Ford Super Duty (1999-2016) :: Slight Rough Idle After Couple Of Minutes When Start The Truck
I have a 99 F350 with a V10. I just replaced all the spark plugs and a bad coil which solved the very bad misfire I had going on. I also just changed the fuel pump and fuel filter.
When I start the truck, it idles just fine, nice and smooth. After sitting there for a short bit, maybe a couple minutes, it starts to idle rough, not so rough that it's about to shut off, just a little rough. This lasts maybe a minute and then goes back to nice and smooth and stays that way.
I've thought maybe the EGR valve or Idle air control valve but I'm not sure if I'm way off or sort of close.
Ford Super Duty (1999-2016) :: 2000 F350 - No Vacuum Signal To Heat Controls / Slight Miss At Idle
On a 2000 F-350 with 5.4 engine, where does the vacuum line enter the cab? I got a truck in with no vacuum signal to the heat controls, and it has a slight miss at idle. Both of these are signs of a vacuum leak, but i can not find the line going into the cab.

View 2 RepliesFord Super Duty (1999-2016) :: 2003 - Hesitation / Truck Shutting Off Randomly
I have a 03 F250 5.4 4x4 auto, last year I had a problem with the truck shutting off randomly. So after doing all the dumb stuff and research I ended up concluding that the FP relay was acting up and my understanding is that, it is located in the fuse block. So not wanting to replace it I wired up my own relay next to the safety switch in the passenger side kick panel and it has been fine ever since. I did put a new pump in it (Cali emissions) Now to present day-
Over the past month my truck would have a slight hesitation problem when accelerating on the highway/up grade. The issue was it would go away for a while when you would shut the truck off and be good for a while. Well then it started happening all the time.
I knew I was do for a tune up (215,000) so I did all the plugs, COP's, fuel filter and a PM. It got a lot better but was still there at the top end. So after doing a lot of research I found a lot of people having the same issues, so for testing purposes I cut the CAT out and installed a section of flex pipe. (Iwill be installing the cat back in)
So last night I take it out and its even worse...I went don to my buddy's place and hooked up a Versus and got no codes at all, no misfires on the counter..absolutely nothing. So I did what I should have done in the beginning and duct taped a fuel pressure gauge to the windshield and took off.
At idle I have 30 or so PSI, and when it was fine it would stay around that, when it started acting up it would drop to 5-2psi under load and go back to 30 or so PSI at idle. The other thing is now I only have 1/4 tank of gas.
What I am concluding is that the pump is getting hot and weak, because when I had a full fuel tank it was better and now I have less fuel to cool the pump and it is happening faster. Should I just throw another new pump in it? Or go after a voltage problem to the pump?
Ford Super Duty (1999-2016) :: 2003 V10 - Slight Miss With Pending P0171 Code
I just purchased a 2003 F250 Super Duty with the 6.8L V10 It has really high miles on it as it was a landscaping companies fleet truck. I'm sure that it was pretty well serviced as it has 300K miles on it and it's still running pretty decent.
I picked up the truck and I have to get the smog done soon. It idles with what I can only describe as a slight miss and it runs and drives great. seems to have plenty of power for the miles that's on it.
There is no active CEL on but I scanned the OBDII system and found a P0171 Lean bank 1 code in the pending codes list of the scanner. I guess this year engine doesn't have an EGR Valve or DPFE sensor because I've looked high and low for it and there non existent on this engine.
I've checked for vacuum leaks by spraying brake cleaner or carb cleaner all over the place and it makes no difference and all the vacuum lines and connections look okay.
When it's running It does sound like a vacuum leak right behind the top of the plastic throttle body but I can't find it, I don't know if this big *** engine just sucks that much air or what.
Like I said I need to smog this thing soon and I don't want it to fail if it's missing or has another issue. The fuel injectors look new and one coil pack looks like it's a replacement...
Ford Super Duty (1999-2016) :: At 45 - 55 Mph Shake Violently?
I am getting what i think is death wobble at around 45-55 mph in my 2012 but not near as violent as others/videos have described. I do not have a lift but i do have 35x55x12 mud tires. I got an alignment but it is still happening. I have read that it is usually caster but i thought this was only in lifted trucks? I am putting a 3.5 inch lift on it to better clear my tires in a couple of weeks and it comes with a trac bar relocation bracket. Will this fix the issue? I have checked tie rods/ball joints as well and they seem ok. Will the relocation bar fix the issue? I also have dual stabilizers on it. That firm up the steering after i put the tires on but the intermittent wobble is still there. Most of my driving is between 45-55mph so it can become annoying.

My truck is a 2000 F-350 (with front leaf springs). It has developed a significant shake in the front end. I have read much information about "Death Wobble," but I am not sure that's what my problem is. The truck shakes back and forth and the steering wheel moves what feels like several inches as well. I have already replaced the tie-rod and drag link, thinking this would solve the problem. The truck seemed better at first, but the shimmying came back.
The reason I replaced those particular parts was that I noticed the heim joints at both ends of the drag link had a lot of play in them. So, now I am trying to re-diagnose the problem. With the wheels off the ground, I cannot detect any play in either wheel when I try to move the tire by grabbing it at the top. I did notice that there is 1/4'' to 3/8'' of play in the steering box arm that connects to the drag link.
I am not sure if this is normal or not. The truck has a little less than 150,000 miles on it, so I am sure several different parts could be worn. However, after examining it quite a bit, I cannot see any obvious problems.
Ford Super Duty (1999-2016) :: Getting A Shake Throughout The Entire Truck Above 50 MPH
Removing oem aluminum for oem Steel wheels. After going through two sets of tires, having driveshaft rebuilt for no reason, new shocks, new rotors and pads, I'm 100,000.00 percent positive one of the aluminum wheels is out of round. From 50+ MPH I start getting a shake throughout the entire truck, faster you get it gets a little worse. I can't feel it in my steering wheel though? And if I rotate tires it stays the same, my buddy is giving me a really decent set of steel wheels from his 2003 xl f250 work truck and the local powder coat shop told me 100 per Tire for sand blast primer and then my choice of powder coat. Steel will always be stronger and run truer than aluminum and winter shouldn't be a problem since I do upkeep my vehicle. OR just buy a 16x10 aluminum wheels and FINALLY do my 4" lift with 35's and sell my almost new 285 tires...

I have a 2012 F-250 crew cab 4x4 XL, 6.7L. I recently added a set of factory 20" wheels from a 2017 F-250 Lariat and put a set of new Nitto Ridge Grappler tires, 295/60/20, on the wheels. Since adding the new wheels tires, I've had a shake inside the cab when traveling between 70-75mph that we can't seem to pinpoint. It certainly feels like a balance issue, but we've road forced every wheel/tire and even had Nitto replace one tire that had a road force reading outside of the "normal" guidelines. Thought for sure that one tire was the issue, but installed last night and still the same issue. The shake is felt mostly in the front and rear seats. The passenger front seat shakes fairly vigorously. We've re-balanced all 4 wheels and tires, I've had the front end re-aligned, twice. I never had any issue with the factory wheels (which were the ford factory steel wheels 17"), even after adding larger tires. I can't imagine it's the new lighter aluminum wheels since people put on lighter after market wheels every day.

I got an 03 f250 with a 10 inch lift on 40x14.50 tires on 20x10 fuel hostage wheels. They rub my springs pretty bad when trying to make even the slightest kind of tight turn and the sound they make when they rub is even worse than them actually rubbing. My question is should i stay with this tire and wheel setup and try to get some 6061 billet aluminum 2 inch spacers? (I'm not sure about going that route though because of what i heard about spacers) or go down to some 38s with a 20x14 wheel that hopefully would push the tire away from the hub like spacers would do. I'm leaning more towards going to 38s because of the rubbing and also because I feel they might look better on the 10 inch lift rather than the 40s but dont know whats the best thing to do.

I have an 09 F350 (116,000 miles) that I have only owned for about 3 months. I got it pretty cheap but it did have a front end issue. Drives fine most of the time but hit a bump just wrong at highway speed and it goes into a shake and wobble that feels like you just blew a front tire. Took it into my shop, not the dealer and was told I pretty much need a front end rebuild. Kinda what I figured I would hear.
View 4 RepliesFord Super Duty (1999-2016) :: 2005 F350 - Shake Worse At 60 - 65 MPH When Towing
I know there are tons of threads on this and ive spent hours reading through them. but there are a few differences to mine.
2005 F350 6.0l regular cab long box. 4" lift on Duratec 33". Wheels balanced, driveshafts balanced, all u-joints checked and 1 was replaced (made no noticeable difference), all new brakes and rotors recently(due to wear)
When im not towing, vibration is noticeable between 60-65, but its only slight and i can live with it. Its felt in the seat and not the wheel.
There is also a very low grinding/pulsing feeling that happens as i am slowing down from highway speeds starting at around 10 mph until I completely stop. Its not the brakes and feels driveline to me. Can only be felt at these very low speeds while decelerating/coasting. Feel it in the seat and not the wheel. Not the end of the world but i have a feeling its related to my high speed issues. It is not felt on acceleration and I don't feel it when I am moving around parking lots/etc. ONLY when decelerating from highway speeds.
When I am towing the vibration randomly gets really bad right around 65mph the whole truck shakes and its very uncomfortable. It doesn't matter if I am on the gas or not, hill or no hill. If i slow down to 60 it goes away. It is very rhythmic with road speed (3 pulses with a slight pause)
Been doing a lot more towing lately and its bugging me. I keep falling back on tires, but not quite ready to bite the bullet on new tires as the ones on it still have tons of life left.
Ford Super Duty (1999-2016) :: 2011 F250 Shake At Highway Speeds Around 70 To 75 MPH
I have a 2011 f250 6.2 cclb and it shakes around 70 to 75 mph. Not terribly but enough to annoy the crap out of me. Now I have put new tires on it recently, new Rancho 9900 adjustable shocks, I have it aligned regularly and tires rotated and balanced every 5000 miles or so. I have had two dealerships look at and my local shop and they can't see anything visibly wrong with it.

I've got a 2003 6.0 that's got a rough idle and low power situation. Doesn't matter hot or cold it has a hard start issue but when it finally starts it has a rough idle, sometimes it has low power on take off but not always. FICM has 48.8 volts coming out, exhaust just had a new y-pipe (had a cracked bellow) absolutely no smoke coming out. When I drive it hard it's like a rocket no rough spots just did oil with filters and fuel filters, blue spring upgrade, and cleaned out the turbo.
