Ford 6.0L Power Stroke Diesel :: Rough On Cold Startup - Surge / Lack Of Power During Light Acceleration

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?

Ford 6.0L Power Stroke Diesel :: Bucking And Missing Every 10 Seconds Or So

Truck is bucking and missing every 10 seconds or so and will stall when taking off in drive sometimes but fires right back up? I got a lot of codes in the torque pro app but some are in grey. Not sure what that means. EGR has been deleted so that's why I got those codes. I was cleaning the back of the truck the other day and found a can of quick start . Guess that might be why i got codes for glow plugs also. I'm gonna post up pic of my codes and numbers of truck running at idle in drive. So far I see I got a code for cylinder 6 contribution? It's in grey tho whatever that means.

Ford 6.0L Power Stroke Diesel :: Transmission Bucking When Shift From OD Down - A/C Turning Off And On

We are on vacation pulling the 5th wheel. On the last of the three days driving the transmission starting doing something I have never seen. When running about 60mph and starting up a grade, when I push the pedal and it should shift from OD down, it bucks really bad. It only does it under those conditions and only when towing. It does it when the tow/haul is on and tow haul is off. Also, in the afternoons on the last two da,ys the A/C has started to turn off. The fan still runs but the cooling cycles off. After a while it comes back and is ice cold but then cycles off again. It only seems to do this when the engine fan is running to cool off the engine under load. I have it scheduled at the local dealer for a transmission service and A/C check....

Ford 6.0L Power Stroke Diesel :: Intermittent Bucking / Hesitation Up Hills - No EGR

When I am on the highway, my 2005 Excursion (6.0) will hesitate/sputter/buck intermittently, usually between 70-80mph/ 1800-2200 RPM, but especially triggered by hills and inclines. Each sputtering episode usually lasts about 5-10 seconds and then will go away for minutes at a time. Does not sputter upon take off or initial acceleration. There is no smoke of any kind. Just got it out of the shop where the mechanic replaced ALL 8 injectors and the fuel pump, as well as flushed the fuel lines, and new fuel filters, and oil change (2 injectors were bad, but there was metal in the fuel filters, so to be safe I replaced all of them - ALL OEM PARTS for everything, including filters).

The week before, I had the IPR valve replaced. Also, recently had the back pressure sensor replaced and the EGR was deleted - and turbo cleaned when the EGR was deleted last month. I also tried unplugging the ICP sensor to make sure that wasn't the issue. Dropped $6k into this thing in the past month and about to lose my mind (and wallet). All research points to either clogged EGR or bad fuel injectors, but both have been addressed, so I am not sure where to look next. No current codes showing up. No signs of leaking oil.

Ford 6.7L Power Stroke Diesel :: Hesitation / Bucking When Going In The Upper 20s / Lower 30s

Have just about 1,600 miles on tuck born on 12/14/11. Love it, but.. When going slow in subdivision I am getting some hesitation/bucking when going in the upper 20s/lower 30s. When I feel it I look down and I am usually in 3rd. Is this the transmissible thing? When it happened Sunday it felt like it was going to die. If I start off with a quicker start (to get to highway speed) it shifts fine. It just started the last few weekends......

Ford 6.0L Power Stroke Diesel :: Truck Is Starting To Surge A Bit Like ICP Sensor Going Bad

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.

Ford 6.0L Power Stroke Diesel :: Surge Or Revving When Getting Up To Cruising Speed

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.

Ford 6.0L Power Stroke Diesel :: 2003 - Surge At Idle After Driving For A While

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.

Ford 6.0L Power Stroke Diesel :: 2006 F350 - Bucking / Rough Running

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?

Ford 6.0L Power Stroke Diesel :: Slight Surge When Cold - Boost Fluctuate

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.

Ford 6.0L Power Stroke Diesel :: Rough Running / Truck Started Bucking And Hesitating At 45 MPH

Since our weather has returned to the cold side......my truck has started bucking and hesitating at 45 mph with EOT @ 130 and ECT @ 140. I can gas on it and it will clear up/let off and it would start up again once it gets below 50 mph. Once the deltas reach 150+ it clears up completely. Its never done this until this week. FICM volts are steady @ 48V. What is causing this or what to look for?

Ford 6.0L Power Stroke Diesel :: Crank / Start For A Half Second Then Shut Down - Surge On Acceleration Only

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.

Ford 6.7L Power Stroke Diesel :: Truck Lunge / Surge A Little When Stopped With Foot On Brake

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.

Ford 6.0L Power Stroke Diesel :: Sudden Buck / Surge Accompanied With Black Smoke

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.

Ford 6.0L Power Stroke Diesel :: Rough Idle And Jerking / Bucking When Torque Converter Locks Up

So, I was on my way back home driving through the middle of nowhere Utah late at night, when I had an injector tip crack. I was able to identify which one and unplug it so I could get to Grand Junction, CO (about 350 miles away) where I have family. After a power nap I started calling parts stores and found an injector from Advanced Auto Parts (I couldn't find a motorcraft reman, but I was restricted for time). Installed it and all seemed good so I hit the road again. However, nothing changed. It still had the bad miss (rough idle, jerking/bucking when the torque converter locks up) just like when I had the injector unplugged.

The truck is an early 2004 6.0. It's the number 4 injector. I finally got home and hooked up my AE scanner to discover a #4 injector circuit low P0270 code and circuit contribution/balance fault P0272. It's definitely missing because disabling it has no effect. This could be a loose connector at the injector or FICM, because I can't afford another injector right now.

Ford 6.7L Power Stroke Diesel :: 2012 F350 - Reduced Engine Power

The truck (2012 f350 6.7 lb cc 131,600 miles) started fine. Then while i was setting up the defrost i accidentally hit the ac button. Well I then hit it again to turn off. At that point the engine stalled. Which has never happened to me before. I started it back up which took a bit longer to get it to fire. It now says "Reduced engine power" and runs kinda rough. I thought well im at the end of my fuel filters life so why not change it since i had one. Well the. The FF housing broke. After replacement FF housing and filter it will no longer start. I took the filter back off and checked to see if it was cross threaded or sucking air. I checked that twice. Still no start cranks fast and strong. Codes are

P2138 something to do with the gas pedal
P0193 fuel rail sensor A high
P06A6 voltage on circuit A is whacky (paraphrasing here)
P0532 ac pressure sensor low
