Ford Super Duty (1999-2016) :: 2013 F350 6.7L - High Idle At About 1000 RPM
Jan 13, 2016
New too my Ford, but anyway it's -10 Celsius. My trucks been idling for a few hours and probably will all day because of my job. Usually idles about 600rpm normally. So today the oil temp was about 80degrees Celsius. Then the truck idled up too about 1000rpm for a while. If I touch the gas it goes back to normal idle speed but then starts idling up again after 30 sec. What temp does the truck want too keep it at?

I would like to do the high idle mod with my 2006 F-350 using the upfitter switches. I've seen a couple of threads about this but they are not real clear to me and don't mention the 2006.

I've got a 2000 F350 crew cab with a camper I bought in Chile and I'm going to be driving it from the tip of south america back to the US. It's a 9 month epic family road trip. It'll involve crossing the Andes several times and going over 15,000 ft. There are roads up to 19,500 ft in various places.
My question is am I going to have problems with the altitude? What can i do about it? I've got another truck which is a unimog, it's slow as hell but has a special kind of booster gas you can inject in to the engine to get it started in very cold weather and at high altitude. I chose the F350 for the truck instead of the unimog because a unimog is slow as hell (think 40mph max speed), but it handles extreme conditions well.

I have a miss at high rpms.. I pulled this engine, manual trans, and 4x4 axle and put them in my F350 Majestic motorhome. 156,000 miles on the engine. Slightly dusted engine with good compression 375-400 (cranking and corrected for altitude). Has a little bit of a long start.
No smoke on start up unless 10 degrees or colder
No smoke when pulling either.
Glowplugs ...Good
GPR... Good
Checked resistance from IDM to injectors ...Good
History of some ether for starting before I got my hands on it. I have AE with the ford enhancement. But I am new to working on a powerstroke and new to AE.
ICP ...new
CPS...new
Oil ....new
EBP...new
Installed a pressure gauge to the drivers side upper port on my fuel bowl:
60 psi at idle
55 psi at WOT 2500-3000 rpms under a load
HPOP stabilized pressure is 2750 @ 40% duty cycle
Truck still misses (semi-intermittently) at higher rpm with a load.
Rechecked codes KOEO: None present
I visually inspected valve movement while running (idle). Did the buzz test when cold.... All injectors sounded the same when tested individually.
Did a cct when not completely warm:
P0266
p0272
Repeated the test at normal operating temperature:
P0266
Torque values on rocker arms bolts and injector holds are good. Fuel quality isn't an issue since this problem has remained for 5 tanks of fuel. What I should do next?

I have a 2013 f-350 with 58,000 miles. I'm a general contractor and drove my truck to a very nice home with decorative concrete. After I left the customers house they called my office to say I left oil stains on their driveway. I looked under the hood and noticed motor oil leaking on the front left side of the engine. I told the customer we will take care of the stain. I've never had a diesel motor leak this soon on me.
My mechanic told me to go to a Ford dealer so I did. The dealer told me that this is not covered under the warranty as it is a oil pump/brake vacuum. THE MOTOR IS LEAKING OIL. I told the dealer that the motor is leaking oil and I have a warranty that I signed up for. He told me that Ford considers this issue the same thing as an alternator.

I have a 2013 F350 Crew Cab Long bed xl with 128000 miles on it. I just barely bought it from a small dealer and had a check engine light come on for the cats.(P0420 and 0430)
I have spoke with the dealer and he assured me that he would replace the cats. He stated he had O2 sensors replaced and thought he had fixed the problem. Not sure if he replaced all sensors or just the fronts.
He has been avoiding calls lately and will not return my messages. Anyways, My question is what should I be looking for to prevent future cats from going bad. I just ordered a bluetooth OBD 2 scanner and bought the Torque Pro App.
I am not new to working on trucks but they have all been 1995 and older and i am new to anything scanner wise and do not know what I should be monitoring. If I can't get this guy to replace the cats I want to monitor everything to make sure the cats are bad.
BTW, Fuel Mileage is at best 12.3 with an extremely light foot, Driving normal it drops off to about 11.8-12. Is this a normal MPG in these trucks? I have seen post about people getting close to 16 unloaded not smashing throttle?
On another note, I just remembered that my traction control light will come on with no wheel spin at times after starting the truck and driving away.

I've noticed that when I insert the key in my 2013 F250 I hear a humming noise, if I pull the key out it goes away. What is this noise? It seems to do it as long as the key is in, but is quiet enough that you can only hear it when there isn't a lot of back round noise.

Very strange things happening with 2009 F350 Gas, first the heater blower only is now working on high, progressively has gotten worse, low settings started not working a while ago, now only high works. Just recently the strangest thing, start the truck OK, turn on radio OK, turn lights on then the radio goes off. Will bring it to dealer in a day or two if I can't figure this one out.

2005 F350 Lariat ..... I cant get my AC to work in my truck.
AC will not cycle on, Originally thought the system was low because I jumped the pressure switch and it cycled fine (But did not cool inside the vehicle). Checked the pressure and it was in the 40lb range on the low side. My blower will only blow on high but I assumed it was a defective fan speed control.. Possibly an issue with the climate control?

I'm having an issue with my 2001 F350 V10. A seriously annoying high pitched whining noise appeared a while ago, then disappeared, and has now come back.
It happens as soon as I start my truck, whether it's cold or warmed up already. it increases in pitch and loudness as I increase RPM, it also does exactly the same in neutral. As soon as I put it in gear (R, D, 2, 1) it completely disappears and will come back as soon as I shift back to P or N. Strangely, if I drive around town for a few minutes, when I get back home and shift to park the sound doesn't really come back, sometimes it will be faint but usually it's totally gone. But if I shut the truck off and turn it right back on again then it's there again.
It's coming from somewhere in the engine compartment or close but due to the nature of the sound it's very difficult to locate. I got underneath using a screwdriver as a stethoscope and listened to the transmission, transfer case, starter, oil pan and even the gastank and it doesn't sound like it's coming directly from any of them. While underneath I noticed power steering fluid leaking from the pump behind the pulley and dripping off the hose. Somehow though I don't think it's related as the sound disappears in gear and doesn't change at all when turning the wheels. I cleaned the fluid off and drove around a bit and it doesn't seem to be leaking too badly and my reservoir is totally full.
The truck otherwise is driving as good as it always has and whatever this sound is doesn't seem to be having any effect on performance (yet...) ...

Bought a 08 F350 with the 6.4 Liter, with 80k mikes on it. Was traveling up an incline. Both Turbo's were engaged, when suddenly I lost boost, and PSI dropped all the way down. They barely create any pressure now. Checked intake, also checked boots too inter cooler. All seem fine. After driving it for about five minutes at low PSI, a check engine light came on. It was a sudden loss of power.

I recently came a cross a no start issue with my truck. It is 2005 ford f350 6.0 ... Found out I have a leak in the high pressure system. When I was taking out the bolts out from the manifold I stripped out two bolts. I know ford part # w301383 is the ford bolt. But I was thinking why use that same bolt and had have that issue again later.

Alright, so here's what I've got: 2002 Ford F-350 7.3L - Unmodified, Stock, no chip, no tuner, 130K miles, been run with off-road diesel most of its life as a farm truck.
Here's what it's doing: Serious misfire in cylinders 4 and 6. At idle, mild miss. Throttle from 0 to 50 percent, runs well. Throttle from 50 percent to 100 percent, heavy miss, chugging, white smoke out the exhaust.
Here's what we've done so far:
New UVC Harnesses with updated pigtails.
Cleaned Fuel Filter Mixing screens.
Cleaned out fuel tank.
Cleaned bowl.
Changed Fuel Filter.
Changed IDMs
Changed Crank Sensor.
Inspected injectors while running to see if oil is pumping (it is).
No improvement. Where to go from here. Pulled codes, and it says Cylinder #4 and #6 High to Low Side open. We don't know what to do at this point.

I have a 2013 f350 4x4 diesel. I bought used with 80,000km on it. Started getting a bad vibration in the steering wheel around 80km/h. went too ford and replaced the track bar ball joint and steering stabilizer. After that the truck drove perfect. The next day I went and put on my new rims and tires (used tires) 20" rims with 35x12.5 r20 amp m/t tires. They used beads too balance tires. I left the tire shop and the wobble was back, I went right back too the tire shop and they took the tires and rims off too inspect more and found that one tire had kind of a flat spot and uneven wear.
So they put it on the back as too take away a little bit of the vibration, idea is too wear down that bad tire till the flat spot is gone, when I'm driving it at highway speeds it wobbles a little bit and those goes away and then comes back every 20 seconds or so, will this go away or do I need too replace that tire, buddy of mine told me too do a little burnout and maybe even out the tire a little bit but amazingly that didn't work...or could something else be wrong? Factory tires were 275/65/r20 That I had on before. Also the worst vibration is at 80km an hour but like i said it comes and goes. Will it get better?
