Truck had been running with a bit of a skip and shuddered after throttle was applied and then stopped (would drop to 400 RPM and shake real bad). Had some misfire codes so I decided to do some digging. Where to start looking for air leaks pre upper fuel bowl?

Also, does this mean the air has toasted my injectors?

I have already logged 6K miles on her, crazy, but it's my job. I have pulled 5 maybe 6 trailers (form trailers, about 15K pounds loaded, this time of year). Loaded or unloaded, when I push the throttle in 2nd, 3rd gear, I feel a shudder, like transmission shudder.I know this thing throws down 800 ft. lbs. of torque, should I not be pushing it so hard? Or, what am I feeling?

This recall (14E03) has been out for several months.
What is your trucks reaction after having this recall recalibration performed?
Should I skip it?
I have a 2007 Ford F-250 6.0L that's making a vibration noise when I come to a stoplight with my foot on the brake, just idling. I just recently replaced the front brake pads this past weekend. I looked under the hood and visually checked for any obvious things that could be making the noise and did not find any, I did notice my power steering pump is damp with fluid. Now this noise only occurs when my foot is on the brake, anytime my foot is off the brake, it goes away.
I checked brake fluid level and power steering pump fluid level, both are fine except power steering fluid looks like chocolate milk. I don't know if the power steering pump would be the cause of this, but I'm going to replace it because it's leaking and I'm guessing the fluid for the power steering is way overdue. I've only owned this truck since March of this year and it has 128,000 miles on it. Hopefully this video link to youtube works, the sound in the video is the same noise that I'm hearing from the truck. Where this noise is coming from.

Black smoke is bad I think, especially when I push on the gas pedal, and I hear a bad whine or something that sounds like a very loud power steering pump whining.
I also have zero on the boost gauge. The truck barely pulls itself back home and black smoke is dribbling out of the exhaust pipe.

An issue I noticed right off the bat was that whenever I had the driver side turn signal on, and the brake was applied, the turn signal freezes.
I took apart the tail light and found a concoction of wires...I posted a diagram illustrating what it looks like.
There is this pesky Red wire that is spliced into the tail light bulb socket wire (specifically the green wire).
There is a trailer brake installed...if this means anything. I've tried disconnecting that with no luck on fixing the issue.
How to further troubleshoot would be great...electrical work is not my forte!
So I have had this happen 3 times so far. As I am driving, and step on the accelerator, I get a very bad shudder in the engine. The whole front of the truck is jumping up and down. Once I slow down it stops and is fine.
It has happened on the following three occasions but it is intermittent and does not do it all the time:
1. driving up a long grade at 45 mph for 5 minutes. I stepped on the accelerator to speed up and it happened.
2. Getting on the highway from 45 to 70 fairly quickly.
3. Once I got on the throttle heavy and got up to 80 MPH. I laid off the throttle to slow down and when I stepped on the accelerator again it happened.
I was not towing at any of these times. I do have warranty still but since I cannot always replicate it, I have not taken it to the dealer yet.
The past month or two, my garage-kept 2011 F350 6.7 with 38K miles will shudder on startup for a second or two or three then runs normal. What would be causing that? She is my every day driver, but I don't drive her every day. Seems that the longer she sits, the rougher the startup. Last time I drove her was Monday. Started her up tonight to run to the store and she shuddered for about three seconds.
View 14 RepliesSo my 06 6.0 4x4 is just about to break 200,000km and I've done most of the upgrades and work myself. (All the updates are in my Sig). My problem is that when I'm cruising and the engine is at full operating temp, if Im bellow 80-100km/h nothing but as soon as I break into that speed range about 2000rpm the truck will start to shudder. Almost feels like its not firing properly is the best way to describe it. Why this could be happening or causing it?
View 7 RepliesAnything besides a worn out Torque Converter clutch that might cause the incredible amount of shaking when the transmission tries to lock the TC?
View 6 RepliesRecently had a rear pinion leak and replaced the seal and nut. I jacked up the truck, took off wheels and felt the drag so I could duplicate once i had the new seal as I tightened the nut. I've done this only once before on my F150 years ago, but when I put the driveshaft back on and test drove it, i had shudder when not under load. So when I let off of the accelerator, it had shudder and more the faster I was going.
Obviously thinking this is a preload issue with the rear axle but would this be caused by tightening too much or too little. I had no issues before so I would think that the driveshaft itself is not the issue. I can't confirm that I got it bolted up in the exact same manner as before in relation to the flanges but still wouldn't think that to be the issue.
I bought my f 350 new from the dealer and have had many of the problems associated with this truck. Now I have a severe shudder while under acceleration when i either let off the gas or increase speed the shudder goes away. My dealer thinks it is injectors but I have little faith. Shudder seems to be rpm consistent and seems to be in the front end. oh yea it idles great and runs great except at that specific range.
View 4 RepliesWhile I am loving the fuel millage and ride of my new truck, I have my first concern. In the last few weeks i have hauled a truck bed full of dirt, and 3300 lbs of sod. both times i would use tow haul mode, and while the truck had plenty of power, it would shutter when accelerating from a stop. Mostly first gear 0-15 mph.
This is my truck with a fancy electronic controlled transmission, so on the old pickups this would be a torque converter slipping, but all the ford dealer wants to tell me is "its electrical and they want to reflash my transmission". I am at 26k miles and have less than 10k left on my warranty...
So I picked up a 53' for the racecar. When I'm hauling it on take off I'm getting a pretty good shutter out of the truck. My crew chief who owns a maintenance shop, said it's a known issue, and ford has been shimming the drive shafts.
I talked to the service writer at my dealership and he said it's a known issue and they are working on it. However, he said if they shim the driveshaft, there is a good chance it could fix the problem loaded, but then unloaded I'd have the problem. Is there a setup that's recommended?
I'm towing about 15k, but that's far from the limit of my 450.
2006 long bed with LS diff sometimes gets a fairly robust CLUNK! sound and feel when decelerating with tow mode engaged. It only happens once per 20 trips and only about a mile down the road, and it only happens once in a blue moon. It definitely is the rear end making the noise and brief shudder. Otherwise the truck runs extremely well.
I had the pumpkin off and fluid changed with Ford friction modifier added at about 100,000 miles. Truck is at 160,000 now. I just got done with a trip in the mountains of Idaho carrying a truck camper and used tow/haul mode extensively for engine braking and climbing, worked like a champ. This was just one trip of many this summer. This is about the only thing wrong that happens on my truck, but usually occurs before I get very far from the house. Should I just forget about it?
I've done the testing of hitting the brakes when the TC is locked and when it's off the shudder disappears. My question is I recently had a trans flush and both internal and external filters replaced. There was a hint of noise before then but it seems it's getting progressively worse. Could it be that they used the incorrect trans fluid? Reading through it seems as if I should follow the steps of dropping the pan and looking for signs and symptoms and then replace with the correct mercon fluid (if that's not already what's there). Then maybe some additives like shudder fix? I just want to make sure I take the correct steps to solve the problem as to not break the bank getting a new TC put in and missed something cheap and easy. Also reading it could be motor related maybe a misfire so just looking for pinpoint the problem.
View 5 RepliesI have a 06 6.0 no start . I was at a light felt a slight shudder went to take off felt another shudder and it just died. Changed fuel filters, unplugged icp no start still. No code at first now throwing p2291. Fuel pressure is at 62 when cranking. Hooked up air to the icp port and only heard air coming out of both valve covers inlets. Ipr was at I believe 60 to 65% when cranking. Little back round 2 years ago I did the whole sinister diesel top end kit and put the updated parts in. New o rings on everything that took them, new egr valve, standpipes and dummy plugs. On the injectors all new o rings and crush washers. I believe that's everything.
View 11 RepliesI just bought a 2006 F150 with the 5.4 triton motor. Under acceleration at around 40-45, the vehicle starts to skip and shudder.
Based on what I read online and the fact that I pulled a code for a #1 cyl misfire, I assumed that i just need to change the plugs, and I am trying to scheduule that now.
I just read another post about the TC not locking up due to needing the filter and fluid changed and a way to fix that would be to take OD off and see if it still does it.
When I drive with the od off, it does not do it but i am now confused since i got the one code for a misfire.
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 ?
Yesterday it was running fine today only half throttle, going up a hill no power throttle push 12 down let off the throttle engine smooths out and starts picking up speed ....
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
141,000 2003 F-350 dually
Late build 03 f350 auto, I got a p0500 code and noticed sometimes after 2rd-3rd gear engages theres a shudder or fast vibration for few secs unless i let off, it didn't start this till i took batteries out, where is the location of the vss at, I am seeing some say at each wheel, on top rear diff, on top back of trans so not real sure?
