Ford 6.0L Power Stroke Diesel :: Powerless And Rough Idle Until Reaches To Running Temp
Feb 10, 2016
I have a 05 6.0l. Egr deleted. And my truck has a rough idle and power loss. Ive tested the ipr and the icp and they are reading at specs. I've also replaced the Hpop about 1500 miles ago. It has a real rough idle until it's at running temp. And it has power loss, I'll be driving down road and theres no where near has much power has there should be. And the idle will jump between 1500 rpm and 2000rpm.

My F250 Will not start once the oil temp reaches about 117 degrees. Once oil temp drops it fires up. In the morning it only crranks for a couple of seconds. What could this be? I am getting over 1300 PSI HPOP while cranking. FICM Volts 48.5. Just no hot start. What do you think it is and how much at the repair shop. I have the Torque App, IPR values are good to I think.

I have 2007 6.0, rough idle starts, rough and no power till engine reaches running temperature, runs great after that. If the engine is off for half hour, and restarted, runs rough again till engine temp is back again.

In your experience, what issues have you seen that caused intermittent rough running at idle, but did not throw a code. I have monitored (with numerous scanners/gauges) this 6.0, but cannot get a code or see any of the sensors out of spec.
At Hot idle:
IPR: 24.2
ICP: 640
ICV: 0.90
MAP: 14.7
MAF Volts: 1.5
EOT/ECT Deltas within 10 and Avg ECT=192, EOT=199
EGR Valve cleaned and EGR demanded = EGR Measured
Vehicle will run rough after long runs or towing. Cylinder Balance test showed all injectors on. What could be the cause?

I have a 2006 f250 with a 6.0 with sct livewire, arp studs&gaskets, oil cooler, blue spring mod, sinister egr cooler and it had been giving me some real troubles lately. Started off as a code for injector #8 so I replaced that and while I was in there I rebuilt the oil rail with new nipple cups and orings, replaced standpipe and dummy plug in that bay(also updated the arc fitting less than a year ago), new exhaust back pressure sensor tube because it was right plugged with carbon, and a new egr valve because that was right packed with carbon as well, all backed together and torqued to spec from the Haynes manual and the truck still sounds like its missing at an idle with some light smoke(just smells like unburnt fuel). From there I went to test the ficm which is also only a couple years old and it seems to stay at a constant 48v so at this point...

So my truck is intermittently running rough at idle for the most part and sometimes slightly loses a little power while driving down the roads. Seems to run worse as it warms up. When it runs rough it sounds like a cylinder is missing. The truck is throwing code P0269 for Cylinder 3 Contribution/Balance. Smoking isn't horrible coming out of exhaust but it's there and it comes out at a constant rate. The injector has been replaced by the previous owner recently. It has an egr delete, new turbo, ficm, ficm harness, HPOP, and stand pipes.
When I put the starter solenoid wire to the battery you can hear the engine skip. I did a compression test on cylinder 3, put oil in the cylinder and did the test again to find that I still didn't have compression. Assuming that this was an issue in the head I had my doubts that it was a bent valve and it could have been a bent pushrod.
Sure enough I found the intake pushrod for cylinder 3 was bent slightly so I replaced the pushrod. I started the truck again and seemed fine at first but just like before it started to run worse as it warmed up.
I was able to drive it to the gas station real quick to fill it up on fuel and drove back home which is a short drive, but the truck was running worse and worse and it eventually died on me. I attempted to start and had to jump start from my other truck and the 6.0 would not start. I ended up frying the starter trying to start it so I'm taking a break from it for now.... Ended up pushing the truck home.
The only thing I can figure is that I don't have oil pressure in the oil rail which is why it died but I don't understand why the truck still ran rough and pulled up with the same P0269 code....

So the other day while towing my 5er my temp alarm on my CTS went off at 220. I let off and it cooled down, but not where it usually runs. Unloaded it will run at 200 where it usually runs at 180 or less. Its an 06 EGR deleted, coolant filter, studs, the works. Water pump? Thermostat? Coolant level is ok.

I recently noticed on my truck that my oil temp was running high, I would go down the interstate at 75 mph and the oil temp would get up to 215-218 while my coolant temp would sit around 192-196. So, I took it into the shop and was told it was most likely a bad oil cooler and had it replaced 2 years ago when I had my injectors and gaskets replaced along with my egr deleted. So, got the truck yesterday, going 60mph down the highway, truck ran an oil temp of 192 and the coolant at 188. Was great, but later on once I got to the interstate going my 75 mph, The oil temp jumped to 209 and my coolant sat at 192. Not sure what the deal is, was told the oil cooler was replaced and wanted some input on what else I could be looking at. I currently have 5w40 synthetic oil running in it. I have an EDGE CTS tuner on it and tuned it back to stock mode, but oil temp still jumps up to 209 and coolant remains around 190-192.

While driving home last night my truck started to overheat, the temp jumped from where its been running at lately (around 210) to 240, I stopped and took it easy getting home. This morning I sprayed down the radiator to clean out any mud that may have gotten in it from field work at the office (its always going through some pretty deep stuff). It ran fine for about an hour then it started to over heat again, I got it home and did a complete radiator flush and then did a test drive. It still overheated so I decided to try something, I released the pressure in the system by unscrewing the cap partially and drove it around again, this time it didn't overheat, put the cap back on and the temp jumped right back up to 240.

Well, I've read a lot of threads on this problem! Try to do my own repairs, so I'm learning and not spending a lot of cash at repair shops.I have an 04 6.0 Super Duty Crew. Starting running rough on way home. Pulled over ,then it died.wouldn't start. Had towed home. Replaced ficm circuit board. No start. Replaced Harness,
icp...... ipr Sensors. Still no start. I noticed there is another circuit board inside ficm. Should I have bought the whole ficm unit?

I am having a problem with a 6.7. The truck has 9900 miles on it. It has a dpf delete, egr delete, Spartan tuner and a snow stage 3 kit. The truck lopes at idle but once throttle is applied it levels out but still runs a little rough. Its keeps saying its in reduce engine power no matter how many times I clear the code. If I clear the code it will come back in 2 seconds with out cranking the truck or anything. Rail pressure is telling me 31090 psi and not changing running or not. I have changed rail pressure sensor, and pressure control valve with no result. The green and violet 5 volt reference that feeds those sensors is only putting out 1.2 volts. Put a new pcm in it still the same and now has quit running totally. The codes are P0193, P0335,and P06A6.

I got a 2005 f350 6.0 deleted and studded with air dog 2 4g pump, 125k miles. It started running rough then just died all within a few miles tuner showed code for injector 6 and ficm towed into ford dealer didnt have time to mess with it. They said ficm was bad had them replaced it then they said i need whole new fuel system lines,harness,pump,sending unit ,tank the whole 9 yrds. Which i thought was uncalled for so i called up airdog which system i had on there and they laughed and said ford garage is full of bs that they will upgrade my pump to the 4g and new harness.
So I took that stuff to garage had them swap it out and now they said come get the truck they wont work on it anymore that now it needs 3 injectors and they wont touch it with aftermarket fuel system on it. So I go to drive it home and it starts but runs rough and u can hold it to the floor and it wont budge bearly idles up and builds no boost my tuner is showing injector 2,3,4 now which wasn't a problem before i took it into the garage. So im not sure what happened to cause this all to happen but before i sink any more money into it is the 3 injectors enough cause to make it not build boost now .

Did my oil change last night and filter swapped both fuel filters on my 04 f350 started it up last night drove it a little bit and she was fine. Went to start her up this morning and she was pissy so I drove her a bit once warm and she feels like there is a dead cylinder maybe??

I was towing a trailer about 600 miles truck was running great, pulled in for fuel and truck was running rough, refueled and was on my way then when going down a hill (Idle) it just quit, had to tow remaining 200 miles.
After reading the forums I replaced the ICR (ICR screen was damaged) Truck now starts but its very loud and missing like crazy. and surges if i give it a little gas. codes 0268, 0281, 2284, 2288 I also replaced the ICP.
should I replace the injectors? what causes this?

My Excursion got 4 new injectors a couple weeks ago and when I got it back, it was running rough. My mechanic told me it was going to take about 100 miles for them to break in.
300 miles later and it is still running rough. So I opened the hood, took a look around and saw this wiring harness unplugged. Where it goes? Youtube video shows where the harness is [URL] ......
Also, my truck has been shaking violently at 50 miles per hour, unless I hit tow haul, then it is moved up to 60... I am assuming its connected some how to that wiring harness being disconnected.

Wife just pulled in said your trucks running rough. Right out the gate went out Checked ICPV its at 0 KOEO... Noticed a CEL P2285...
ICPV seams to be Jumping all around at Idle...
it stutters and smooth's out some I believe its going into default mode...
its acting different then last time the ICP went south thinking a wire is shorted or that's my guess ...
is it just me or do Vehicles seem to break down more when its Cold...

Truck is running bad when first cranked in the morning, is bucking and running rough until warmed up, think the oil needs to be changed and which additive is better the archoil or Rev x?

My truck was running rough when cold, I went to check the ficm voltage while wife was cranking and coolant shot right into the ficm and cooked the sumbitch. Stop laughing that stuff happens to me all the time. Anyhow, got a new ficm and truck wont start. Starter kicks out after a few revs. I ran my own solenoid wire to the starter and it cranks just fine. ficm at 48.5 koeo and cranking, icp 1100+, ipr from 14.8 to around 40%, ...
It takes a few seconds for the cam/crank to sync but it does. I changed the fuel filters and primed it, Got new batteries, and threw a crank sensor for s+g. With the key on and me cranking it using the solenoid wire, it almost starts. But from the key it will kick out after a few seconds. All fuses and relays are good. I hear the pcm also controls the starter, could that have cooked when the ficm went or would it blow a fuse? Diagnosing using a scangauge2 ....

I have a code for iat sensor 1 circuit high. It's the only code I can pull. I replaced the sensor in the manifold and still no change. The truck revs up when started but kinda finds its idle rpm after a second and the idle fluctuates some when the truck is warmed up too. I have a snap on solus and all parameters seem to be good. Icp sensor is also new thinking it might be the cause. Other than that the truck runs perfect and doesn't miss a beat.

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 towed my 32 ft/ 600lb travel trailer 115 miles into arkansas today. When I arrived at the campground, the engine was running rough and shaking the vehicle. I saw highs of 175 (trans temp) 1150 (EGT), 214 (ECT), and 224 (EOT).
I recently installed the canned trans tune from my new SCT X4.
I pulled codes (none), checked cylinder misfire count on scangauge 2 (none). In fact, all gauges on the SG2 were within spec. I popped the hood and let it idle for 15 mins. Temps all dropped down to what I usually see after normal driving (not towing).
The engine did start to calm down as it cooled, but still sounded a rough
