Ford Super Duty (1999-2016) :: Intermittent Accelerator / No Response Just Goes To Idle
2002 Ford F350 Powerstroke, 7.3L, Automatic, 4 wheel drive .... AFE Stage II Intake, 5" full exhaust, TS 6-position tuner chip, Swamps 140lb injectors
Intermittent accelerator problem: no response, just goes to idle. Runs perfectly with no other issues but zero response when the accelerator it pressed. There seems to be no pattern to the problem as this happens at any speed/position on the pedal. When the accelerator goes out the check engine light in the lower left corner comes on. All fuses are good.
Symptoms began a month or so ago feeling like an occasional 'hiccup' or hesitation. Symptoms occurred a few more times until a couple of weeks ago (Friday, 2/20/15) when it left my son stranded a few miles from home. He was able to limp it to a parking lot and we left it over night and went and towed it back to the house the next morning. The truck started and ran fine just no accelerator so we towed it idling so we would have power steering/brakes, etc. As we neared the house the engine light went out and the accelerator began working and he was able to drive the truck the remaining 1/2 mile home.
Most all of the research I did came back with the Throttle Position Sensor as the culprit. I was able to order one (the complete accelerator pedal assembly that is*) at a Napa store in a nearby town and picked it up on Tuesday (2/24). As soon as I installed it everything worked fine.
As an aside, I have read a lot about the mid-2001 switch from the units with the TPS (Throttle Position Sensor) and IVS (Idle Validation Switch) as separately connected units to the 'new' style where these parts are combined into one and there is a single 5-wire connector. Being a 2002 there was no question as to which one I had. Just be aware of the difference. Also, this part is simple to change. The connector has a clip that you pinch down on with your thumb and then pull off. I use my little electric impact with 1/4" extension and a 10mm socket. Zip, zip, zip an you're done. It takes me longer to get my tools out.
A few days later on Friday (2/27) it presented the sporadic accelerator symptom a couple of times again but was able to get the truck home. The next morning I unplugged, cleaned (CRC Contact Cleaner), and dabbed into the connector a small amount of dielectric grease to insure good connection. (I had read that in my research as well). That seemed to work beautifully and he said it ran fine all day and until the next afternoon (Sunday, 3/1) when it began acting up yet again.
I continued to research and could find nothing that would suggest anything other than the Throttle Position Sensor. I read that some other folks had gone through a few of the Napa/aftermarket units though so I began thinking that maybe I had just gotten a bad unit.
Ford Super Duty (1999-2016) :: ABS / Check Engine And Wrench Light All On At Once
Pulled into work and the truck was running fine then i got out and shut it off and went to start it again to move it 5 minutes later and it would start and misfire and chug and the wrench light came on as well as check engine and abs. I replaced the throttle body motor with the doorman part and I'm installing a new electronic pedal today as well.
The weird part is the chugging as i replaced all plugs and coil packs, plugs are champion double platinum. when all this started it was raining pretty hard out side I've cleaned all plugs with compressed air and used dietetic grease on most until i ran out. Truck is a 2006 f250 with 3v 5.4 automatic... Truck is my work truck and i am stumped on this .....could cam sensors cause the same issues? What about egr valve?
Ford Super Duty (1999-2016) :: Wrench Light Came On And F250 Will Not Start
We hadn't started our 2008 F250 in about 2 weeks. It got really cold the last few nights, about 10 degrees, so I thought I should start it. It started and ran for about 30 seconds, stalked, then the wrench light came on and it will not start. The truck only has 84k original miles and we just had a tune up about 8 months ago.

Having problem with oil cooler pump throwing the wrench light? Dealer says it cools the oil and mine could be clogged a bit.. cost of total job around 8-10 k. And take cab off.
It seems when engine gets hot wrench light comes on cause not cooling oil down properly... it overheated. Gauges were very high.. Once when I was in full boost towing a ranger up a hill. First time it ever happened.. pulled over for 5 mins than started temp went back normal and finished tow no problem after that cause I kept boost lower!
Ford Super Duty (1999-2016) :: 2007 F250 - Wrench Dash Light Turned On
2007 ford f250 .... 200k on it ....
Just had refurb engine installed with new oil elements as well. On a 9 hr road trip, the wrench light came on but no other warning lights.
No stock gauges showed any raises in levels.
No noticed loss of power at all.
The light would only come on once I drove at about 75 mph for about 10+ miles. It would not turn off when i slowed down, but when I would kill the truck and restart it, the light would be off. Just driving in town or on the highway briefly, nothing comes on. Took it in to oreillys to get scanned and they tell me a few codes pull up but none of them are valid. What would trigger the wrench?
Ford Super Duty (1999-2016) :: Power Loss - Wrench Light / Drain Water Separator
So today. I filled my truck full of diesel. when I started it back up, it through the wrench light plus drain water separator. What it could be I have a loss in power. wont get over 45mph.

I was changing the vct solenoid on the driver side and I dropped a 3-4" Allen wrench inside the hole. I tool the valve cover off and can't see much down inside. Its not to the right by the cams, I think it fell down in front by the timing chains but I can't see it caught on a chain or anywhere. I drained the oil and took the filter off and looked in the oil pan with a snake camera, no luck.

I have a 2015 SD with only 4100 miles on it. This has happened to me twice. Both times, traveling slowly at idle or just above. Anyway, tried to give it a little gas, and -----nothing. Lightly pumped the throttle a couple of quick times and back on line. The motor didn't die, but there was no response to the throttle at all. The first time, I thought maybe it was something I did. Then it doesn't happen for a month and a half and then again, in heavy traffic in the rain. Haven't had my first service yet, and you can bet I'll tell them about it. Almost felt like a two-stroke that had loaded up?

2003 f250 4x4 7.3 auto
Been an ongoing problem with truck, pedal would sometimes lose all response. truck starts and idles fine but will not throttle up and all needles on the instrument cluster are at their rested position and the odometer doesn't even light up, however all the backlights still work fine.
The owner said that a 10 amp fuse on the bottom row of the fuse panel would occasionally blow, and that's when the pedal would go dead, he would replace it and keep driving till it blew again... usually about a week. I checked all fuses on the truck tonight and all are fine.
Unplugged the connector on the pedal sensor and cleaned and reinstalled and still wont throttle up. I am not sure what number the fuse was that he kept replacing but i *think* it was a cluster fuse. Is their an correlation between the cluster stopping the pedal sensor from working or vice versa?
Ford Super Duty (1999-2016) :: 2015 F250 - Lousy Throttle Response
Took delivery of my 2015 F250 in June with 2WD and the 6.2 gas engine. What I thought to be a slow throttle response seems to be more of a quick shifting transmission according to two different dealerships. My 6 speed automatic has already shifted to 4th gear at only 25-30 MPH. My Dodge Hemi I sold never had shifts as quick as this and I think it's to quick. My question is....is there a way to change these shift points so I get more speed before it shifts into the higher gears?

My friend has a F250. He was getting terrible mileage and the mechanic he took it to replaced the intake gaskets. After that the mileage went to 12 and he was happy. Now its down to 6-8, just highway. It seems to me the throttle response is terrible compared to my dad's 01 V10. And it sounds terrible. Exhaust manifolds aren't leaking that I see.
I've got AE and have hooked it up, but I'm really not very familiar with these trucks. I don't get any codes that would relate to anything. Had one trans sensor code but that was about it. Key on engine running test didn't say anything.
Ford Super Duty (1999-2016) :: 2005 F250 - Quick Throttle Response
2005 f250 4x4 , crew cab v10. Just put on my magnaflow muffler and gotta say, What a difference that makes! Can't wait to get the k&n intake kit and see what that will do. I see that my truck has the electronic throttle control instead of the previous v10s with the cable. I am wondering, is there any way to get quicker throttle response like with the old cable style throttle? Just seems real sluggish to rap up the rpm in park with no load on it.

I have had this truck for several years. I have only had a few issues. I've heard of engine noise issues but I have never had any until now. My 5.4 is making a knocking sound that just started. It goes away if I tap the accelerator. It has over 200,000 miles on it. I change the oil every 3000-4000 miles. No additives and always conventional 5-20. Is this a serious issue? I've seen people talk about using thicker oil but I'm very hesitant.

I have roughly 104k miles. The weather is trying to get colder. Lows of 45 highs of 80 right now. Last week I was accelerating on to the highway and the truck seemed to have trouble shifting. I hit the accelerator and it did not shift. It would continue to increase in speed but very slowly and would even tend to kind of sputter a little. My engine light came on and has gone off and on several times since then. This has occurred several more times and is always when I hit the highway.

So, I'm slowly but surely eliminating a terribly shaky front end on my 2002 F-250 7.3L 4x4. First was a new carrier joint on the front drive shaft. Didn't work much, but the shop said the darn thing was falling apart. Next thing I did was new wheel bearings and manual hubs. Less vibration for sure. But the last remaining issue, in terms of vibration, is that when I let go of the Accelerator going at any speed above 60 MPH, it makes a horrible horrible noise, and I could feel a vibration. It shakes the whole truck, but I can very noticeably feel it directly in the gas pedal. It's really only an issue during deceleration. What could it be??? Drive shaft U-joints? Torque Converter? Something else in the Front End? Something in the engine even?? I don't exactly have the funds to tackle every possible solution.
View 1 RepliesFord Super Duty (1999-2016) :: Scary Clunk In Drivetrain When Take Foot Off The Accelerator
I have a 2001 F250 7.3 with 175K.
Here is the situation. There is a disturbing clunk when I take my foot off the accelerator and a corresponding clunk when I push back down on the accelerator. This only occurs when the vehicle is not under load. That is, it does not happen when going up hill or on any sort of an incline. It does not happen when the automatic transmission shifts. It does not happen shifting into reverse or drive.
It does not happen when starting or stopping. It only happens when I am at 40-60, or so, miles an hour and let off the accelerator and/or press the accelerator again. It appears that I can carefully feather the accelerator to eliminate or, at least, minimize the clunk. I have crawled under the truck and it looks like all the U-joints are tight, I have lubricated the slip-yoke (although when twisted there is, like a mm of play when this is twisted, not much but a very little).
The rear-differential pinion appears to be tight (no side-to-side play or up-and-down play, or at least I can't make it move with my hands). However, when the truck is in neutral the entire driveshaft is able to rotate a half inch, or so, all the way up and down the drive train. That is, the transfer case and the rear differential appear to have a little rotational play in them, but I am guessing this is pretty normal. When in park the entire driveline seems solid.
I have seen from some of the other posts that this sort of clunking can come from leaf springs, hangers and such but since this clunk seems so isolated to acceleration changes when the vehicle is not under load, I doesn't seem like this would be the issue. No clunk when shifting, turning, bumps etc. Everything seems perfect until I am on a gentle downhill or flat and let off the accelerator. Doesn't appear to clunk when going down a steeper decline. All this gets me to thinking that the clunk is caused whenever the driveshaft rotation gets ahead of or behind the rotation in the rear differential.
Ford Super Duty (1999-2016) :: Ticking Noise Coming From Right Side When Push The Accelerator
2002 Ford F-250 5.4l ... What is the difference in sound between a lifter tick and an exhaust leak? I have a ticking noise, almost sounds more like a puff of air noise, it only makes the noise when I push the accelerator and is coming from the right side. Noise is most noticeable if I put my head under the passenger side front fender. I am guessing I have an exhaust leak somewhere between the heads at cat but just wondering about the difference in sound. I'd think if it were the lifters they would tick at idle, right? The truck sounds great at idle (after doing a tune up) I just want to get rid of this annoying tick when I accelerate.

I need fixing my 2003 f350 6.0 diesel, I have been working on this truck for a while and still am having problems, here was the original symptoms:
-Hard start or no start on a sunny day
-Rough idle for 10-15 minutes
-Rough shaking in the low RPMs (35 mph)[/COLOR]
-Slow response from the gas pedal
-boost would only get to 14
My dad and I then did many things to the truck in the shop, those things are:
-Air test and replacement of coupling going into oil branches (next to HPOP)
-Replaced EGR valve (no good)
-Replaced ICP sensor (leaking oil)
-Replaced ICP sensor and IPR valve piggtails (due to frayed wires)
-Cleaned Turbo
-Cut MAP sensor hose and reattached it (spliced on the end)
-New battery
-Performed a bubble test and found two bad injectors on passenger side (injectors #5 and #7)
-Cleaned and lubed tops of injectors
-Replaced O rings and copper crush washers on all injectors
-Replaced nipple cup O rings (tight)
-Blew out injector cups
-Bubble tested after injectors put back in (no more bubbles)
-New FICM, EGR cooler and oil cooler were already installed
-Ohm'd main engine wiring harness (good to go)
-Taped up frayed wires on fan clutch connection
-Increased wire gauge on the positive jumper between both batteries
-Sanded each ground on the batteries and engine, cleaned battery clamps, lithium greased connection points.
-Checked fuel for air (no air)
-Checked fuel psi (85 psi, plenty)
-Oil changed
After doing all of this (diagnosing as we fixed each thing) we now fixed many things including the hard/no start problem. Now, for the first three to five minutes:
-It starts right up
-Runs perfectly, no shake and instant response from the gas pedal and turbo
-Boost goes to 28
-ICP is 800-950 on idle
-IPR is 25-26.9% closed
After five minutes however:
-Starts to shake
-IPR % starts to raise
-Received no response from gas pedal (absolutely no power)
This truck has been torn apart like 8 times and I have to do it on my spare time.
