though. It only does it if u ease into the throttle after a complete or near complete stop. What's going on?
View 7 RepliesFord 6.0L Power Stroke Diesel :: Light Surging While Under Acceleration
I'm getting some light surging while under acceleration. None at idle or once in overdrive. I cleaned out by exhaust back pressure although it wasn't really that dirty. Thinking about replacing the sensor anyway but it is a little pricy to just buy for no reason. Should I look for anything else? And where I'd the best place to get one? I've seen the 20 amazon ones or over 100 at the parts store.

I replaced the exhaust back pressure sensor and the readings on my sct programmer didn't change at all so I don't want to keep blindly throwing money at it if one of you has experienced this and found a cure. The interesting thing is it never throws a code or check engine light or anything according to my sct. Doesn't even show that the egr valve is unplugged. I have read that it could be a bad turbo, vgt solenoid, icp, throttle positioning sensor, or a couple other things.
It feels like I'm the front car in a bump draft in cup racing when I'm at a steady speed. The truck has arp head studs, new style egr cooler with the tubes, coolant filtration, new oil cooler, new ficm, blue spring, all filters have been changed in the last month.

View 11 RepliesFord 6.0L Power Stroke Diesel :: 2006 F250 Started Surging At Idle
Just bought a 2006 F250 with 6.0. A week or so ago, it surged once at idle at a light. Sort of felt like someone bumped into your rear. It has gotten more frequent over the last week or so. Now it does it often. It tends to rev up and then back down again over and over. Then it will clear up again. My brother said his 7.3 used to have a similar problem (as did quite a few others apprently) and it was the Cam positioning sensor (CPS). Where is it located?
View 14 RepliesFord 6.0L Power Stroke Diesel :: 2005 - Engine Started Surging - EGR Delete
A few weeks ago I got in my 2005 EX and started for work. As I idled in traffic, the engine started surging (it had never done this before). So I took it right to Ford and dropped it off before it got worse. Of course, they couldnt look at it until Monday (this was a Thursday), so I had to get a rental.
I get the call on Monday that the surging problem was an injector, but covered by my warranty. But, it seems that my EGR cooler was bad, but even more important was my blown head gasket.
WHAT?! My truck did NOT have a blown head gasket when I dropped it off. But thats besides the point. There was much back and forth between Ford and my warranty company, but finally I got them to cover the head gasket.
But, I had to pay for the EGR cooler. So I asked the Ford mechanic if I could supply him with an upgraded cooler, so I wouldn't have this issue in the future. He said no problem. I then told him I was going to buy a Bulletproof and he said no, get a delete kit. He said "I've done a number of these, and its really the best solution.". He even HEAVILY recommended the ADT Delete kit. He even said that since I have a 2005, we can just leave the EGR valve hooked up and I wouldn't have a CEL issue.
Fast forward several days. I picked up my EX last night and... CEL is on. I called and spoke to the mechanic and he told me that I must have an upgraded program, and that my only option is a tuner to turn off the EGR completely. He also told me that I don't need an expensive SCT or Bullydog just for the EGR.
Anyways, with all of the above setting of the stage complete, just wondering what my best option is here... Is there a simple/cheaper tuner I can use to just disable the EGR? Is it worth the money to get a more expensive tuner? For the most part, this is my daily driver and I don't need a performance or towing tune. I wouldn't mind better mileage, though
Ford 6.0L Power Stroke Diesel :: Surging Idle After Long Highway Trips?
A few weeks ago i had a surging idle issue very intermittently, and it went away for a while so i stopped thinking about it. Just got back from a weekend in vermont, about 130 miles each way, and i noticed as soon as i got to vermont and came to a stop sign it was surging, and when i just got home it was surging again. Why would this have picked back up after long stretches of running for a while? Runs great as far as i know, just have this surging idle for some reason.
View 14 RepliesFord 6.0L Power Stroke Diesel :: Fluctuating Idle / Surging And Stalling - ICP Bad But Not Leaking?
So any ICP sensor been proven bad but i was not leaking oil? The symptoms of my truck sound similar to a bad ICP...fluctuating idle, surging, stalling, but it does run and start. IT tends to start acting up when it hits operating temp.
I have an 04 and the ICP sensor is in the easy spot to get to on the valve cover vs under the turbo (that's awesome) so its an easy swap. but just wondering if there is any way to test it over simply swapping it. I do not have a monitor yet but a dongle is on order and will get the torque app for my tablet.
Ford 6.0L Power Stroke Diesel :: 2004 - Surging On Takeoff And Blowing Black Smoke
Ok I have a 2004 f250 6.0L, has 104k on it. A little back story... truck was running well when I started to get surging on takeoff and it was blowing black smoke when it surged. After it hit 1600 rpm it would blow out and run normal. So did some research and found it could be the FCIM, I have the 4 pin and tested it and had 48.5v so it tested good. Did some more research and found symptoms leading towards the ICP so I replaced that and the ICR also.
Upon doing this my surging issue cleared up but now I'm getting a miss around 1200 + rpm weather it's in park Reving it or driving, but it is not throwing any codes, I did check with my code reader. I have also changed both fuel filters and have the EBP sensor on order as I hear they can be troublesome. My question is what should I do next or look at? I was trying to avoid the dealer so I can learn more about the truck in diagnosis.
Ford 6.0L Power Stroke Diesel :: Subtle Engine Sound Changes While Driving At Highway Speeds - Surging
I've been noticing some weird, very subtle engine sound changes while driving at highway speeds lately. Something almost like surging, but not. I don't know how to describe it. I might try to make an audio recording next time I take it out so I can explain it.
Anyway, I don't know why but ICP popped into my head. Maybe, for some reason, the engine was varying ICP causing the surging sounds.
So I hooked up AE and did a test. I've attached a screen shot.
With my idle speed actuated as high as it will go, and ICP actuated as high as it can go, I can only get a pressure of about 1450 PSI. I always thought ICP should go higher than that. I seem to recall reading somewhere around 3600 PSI.
So am I misinformed, am I reading the data wrong or do I have a problem? How high should Injector Control Pressure go? I missed it in the screen shot, but ICP is actuated to 100%.
