Ford Super Duty (1999-2016) :: 2002 F250 - IAC Changed - Truck Idling Too High
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?

Ford Super Duty (1999-2016) :: Truck Shaking When Accelerating / Idling And Driving At 1500 RPMs
I got a 2000 f250, 5.4l, I got a check engine light bout 2 weeks ago and didn't experience any driving issues. The code was p0171, just recently I've been experience troubles idling, if I let my truck idle for about 3 minutes it will want to shut off, also on acceleration the hole truck bumps, feels like I'm in an earthquake. Where I should start with this problem?

I would like to know what's happening, it seems as if idling for a minute to let my transmission temperature dial raise past the lowest line on the dial fixes or at least drastically reduces a couple issues.
The truck will deliver power much smoother off the line. I've been concerned about this for a while. The degree to which it happened wasn't constant but it seems like the truck is having trouble grabbing on (so to say) to the power coming off the line. I sort of liken it to a rope. When I give it the beans the rope goes forward but it takes a half a second or so for the truck to "grab" on to the rope. Never hard shifts, it's just delivering the power off the line or from a near stop.
Idling for a minute seems to fix this, power delivery is smooth off the line. Transmission dipstick was nice and pink but smelled slightly burnt. This is with the engine cold overnight. Didn't have time to do multiple wipes or check in the handbook for the proper methods of checking fluid, I just pulled it out quickly to take a look before heading out. Fluid covered the whole tip.
Second issue that seems to be fixed is that the battery light doesn't come on nearly as much and not for nearly as long. Typically the battery light will come on and off seemingly on its own whim during the drive. However, it seems to stay more consistently off if I idle right after startup.
Now bear in mind I baby my truck, I don't rev it high right after startup. Just low enough to cruise around the parking lot until I hit the road then I accelerate up to 40 - 60 depending on my route. I'd gladly give it the minute to warm up in the future but if I could get down to the bottom of this that'd be preferred, I doubt this is required behavior.
I do realize that these issues are not tied to startup behavior but I find it interesting that idling for a minute at startup to let the transmission gauge rise seems to mitigate these symptoms.

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

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 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.

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.

View 1 RepliesFord Super Duty (1999-2016) :: 2006 6.0 - Tachometer Drops To Zero While Idling And Bounce Up To 200 RPM?
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 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?

Ford Super Duty (1999-2016) :: 2003 F250 - AC Blows Colder While Driving Than Idling
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?

Okay, I just bought the truck (all stock except for straight pipe and cai). Nothing bullet proofed yet. It has 125,xxx miles on it and for the 4 months I had it I had no issue. Well now while idling or driving the glow plug light will flash on then off and stay off. I'll have no power and after a few minute it'll die on me. But start right back up. Is this a harness issue? 2006 6.0.....

It has 100k on the clock. I bought it about 2 years ago and only put about 500 miles on it. It is only used as a farm truck. Historically it would periodically die at idle in park. Would always start up immediately and run fine. Plenty of power.
Today the truck started up and idled a few seconds and started idling rough. It died and would restart but has zero power. Put it in gear and it would die. Did this a few times now can't even get it started.
I checked all fuses. I checked the dist cap and rotor. Don't look the best but don't think this is the problem. I get the same result on both front and rear tanks. From what I have read sounds like a fuel pump or regulator. Where is the regulator located?

Ford Super Duty (1999-2016) :: Truck Turns Over With No Key
Last night I was watching tv when my truck tried to start I thought I hit the remote start on my keys but it didn't start which I found weird. I went down stairs too see if it did anything else and it did it again it would turn over and turn over but never fire all while the keys are in my hand. At the same time the done light was stuck on and the radio went on and off. I'm pretty sure that my GEM got wet through the windshield, also Is the GEM dead or can it dry out and be ok

My 05 superduty is in the shop because it won't shift in or out of 4Hi. Ford garage says I need a new transfer case shift motor, and 4wheel drive module. They said the shift motor was full of oil. I am not really up to speed on how the shift motor works, other than it bolts externally to the transfer case, that's why it confuses me about the shift motor being saturated with oil. My truck has never leaked even a drop of any type oil, ever.
