Ford Super Duty (1999-2016) :: Stumble When Idling With A Pop Every Now And Then Out The Exhaust
Sep 4, 2013
I am new to Super Dutys but i love them! Altho mine is not being so nice. It has the 5.4 in it. When its idling it has a stumble to its idle with a pop every now and then out the exhaust. It revs fine when its first started. If i pull out on to the road and start away easy its ok a slight miss but if i put the throttle down its just falls on its face. But if i get it up to cruising speed its ok as well. But even at cruising speed more then 1/8 throttle and it starts missing and falling on its face. What it could be? It smells like its running lean as well.

The other day I pulled into the parking lot put it in park and let it idle for a couple minutes, it stumbled and when I started driving off it was missing. I pulled the valve covers off and check the connection.. I drove it home and it had a bad misfire at 1500 RPMs. The truck shook violently at that RPM but when I got it up over 2000 smooths out..

06 F250 6.0 with only 65,xxx miles on it. This has happened twice and both times the engine was warm and had been cut off for less than 10 min.. When I tried to crank it back up it stumbled and idle roughly then cut off. After several attempts to re-crank it still would idle rough and I tried to give it fuel but no change, even with pedal fully depressed. Then it would die.
After sitting a few minutes it starts normal. Both times I didn't have my obd2 adapter for my torque pro. The last time it happened I went home and hooked it up and got no codes. Everything looked fine. What could it be, where should I start looking. Batteries are1.5 years old. Oil, oil filter, and both fuel filter changed about 1000 miles back. I have had the truck for 1.5 years and the oil has been changed twice.

I have a 2006 f350 6.0l. I was driving home from work and all of a sudden I had no gas pedal. It would stumble and die with a bunch of white smoke out the tail. It also is not using the turbo at all no boost. I have a edge monitor and the engine codes it's kicking out are in the picture below. I have a warranty but the dealership that we bought it from and the closet ford dealer is 30-40 mins away and they don't currently have a diesel mechanic to work on it so I would have to go almost 1hr 20 mins to get to the next dealer. Will it hurt it to drive it that far?

The last couple weeks my excursion had started to have a stumble and smoke white ate the first startup or after I let it sit for a long time. I did get progressively worse. I noticed the hpop line to the driver side head was leaking from the fitting so I rebuilt the boss fitting and now it's not leaking but when I started it up this morning it did the same thing.
If I give it throttle it clears up pretty quickly but if I let it just idle it will put white for probably 5 minutes. I have no codes showing when I looked with the scanner I don't see any other oil leaks and I don't smell a fuel leak.

I was wondering if there is a aftermarket product to give my truck a more Rumble when starting and idling.

Any such system in which they can take the key out of the ignition while leaving the vehicle running? I'd like to be able to do this for security purposes of my brand new 2015 250 if I have to run into a store or something of the like. I don't like the idea of leaving the key in the ignition and locking the doors as anyone could break the window and drive off with the truck.

I have an F-250 Ford, 2006, 6.0 turbo-diesel. Started noticing that my heat only works while running at 70 mph or more and the turbo is at around 15-20 psi. Now that it has gotten cold it is definitely an issue. Truck does not overheat, I am not able to feel heat on the hose after control vlave and I do not feel any vacuum on the line (grey) to the control valve. I have checked for leaks, changed out the fill cap, checked anti-freeze level, pulled control valve just to verify its position when opened (which it seems to stay open). It's getting really cold in the cab of that truck now.

My CC 2015 6.2 has a pretty annoying vibration when stopped at red lights, etc. isn't always there but is pretty frequent. Dealer says it is normal for the truck. I disagree. I am not sure how bad it was vibrating when the dealer had it.
Think of having a subwoofer in your truck and how it will rattle the doors,etc. seems to be behind the driver seat, coming from underneath. All stock truck.

The exhaust system from the downpipe back was stolen off this auction truck I bought, so I bought an even worse truck for parts but I'm struggling to get the exhaust off. Is there a trick to it? Does it come out going forward over the rear axle or pull out from the back? Should I just cut it and have a shop weld it back?

I have a 2001 7.3 ford the seal in the turbo went and oil went in the exhaust. lots of oil like 10 quarts. I had a rebuilt turbo installed ran great for 2 weeks then one day out of the blue started idling rough and then downward from there no power stalling etc I have my super chip scanner it read dtcs of 1249 478 1211 and 238. Is it possible the muffler is plugged with oil? or is it and ipr? 193000 miles....

I have a 2013 f350 with the 6.2L gas and automatic transmission...when it sits idling in gear or park it starts to whine or squeal for about 30 seconds then stops and starts again. it makes a horrible sound if you shut the truck off while it's making the noise... Ford has had the truck for 5 weeks and checked the motor for vacuum leaks and changed the torque converter...but it's still doing it but less frequently now but according to them it's louder. I have a video but don't know how to upload it. if you go to YouTube and search ford raptor whine it shows a raptor making the same noise also.

My 2012 f250 6.7 has what sounds like a chain spinning when idling when you give it fuel it quiets down.

My tachometer hangs out around the 600 RPM spot when I first start my truck, but lately it will end up dropping to zero when idling, and then bounce up to about the 200 RPM point when accelerating. Its not the Cam Positioning Sensor (I had that happen with my 99 7.3) and this truck runs great. I am thinking it could be at the tach.
Question is: Where does the Tachometer signal generate and does the PCM do anything with it before it sends the signal to the Tachometer? The reason for focusing on the Tach is since the engine runs and idles fine, then that tells me the PCM is receiving the correct signal from the engine and making changes accordingly. I read about a 5.4 gas engine with rain issues, but the only issues going on here is extreme cold (tonight, -15). I keep the truck garaged and when I go out, it is for purpose and then return home to a heated garage.

I own a 2001 F250, I bought a skid steer that weights 7000lbs and got a trailer that is 14,000lbs.
The truck was running fine, today was the first day I used it and I noticed by the end of the day I have oil dripping from my exhaust.
The dealership told me that the f250 is able to town that much weight, what caused it, as well as is it safe to continue to tow with it?

I have a early 2003 SD with the 5.4 triton. It has a oil leak on the passenger side, the oil blows back and gets on the exhaust.
I have been under the truck with the engine running looking at where the head meets the block and at where the valve cover meets the head and can not see a leak.
Sitting there running at idle it does not drip a drop off the engine but the entire underside of the truck is coated in oil.
I did notice that the depression around one of the upper valve cover bolts was filled with oil, I cleaned out the oil, let the truck run and it stays dry.

I plan on putting a catback exhaust on my 2016 F350 6.2 gas engine. I have always loved the sound of Flowmaster exhaust but over years have started to become slightly annoyed with the drone in the cab. Is there a exhaust system out there that is capable of sounding like Flowmaster but without the in cab drone.

I changed the IAC valve 2 months ago because my truck kept stalling when idling down on a cold start and that fixed the problem. A few days days ago when starting it started revving to 2 - 3 K and won't IDLE down now? I changed the IAC again and that didn't work. What else should I be looking at to stop it from revving so high?
2001 F250 5.4 111,000 miles super duty.

I have a 2003 f250 xlt with the 5.4l engine in it and lately my AC hasn't been standing up to the heat of the Midwest. When driving around town or on the highway my AC blows really cold but at idle you can tell a drop off in temp. Is this normal due to extreme heat or is there something I can do?

I just changed out my IAC. Truck is still idling too high. When I squeeze the host to the IAC it idles down. When I unplug the IAC the truck immediately dies.
Does the IAC talk to the the Throttle position sensor? Should this be my next part to change?
2002 F250 5.4L ....
