Is there truely no cure for exhaust flutter on a 2002 f250 V10, bedsides putting on headers??? I have the the sound at shift points around 1800-2200 rpms. Sounds great before and after these points....
View 14 RepliesI have a 99 f250 with some procomp (325s) that are 12.5 wide with a 6in lift my superchip tuner can change the trannys shift points but I am pretty sure a new gear ratio is needed. I dont do a whole lot of off roading with it its mainly my driving around and highway rig whats a good gear ratio that would work for me
View 9 RepliesMy 2012 F250 6.2L (Gas) engine developed a noticeable drone/vibration when in drive between 1600 - 1800rpm. RPMs above and below that range is fine. But when accelerating, as soon as the RPMs reach 1600, you can feel a slight vibration through the gas pedal and a noticeable sharp draon/moan up till about 1800 or 1900 rpm, then its normal.
I took it to my ford dealer and took the service manager out for a test drive. He said that there is a drone and slight vibration withing that RPM range. He thought that the engine mounts may be loose. But aside all that, he felt something was off and wrote up the service order.
When to pick up the truck and now the service manager changes his tune and said that the drone is normal and happens on all 6.2L super duties.
To be honest, I have the feeling he is pulling my chain.
I go out of town for work for a week and come back and my 1999 F250 V10 GAS, is acting up. It started when i tried to drive it and it didn't want to shift, it would rev up to 3000+ RPMs and finally shift really hard into gear along with the speed odo not keeping up and bouncing around not wanting to work. I also had my entire gauge cluster lit up with no key and door closed. all the lights were on and it was "dinging" like the door was open and it wasn't. you would hear it when you put your ear up to the door.
So my first thought was to change the VSS (which I did) no luck. So I started wiggling wire loops under the fuse box in the cab and the "dinging" quit.. i took it for a drive and it works like nothing ever happened. Obviously I am guessing there's a short so i brought it to my mechanic and hes saying he couldn't find anything by the fuse box but he thinks its closer or even attached to the gauge cluster itself. could this be true? Why would the gauge cluster loop throw off the shift points?
The engine was just rebuilt, 7.3L diesel. New bottom end, cam and turbo also new harness for valve covers and injectors, new #8 injector(#8 cylinder lost compression). The engine cranks and idles great. Run it up to 1800rpm - 2200rpm and you get a miss or skip. Almost like the engine turns off and back on very quick, and it makes a clank noise. No codes, reading it with a OTC Genisys 4.0. I also swapped the PCM and IDM with another truck and it still does same thing. Other truck runs fine. Year model 2000 w/ 230,000 miles
View 1 RepliesHere's a link to a video where you can hear what I'm describing. The noise is most noticeable around the start (first 18 seconds) and the end of the video when I'm closest to the exhaust pipe:
YouTube ....
You may need headphones to hear it, but the engine seems to be making a bit of a puffing sound during idle. It happens completely randomly and I'm not quite sure what could be causing it.
Aside from this noise, the engine seems to idle normally, and the check engine light isn't on. I had all of the injectors out a few weeks ago for cleaning. They all appear to be working fine. I also cleaned the throttle body at that same time and ensured there were no obstructions for the air intake and filter.
What might be causing this sound? 1999 Ford F250 Super Duty 5.4L
So basically I thought it would be a great idea to degrease my motor from the top down.... After washing I start it up and drive down the road to head abunch of misfiring under heavy load or high rpm's.
My problem is that the misfiring won't throw a code. I then proceeded to buy a new ignition coil (thinking this was the problem) but with no code to go off which cylinder was bad I just switched the good ignition coil into each cylinder and starting it.
Up each time. None of them seemed to make it better. Also the injectors all seemed to be good. So what to do ?

I have a 02 F250 Super Duty XLT with a triton V8 with a automatic transmission . and when I shift into reverse after driving for a while the starter engages . It does not happen all the time . If i start up the truck and shift through or into reverse it doesn't happen . the only time it happens is when i've been driving for awhile and want to back up or park it will only do it once or twice after each drive so trying to get it to happen while in the shop is almost impossible . could this be caused by the transmission range sensor . I just had the code P0705 (transmission range sensor , A circuit input ) come on but the problem has been happening for a few weeks before that code came up .
View 6 RepliesIs it common for the exhaust to have a periodic high pitch tinny sound?
View 4 RepliesI have a 2002 F350 with the triton 5.4. For the last week it has been running like crap. I just did my plugs about a month ago. I don't know if it's a miss fire or bad fuel or I don't know what it could be. It's a popping sound coming from my exhaust and when it happens I lose power. It happens off and on. One second it will run fine and normal and the next runs bad. What it could be. Today I just changed my fuel filter and added STP octane boost and fuel injector cleaner. Haven't seen a difference yet.

View 7 RepliesI've got a 99 f250 5.4 that runs like a top. In the last 6 months I've been chasing a little problem. It doesn't happen all the time but seem to be happen more and more. While driving any speed If I let off the gas the RPM's hold at around 1500 then surges down to 1000 then back up again to 1500.
Does that 2 to 4 times then all good. Give it gas again it does it again. It kind of does it when it wants. Could be fine for a trip around then next trip it acts up again. Checked a lot of the vacuum lines, PVC valve and replaced the idle control next to the EGR valve. EGR is next.
Idles and runs fine except the surge thing..
P0401 code as well.
Got a 99 V10 blowing a lot of oil out of the exhaust pipe, to the point where I could fog the neighborhood, cylinder number 10 had original spark plug dirt down in the hole know one wanted to clean it out so I did put new plug and coil now smokes a lot, also truck has 173559 miles, did a half diesel half used motor oil flush tonight, wanted to go for 15 minutes only made it to 14 to much smoke, will put fresh oil in tomorrow, what could be the problem, piston ring blow by, intake manifold leak, burning what I think is oil could be coolant, head gasket no bubbles in oil or antifreeze and antifreeze and or oil are not mixing. Is it easier to pull the heads off with pulling the motor which looks fairly easy or leave it in the truck.

While rummaging in my garage a couple of days ago I stumbled upon a vintage Stewart Warner mechanical vacuum gauge. I would like to install it on my truck.
My question is: Where is a a good connection point for the vacuum line? Detailed direction/photo preferred as I am both Ford and V10 engine challenged.
Same question with respect to following gauges:
Volt
Oil Press
Water Temp....
My two oldest sons and I have a 1999 SD F250 4x4 with the V10 automatic. My boys burnt the trans. We had a spare that was pulled from the same year truck with the same motor. The boys installed it without me. Everything seems to work as it should, EXCEPT! 1-2 will not shift until 2800 rpm. 2-3 is the same. When I checked the install I found that the new trans has a speed input sensor on top of the housing behind the bell housing. It is Not plugged in, my harness does not have that plug. Old trans does not have that sensor. Is this the cause of the high rpm shifting?
View 14 RepliesFriend parked his well working truck and when starting it up after sitting a few days it won't shift into any gear. Lever moves as normal but the truck won't move. A soft clicking sound is the only difference to be noticed when shifting the lever. where to start? Temps are below freezing here if that matters.
View 11 Replies Ok, I have a 2004 F250 FX4 4wd 5.4L with almost 160K miles.
Sometimes, mostly when it's hot, and I go to restart it, it will crank and crank and crank, so I let off and then try again and it will start. Then other times I will have to do it 3-5 times before it starts, or it will start with real low RPM's for a second then cut out. I have been told this truck does NOT have a Fuel Pump Driver Module (My previous F-150 did). So I'm thinking the fuel pump is just temperamental. Having this issue or replaced a fuel pump before? What brands, places, etc. are good to buy at a decent price?
I tried to look online and was confused about a "midship, rear, and center tank". All I know is my truck is an extended cab and has about a 29 gallon tank.
About to do the exhaust manifold gaskets on my 03 f250.
View 3 Replies2001 F250 5.4L - I recently had my muffler changed and the pipe flange on the tailpipe up by the exhaust manifold welded back on. I haven't driven my truck much this past summer so when I took it in to get the muffler fixed the front caliper got temporarily stuck like it tends to do. It eventually freed up but in the meantime I noticed a hot oil-like smell coming from my truck from time to time. I chalked it up to either the new muffler or maybe it just smelled hot and it was instead the front brake caliper still being stuck. One day I'm driving down the interstate and I start uphill. I noticed smoke behind me and pulled over. The brake was not overheating so I got underneath the truck.
The smoke was rolling off of the exhaust pipe all the way down it all the way up near the manifold but mostly around the muffler. The smoke quickly went away while I was under the truck. I noticed it doing this only while the engine is under a load like going uphill. Just driving around town nothing is noticeable. When it does smoke I lose power. Once I slow down for awhile and then gradually speed back up things seem okay. I checked the oil.
Normally I don't lose a drop but this time I was a quart low but the oil on the stick was clean. It's been awhile since I had my oil changed but very little mileage on this change (my truck has sat awhile). My truck doesn't leave a drop of oil under it when it sits. From what I read you can remove the radiator cap and start the truck to see if it's a blown head gasket. At least that one of the things I can check easily without actually taking the plugs out even though the oil looks clean. The radiator has not lost any fluid. The transmission fluid is also good. It's been doing this for about 3 weeks.
I still drive it to and from work (about 15 miles round trip) everyday but I take it easy on the acceleration and stay on city streets. I looked into the EGR system online for my truck and instead found an EVAP purge solenoid/valve in its place on the passenger side. I don't have any service lights on the dash. I went to Autozone and had them scan it but nothing came up. I read somewhere that either the purge solenoid assembly or EGR (I can't remember) can burn up the board if it goes bad resulting in no code showing up.
I recently changed a vacuum valve out that went bad that controlled the vacuum chamber used to operate the hubs on the 4WD. The 4WD is now operational again. Assuming the head gasket is not blown, what to check for next?
is there a set of headers for my 2008 f250 5.4 rwd that will install somewhat easily without me throwing tools across the garage? I see a lot more options for the older trucks. I have a pretty annoying exhaust manifold leak and I figure I might as well throw some headers on if im gonna be in there. I really want to go for sound rather than power. I think I saw a set by flowmaster that looked decent.
