Ford 6.0L Power Stroke Diesel :: Truck Is Starting To Surge A Bit Like ICP Sensor Going Bad
Jul 25, 2015
I started having an issue with a rough idle soon after startup about a month ago. I thought it might have been stiction so I added some Archoil stuff the other day to my oil interval change and although I have not put too many miles on it, the rough idle is still there.
At startup the engine runs great. I did notice a few times a little longer than normal crank (~3 seconds) where other times it fires up in less than 1 second. This has happened twice in the last month. Once the engine runs for about a minute I get an uneven idle......I wouldnt necessarily call it a miss per say. I took some readings for the ICP and IPR and can provide them if someone needs them. Once the truck warms up it seems to idle better but still not 100%. I have no power loss, no hesitations jut a weird idle with intermittent surging while in gear.
The truck is starting to surge a bit like an ICP sensor going bad but not as pronounced as the last time this happened to me 4 years ago. Basically trying to get opinions as to what it might be or what to check next. I am leaning toward one of three things.....stiction, ICP or IPR valve (original). FICM voltage is good but my fuel pressure gauge broke, but the blue spring upgrade I did.

Experienced a weird transmission issue this weekend. Started truck up first thing in the morning, only a short warm up, it was about 50*F. Drove about 200 yards to the gate. Stopped with foot on brake while wife got out to open gate.
Felt truck lunge/surge a little. Thought that was weird. Then it did at again, but more like a double surge, jumping in and out of gear.
Rolled forward through gate then stopped again with foot on brake. It did it again. But this time I noticed the gear indicator in the dash jump. It was shifting from 1st, to 5th, down to 3rd, then back to 1st.
I pulled out my phone and was able to catch video of it doing it a few more times. Start about 16 seconds into video. Transmission Ghosts?
About 1:20 in I drive forward and it shifts to 2nd fine. I stop again at 2:00 in.... and it does it again around 2:30. Then it also flashed a "Check brake system" and "Service AdvanceTrac" message for half a second (around 2:44 in video).
After catching video, I drove the remaining 1/2 mile driveway to the county road and stopped again. It didn't do it any more. It did however flash a traction control off/on message for about half a second. Didn't catch that on video though.
Drove 12 miles to town to Ford dealer. Service Dept was closed (Saturday). It didn't do the shifting again for the rest of the weekend. Made the drive home Monday (140 miles) without a problem.
Dropping it off tomorrow morning at 7AM so they can try to fix it. They hope it stored some codes even though it never gave me a wrench light or other trouble light that stayed on. Hopefully it's a just a software glitch or a faulty sensor.

2004 6.0 Diesel. First the truck would die after starting, then start up again after a minute. Then the truck wouldn't start at all.
Trouble codes indicated low voltage on all injectors leading me to conclude a dead FICM. Replaced the power module in the FICM and reinstalled, but still no start.
48V at driver's side screw under the cover. 12V at the next screw, the next appears to be ground. The passenger side screw is 0V. One post indicated that should also be 48V - is the true?
I probed the power coming in - logic fuse is good. 50A fuse in the cab is good. Relay seems good.
The Ford FICM diagnostic indicates 12V power should be coming in on FICM connector X3 on pins 7, 8, 4, 23, 24, 25. I have 12V only on pins 7, 9, and 27. When I pull the relay I lose power on pin 27.

Parked the truck last night and all was fine. Went to start the truck today and let it warm up before hooking up the trailer and it dies withing a minute. Go to start it again and nothing. End up killing batteries. Checked for codes and had a bogus EGR code P0404. Bogus because the tune I run doesn't have the EGR enabled and it is deleted. Still plugged in though.
Hooked up dual battery chargers and sent the boy to pick up fuel and oil filters and oil. It was over due in both areas. Changed both and still no love. So I drag out the laptop and set up my AE to monitor FLP, FLM, IPR, ICP, ICV, Sync.
KOEO
FLP 11.00
FLM 47.0
ICP 0
ICV .24
IPR 14.25 odd right?
Synch 0
Cranking
FLP 9.6
FLM 47.0
ICP 800-1600 varied the longer I cranked
ICV 2.2
IPR 14.24
Synch 1
still no start.
Still no codes.
I then cycled the IPR through AE a few times and turned the key. Damn thing fired right up.
Idling
FLP 11.0
FLM 47.0
ICP 875
ICV 1.4ish
IPR 26.4
Synch 1
I pushed the RPMs up to 2500
FLP 11.0
FLM 47.0
ICP 2200 iirc
ICV 2.24
IPR 42.0ish
Synch 1
Turned the truck off and restarted it a few times. No issues. Turned it off and pulled the positive cables and put the chargers back on it.
So the question is .....Is the IPR sticking on me? I just replaced the HPOP in the spring along with the up pipes. Made sure everything was clean. I actuated the IPR and cleaned it out. Put a new screen on it had zero leaks.

Oil temp sensor - when I turn the truck on - it goes right to half way. I am guessing it is broken ? But then again, if it was broken, why would it go half way ?

I have a 04 6.0 and lost with it. I parked it the other night and in the morning I went to start it and it acts like it's only running on half the cylinders. I haven't had any issues till now so I replaced fuel filters and air cleaner is fresh but no change. It is not throwing a check engine light it isn't smoking excessively. I don't know where to check next.

The other day, I started having problems with the truck not starting when at operating temp. Went for a drive and stopped a a scenic overlook, and spent about 30 minutes taking pictures. Went back to the truck, and it wouldn't start. Outside temp was about 95 degrees.
I tried for about half an hour to start it, but all it would do is turn over. There was a work crew there with their heavy machinery, and I was able to borrow their starting fluid. One quick squirt into the intake, and it fired right up.
Although I do have an oil leak from the right valve cover, when I checked the oil, it was just off the full mark. The truck was parked on a slight angle with the driver side being about a foot higher than the passenger side.

I Have A 2013 F250 I Have A H&S On It. I Have It Delete. And The Cel Comes On In The Morning, Ill Get The Code In The Morning. But It Has Something To Do With Coolant Temp Sensor. It Also Does Like A Bucking/Power Surge. Boost Goes From 0-10-15 ,When you Hold Pedal Steady. Do I Need To Update My H&S Or What?

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?

I've been getting a surge or revs when getting up to cruising speed before it drops into overdrive or or a constant speed. Happens around 1800-2200 rpm before up shifting to the next gear. More noticeable if under a load or going up a grade when it will hold gear longer before shifting. Only thing I can think of that would be related is the truck does lack some power on a cold start for the first couple miles before getting up to temp. I've cleaned the ebp sensor and it appears to be working correctly, reading within .1-.2 of BAR/MAP key one engine off. VGT solenoid is clean but have no real way to tell if it's working correctly. Other values icp/ipr temps fluid levels appear to be correct. Just changed the oil and it continues, changed the transmission oil and filter about 3000 miles ago. I've had this going on for about 1000. Started about the same time I changed tunes to PHP. They haven't been able to find anything in the tuning yet that could be causing this or if it is just making it show up now.

My 2003 6.0 has started to surge at idle after driving for awhile. Like when I drive to work (30 min) and pull off the interstate the idle will bounce around at the stop sign (only jumping like ~100rpm). Does this sound like the ICP to you? I've replaced it once before and am wondering if it's time to do it again?
Also the truck will sometime be hard to start. And when I say hard to start I mean turn the key, let the GP cycle the turn to start and it just cranks. But as soon as I turn the key back off and cycle the plugs again it'll fire right up. It doesn't seem to matter if it's hot or cold. It's been doing it since I got the truck. It seemed to get better after the 1st ICP but didn't completely get fixed.

I've got a slight surge that's very noticeable cold and not so much after warmed, I can hear the turbo surging and feel a slight power increase on and off, checked with forscan the normal values, alls inline, I did not ck fuel pressure yet but will, I noticed vgt, boost fluctuates when this happens, icp ipr readings inline, this is a 04 with throttle plate inside the air elbow area, can this cause a surge and how to test this, I am not familiar with this setup as my 05 does not have it.

I have a 2007 6.0 crew cab that I'm having some recent issues with. When starting cold in the A.M. the truck will crank, start for a half second then shut down, after about 3 times it will finally catch and keep running. I'll let it warm a bit, then for the first few minutes of driving it will have a pretty noticeable surge on acceleration only, not at idle.
The surge goes away mostly after warm however you can still feel it happening between 22-2700 rpm and can just see the rpm moving back and forth a little. Lastly the fuel mileage has dropped a good amount. If I baby it around town I'll get 10.5 and can see 9ish occasionally.
Truck has brand new ford fuel filters, ford blue spring, fresh oil change, FICM has 3k miles on it, new batteries in last 6 months. Turbo egr oil cooler done in last 20k. Currently has 120k on it.

So my buddy was driving my truck and boat through Amarillo and suddeny had a buck/surge accompanied with black smoke. I left my torque app with him. Its throwing codes: P2287,2285, and P????(fault log got erased and I'm going from memory) concerning #8 cyl. I got there today and we noticed coolant leak on left side. Its small and I cant tell the source, but it is wetting the exhaust manifold on left side. Also now its blowing white, black, grey smoke. At idle its more white/ grey. Under load it mixes a little blck in. I only had time to check the ICP on torque and at idle its bouncing from 0.9 to 1.1. Unplugged ICP ran about the same. Still started and idled fine with white smoke. No oil in ICP or connector.
So I'm no expert but I think ive got a bad icp and something else going on. I didn't pull the egr valve and look so no idea on the cooler ,yup syill have the cooler. Degas has a small amount of white residue directly under the cap but no puking. Degas is just below the max line (on the sticker).
One other note only code originally was the 2287 last night. Now this am there was the other codes ref'd above.

The service truck threw a CEL, and i pulled oxygen sensor performance bank one sensor one code. That would be driver side sensor between the manifold and cat, rite? Don't want to change the wrong one...

I want test my fuel pressure. What is a good gauge or kit to buy? My truck has lost power towing and is now starting to miss a little. I'm wandering if i my problem is in the tank. Is there a good scan tool that would diagnose things too?

I had issues with my F250 cranking last winter when the temperature dropped, so I changed out the glow plugs in the spring. I hadn't been able to truly test them yet, since it hasn't been cold, but the other morning my truck wouldn't crank up. It was 40 degrees out the night before, and it had been almost 24 hours since I cranked the truck, but it seems to me like the truck shouldn't have an issue in that mild weather.
I'm not sure what I need to do next to try and fix this problem, it's been driving me crazy and risks stranding me if I park for a while in an area where I am unable to plug by block heater in. The truck cranks fine when I have had it plugged in for a while, so I'm fairly certain it's a heating issue. I haven't done any tests since last year, but I know that the GPR was working properly last winter, which is why I changed out the glow plugs.

I have a 2000 F450 with a 7.3. I am having problems starting it. Batteries are good, engine turns over strong. It has started a few times after a extremely long crank (so long I am sure I am burning out the starter). I have replaced the CPS since it was cheap enough but that didn't make a difference. I have unplugged the ICP and it is very oily inside the connection. Does this mean the ICP should definitely be replaced? The truck will not start with the ICP unplugged. Should it be able to start with the ICP unplugged? Other items I plan on looking at at the IPR and possible the IDM box. Am I on the right track?

What the sensor is for? In the course of removing the rough country bumper from my truck and installing the 2005-2007 factory front end I found this guy hanging out with wires cut. I haven't attempted to wire it back up because I want to know what it is first. It would appear that the sensor is suppose to be screwed in to something.
