Ford Super Duty (1999-2016) :: Idle Roughly At 60 To 75 MPH?
Truck runs and rids smooth up to about 60 MPH between 60 and 75 it gets bouncy really bouncy. Feels like the right front is whats bouncing. The not as bad on a good smooth highway but still bouncy.
I've replaced the Ujoints, Center Support Bearing on the rear drive shaft and had hit balanced. I had the front drive shaft completely rebuilt and balanced. I have new tires.
Shop said suspension needed done. Could that be the cause of the bounce or is it a CVJ on the front (feels like the front bouncing)
Side note, when the hubs are locked in there's a knocking when i turn hard right.
Ford Super Duty (1999-2016) :: Intermittent Stalls At Idle And Hard Start
As a follow up to my problem of intermittent stall and hard start, it is getting more pronounced. Now, every once in a while, it will start. Mostly it will not start.
This morning I connected an OBD2 meter with the key on and engine off. It told me that there are no DTC's. As I was attempting to run enhanced DTC's the code reader lost link with the computer. The connection icon was on but it lost the link. At one point, after several tries, I got the link back but it didn't last too long before it was lost again.
This is the same symptom that I have with running the engine. It will run and then shut off. After a hard start, it will start and run just fine and then shut off again.
My question is this. Can I still have power to the PCM and loose power to the processor? Is there a fuse or relay that could be causing this problem? If not, could the problem be a faulty PCM.
Ford Super Duty (1999-2016) :: Stumble And White Smoke At First Start Up After Sitting For Long
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.
Ford Super Duty (1999-2016) :: 6.8L V10 Rough Idle And Hard Misfire
My F53 motorhome has a rough idle and hard misfire but is not setting any codes. I've put new plugs in it and not change.

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.

I have a 2002 F-450 crew cab 2wd automatic 7.3 diesel with 298k on the body and about 120k on a Jasper engine. About a month ago I started it in the morning to let it warm up. Went to make coffee. Came back and it had died. It was low on fuel and I didn't pay attention. Played hell getting it primed back up. Now if I don't let it warm up for twenty minutes it won't run worth a flip and has been dying out. Changed fuel filter. Unplugged ICP. No change. When I crank it it will turn over for about thirty seconds then oil pressure gauge moves, then engine starts to run very roughly. It will die. I repeat a few times. It will eventually start and start and stay running. Blows whitish grey smoke until it warms up. No loss in power till CEL comes on. Still not too much loss. Sometimes it takes a long time to get it running. Sometimes it will die after I get out of the driveway if I don't let it warm up. Truck was serviced maybe 3000 miles ago. No water in fuel. New fuel filter. New air filter. It is a company truck. I work for a small company building cell towers.

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..
View 1 RepliesFord Super Duty (1999-2016) :: Hard To Start When Cold - White / Grey Smoke At Start Up?
Truck: 1999 Ford Truck F 350 4WD Super Duty V8-7.3L DSL Turbo VIN F
Problem: Especially when it is cold outside . . . The truck takes forever to start and while doing so a ton of white/grey smoke comes out of the exhaust.
My starting schema: Turn the key on have the gas pedal pushed to the floor until the "wait to start" light goes out. Then, I turn the key off and back on while still pressing the gas pedal all the way down. When the "wait to start" light goes out again I remove my foot from the pedal and try to start it. I never leave it cranking for more than 5-7 seconds. If, after trying this process several times I will not push the pedal in at all. Also, sometimes I will leave the pedal pushed in while I am cranking it over.
The truck used to start after a couple of tries but lately it won't start at all, even after 20 tries. Sometimes it will spin up for a second as if the engine gets going but then just doesn't continue running. When it is warm out it will usually start after a few tries but doesn't seem normal to me. After I first bought the truck(used) it would start up within half a second after turning the key.This all started after I had to fix an o-ring that was damaged on the top/back of the motor that was dumping all my oil out of the top/back of the motor.
Ford Super Duty (1999-2016) :: Shift Very Hard After Idle In Gear (stop At Signal) Occasionally?
So, in my 99 Bounder RV (F53 chassis), V10
I think it has a 4R100 transmission in it (I have not verified this).
I had the oil and filter changed about 10K ago.
Runs and shifts fine .... then I stop and idle with it in gear (say stopped in traffic for a few minutes).
Now the thing shifts super hard! I actually get rubber in all gears.
So I pull over, shut it off. Restart the unit and everything is fine again.
It does this very consistently!
I went to the local transmission shop. They said with 110K in an RV it could be anything and I should think about letting them rebuild it.
Now that is something I would do ... not diagnose a problem and just rebuild it. I thought a "professional" would actually look for the problem first.
I don't want to rebuild the transmission if there is small item that will fix this.
Ford Super Duty (1999-2016) :: Steering Stiff / Extremely Hard To Turn At Low Speed Just Off Idle
My steering got real "heavy" almost as if I had no power steering so I replaced the power steering pump. The steering got a little easier but is still very stiff. It's extremely hard to turn at low speed just off idle...I have to rev the engine a bit to get it to turn.This is on my 1999 7.3 f350...I've ran 33" and 35" tires on it it's whole life and this is the first PS pump I've replaced since 1999...never replaced the steering box.
View 9 RepliesFord Super Duty (1999-2016) :: 2001 - Suddenly High Idle / No Blower And Hard Shift
My '01 recently seized up and a buddy determined it was the AC pump. Replaced the belt with the bypass version. A month later, I moved across the state to Iowa. A couple weeks into living here I turned the truck on and it was idling really high (about 2500-3000) but would settle down to around 1100 when put in gear. However, shifting into gear is causing a progressively worse "jump" into gear. Hadn't really had the money or the time to take it in so I let it mostly sit unless I absolutely needed the truck.
Today, the idle is still high and does seem to cycle a bit in that it will rev up close to 3000 then settle back down around 2200 or so and then rev back up again and so on. I backed it down the drive into the sun for a little warmth and it darn near jumped a foot when I shifted. I turned the heater on defrost so I could clear the windshield and absolutely nothing came out.
I can't get into a garage for a few days to get it hooked up for diagnostics. So I thought I'd try here. My research leads me to think part of my problem may be a vacuum leak and/or maybe a sensor somewhere.
Ford - Explorer :: 2005 - Idle Roughly - Hard Start?
I have a 2005 Ford Explorer 4wd with 4.0 SOHC 6 cyl Flex Fuel. For months the vehicle has idle rough and increasingly becoming difficult to start. I decicded to replace the spark plugs and wires hoping to solve this issue! gap set to 052. When I started the vehicle it went into engine fail safe mode and wrench light came on. I then replaced the TPS on the throttle body and had no diference (I may have installed incorrectly! when I put it on the armature felt like it broke free inside the sensor). DTC codes read P0223, P2106, P2110 and with P0122 pending, P0223 pdg, P2106 pdg, & 2110 pdg.
With the old tps installed and wiring harness disconnected the truck will start in fail safe mode, but will not start at all with wire harness connected. A volt meter reads at computer end of wire plug 3.69 volts at pin one (gray/red wire +) and pin three (gray/white wire -) with key to on but not running.
Ford Super Duty (1999-2016) :: Hard To Start Now Not Cranking
Bought 02 350 DRW, started hard first day, now not cranking. Seen a post on neutral transmission switch and mine is not lining up, but need to adjust the rod out of transmission also? I was able to match lines on switch but with flanges on fitting it will move back out of place when moving it to fit in bolts.
View 4 RepliesFord Super Duty (1999-2016) :: 2006 - Hard Start - Won't Crank?
I've been having sporadic starting issues with my truck since the fall. I had the spark plugs changed but that did not work. The hard starts usually occur when the engine is hot....after filling gas or just running into the grocery store. The engine seems to turn over slowly the first try and won't start. The second or third try the engine turns over normally and the truck usually starts.
I just got back from a 90 minute drive and shut off the truck for 5 minutes and now it won't even turn over. My thought is that it can't be the battery....its been charging for 90 minutes. Headlights are strong, wipers work fast, fan blows hard. That being said I think alternator or battery can be ruled out?
Where do I look next? Starter? Is there a starter solenoid that could be defective?
Ford Super Duty (1999-2016) :: 2001 F250 - Hard To Start
My '01 f250 7.3 has gotten hard to start. It seems to maybe be due to cooler weather, but not always. I have been told that there is some sort of valve in the fuel tank that could possibly cause this when the fuel gets around a 1/4 tank or so. But, it's doing it at any fuel level. But it doesn't do it all the time. I do notice it more in cooler weather. Anyway, when I try to crank it, I'll let the "wait to start" light go off and then wait a bit more. I'll turn it over and it almost as if the batteries are weak.
I'll stop and give it a few seconds and turn it again and it will normally start. But sometimes I'll do this 5 or 6 times and it will finally fire. But the more I have to try, it's like fuel builds in the cylinders and it smoke like a coal train for a minute or so. Almost like gas motor that has been flooded. But the smoke burns off and it runs like a top. I was thinking the batteries may be weak , but sometimes the starter will spin the motor with no trouble at all. I'm at a loss. Is it possible for fuel to drain from the system causing it to have to reprime itself? Here lately the smoking has me concerned even though it clears up.
Ford Super Duty (1999-2016) :: Hard To Start / Zero Power When Put It In Drive
Recently purchased a 99 F250 SD w/ V-10 Triton which purrs like a kitten and drives great until I turn it off and then re-start. It has trouble re-starting and then when started and put in drive...won't go anywhere. Zero power. Oddly, in reverse it goes. Getting decent flow from exhaust. No vacuum leaks I can find. No check engine light on either. Strange.
View 7 RepliesFord Super Duty (1999-2016) :: 2002 F250 V10 Misfire When Driving Roughly Between 30 - 40 MPH
OK, not sure where to start so here goes. I have an 02' f-250 with the v-10. I just had some minor front end body work done and when I got it back I noticed that it just didn't feel right while driving. When I start it, I notice a small misfire while I stand next to the exhaust outlet. Nothing too bad, still runs great. Shortly thereafter I started noticing a more habitual missing while driving. Roughly between 30-40 mph and around 12-1500 rpm the truck feel like the driveline is about to pickle fork the truck. If I let off the gas or step on it, the vibration goes away. And very intermittent.
It will only do it when the truck is warmed up. If I only drive about a mile, it won't do it, yet if I turn around and head back, there it is! Now the weird part. I for reasons I won't get into, I left my ignition on and drained the battery. I just replaced it and for the last 2 days nothing. Nt even a misfire. Now today here it is again. I have read all over the forums for this exact problem and cannot find my exact problem. I have replaced the plugs with Autolites and cleaned the coils as well as the boots and applied a small amount of dielectric grease to the top of the plug. The boots are cleaned and not a sign of cracking or wear.
I replaced the PCV valve and nothing. All the plugs looked exactly the same. Light chocolate in color. Not one looked different than the other. I took them out again last week to verify the plugs weren't bad and the new ones all looked the same as well. I cleaned the MAF sensor also. Just cannot figure out what could be doing this all of the sudden. I don't see where anything wasn't plugged back together when it was being worked on and why would a new battery make it go away for a short time? Oh, and lastly, I have a superchips programmer that came with the truck and there are no codes showing and my check engine light has never came on yet.
Ford Super Duty (1999-2016) :: No Gas Pedal / Stumble And Die With A Bunch Of White Smoke Out The Tail
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?
