Ford 6.0L Power Stroke Diesel :: Shakes At Idle / Poor Throttle Response
I just recently got my truck back, My father and I switched vehicles due to need and distance's being driven. 2005 F350 6.0, 164,000 miles
I couldn't wait to drive it again, I spent hours detailing and cleaning. Well I go to start and noticed it struggled to start, and didnt seem to be idling right. I looked under the hood and it was leaking fuel from the Regulator. I left it parked and never drove it since he last did. I read around on these forums and I bought the blue spring upgrade kit.
Now I notice it shakes at idle a lot more than it used to, pretty bad at times. Then upon driving it shakes even worse upon acceleration attempts, and has very poor throttle response. I have to put it nearly to the floor and even then the acceleration is nothing like it used to be. Most of my trip was highway at 60mph, and anytime it would start climbing a hill it would shake pretty bad with the acceleration. When i let off the gas to slow down before braking it stopped the shaking.
So I read around on here and I went back and used the factory bowl and valve for the regulator, still had the issue. Next I went back and replaced the blue spring with the original, still have the issue.
I just checked the FICM and it is reading between 48-49 during key on, cycle, and cranking.
Batteries are great
Alternator only reads 13.6 at 2k rpm idle, but have not had charging issues.
My father says he never noticed anything wrong with it other than it occasionally missing out. But I don't see how changing the fuel pressure regulator would have caused this. Especially since I tried every combination of oem and aftermarket parts, ensuring that all the connections and parts were installed correctly.
Ford Super Duty (1999-2016) :: 2005 V10 - Poor Throttle Response And Mileage
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 7.3L Power Stroke (1999-2003) :: Intermittent Throttle Response And Poor Fuel Mileage
I have read many different threads regarding the TPS sensor on the pedal and EBPV deletes on the E99 7.3L Powerstrokes. I am trying to troubleshoot some issues with my E99 7.3L. Usually on cool mornings and after not being started for awhile the truck will seem to be stuck in an Idle. This is an intermittent problem that doesn't always happen.
I cleaned the connections to the Tps and the IVS sensor and put them back in. No luck. On another note I am also seeing a reduction in fuel mileage and power like the truck is being restricted. I don't know if these symptoms are related or possibly their own issues. I am troubleshooting and possibly thinking it is the EBPV system that isn't working correctly. Considering doing an EBPV delete with a NON-EBPV Pedestal and Flange.

I have a 2003 Mercedes c230 with low mileage 70000. This was its first season not garaged. About 2wks ago when very cold started abruptly to misfire badly at idle with poor gas mileage and modest loss of power. I got codes on OBD II for multiple cylinder misfires p0301-4 (all 4 cylinders). No other codes. Also the MAF and O2 sensors seems to be giving normal readings, and I cleaned the MAF sensor (didn't take off. cleaned through screen connected to air filter housing). 1 or 2 of the spark plugs seemed fouled as had black oily fuel on them and the O2 sensor voltage readings were consistently close to 0.9v (high meaning reading rich air/fuel right?). Changed all 4 plugs and swapped around ignition coils. Seems a little better but still misfire. O2 sensor voltage reads now consistently around 0.7v and the new plugs are dry but already blackened (indicating rich air/fuel I think).

Title says it all come to a stop, step on throttle nothing, let off and step on it again it goes, does some one have to be killed before Ford knows there's a problem, it's happened to me 3 or 4 times in the last month, dealer checked said there's no codes so nothing wrong. OK I forgot the good info 2014 eco screw 4X4.
View 12 RepliesFord F-150 (2004-2008) :: Spongy / Slow Throttle Response
I am a dedicated Ford truck owner. Both vehicles I have had are both F150's. My first one was a 5.4L v8 03 and my current is a 5.4L v8 06 4x4, seen below.
When I bought the truck it was straight piped. I went ahead and did a GOTTS mod on it. The truck also has the factory tow package. I replaced the spark plugs and engine oil (Amsoil High Mileage). I did a couple basic things like putting in the light bar and replacing the headlight housings. Other than that it it pretty much the same as when I bought it. I cleaned the throttle body and sensors, using the proper cleaners. I ran two cans of SeaFoam through as well.
With my last truck, I 'flushed' the transmission (not a actual flush, but I changed the tranny oil about 7 times in a short period of time). A buddy suggested I do it, as it was a DOT truck and maybe wasn't treated the best. It was a automatic, just like my 06. Would that do any actual good?
I have noticed that truck has a spongy/delayed throttle response. The engine idles normally and there are no codes being thrown. I had a similar issue with my 03 but it had a cable to the pedal and I just had to tighten that up and it was better. Perhaps because of the straight pipe and GOTTS and no tune?

Resetting Throttle Response. I came across this video, bored and just playing around, and tried it on my 2013.......and it works! Turn the ignition key to the run position, then slowly press the accelerator pedal to the floor. Then let the pedal up fast, then turn the ignition off. Do this 3 times, and on the last time, also turn the ignition off. I was amazed that that the lagging pedal response was almost completely gone!

Experiencing sluggish throttle response on the EFI Ecoboost? I have had several incidents where I'm needing to change lanes fast and the response is a dead second or two before the motor catches up to the throttle position. Then, it rockets forward at full throttle to catch up. By that time it's too late to change lanes and I have to be on the brakes hard to keep from rear ending the guy in front of me. I'm coming from a carburetored Toyota Tacoma that was far more responsive (minus the power) then this truck. I never felt hesitant to jump on it and go. Now I feel like my life depends on waiting until I have all day to change lanes, make a left turn or pass a slow moving vehicle on a two lane road. Is this something the dealer can adjust?
View 14 RepliesFord 7.3L Power Stroke (1999-2003) :: Only Idle / No Throttle Response At All
I have a 99 F450 with the 7.3L in it. I brought it home the other day and parked it. Later I went to do something with it and I had no throttle response at all. I checked the wiring going in and coming out of the throttle position sensor. I have approx. 5 volts going in and the voltage sits at about .5 volts and rises as the accelerator is depressed on the outgoing wire. The other switch on the pedal is open and does close when the pedal is depressed, so it seems those are fine. I'm not sure what I'm supposed to have on the 3rd wire that goes to the TPS.
I have a Bully Dog tuner and it shows an exhaust back pressure sensor error and a couple of voltage errors to the accelerator pedal. I read somewhere that someone had an exhaust sensor short out and it starved the accelerator pedal from voltage or something like that but I do have good voltage at the pedal going in and out. I ordered a new sensor and tube.
If the exhaust pressure sensor was shorting out and I unhooked the wires could that make the pedal work if the sensor was the problem or would the accelerator pedal not work at all without that sensor being connected? (The old tube was somewhat plugged up and I saw it had a small rust hole in it)
If it's not the sensor, what else can I check? Where can I check under the hood to see if the wires from the TPS are getting power to where they need to? I assume they go to the computer and that tells the pump or whatever to give more fuel.
Ford 6.0L Power Stroke Diesel :: Truck Went Down To Idle - No Throttle Response
So while driving just now the truck went down to idle and no matter what I did to the gas pedal the throttle would not change. The truck didn't die but would just sit at idle. It was like the gas pedal wasn't connected. About a minute later it surged a little and then I was able to drive like normal.
History- last week while at a red light the engine surged and then almost died. Light changed and I hit the gas....and stayed at idle...then died. Restarted and died two more times and then just drove like normal. Changed fuel filters and and checked fuel pressure. Under boost it was 38-40 psi. Idle it was 45. Cac tube replaced due to cracks.

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?

View 14 RepliesFord 6.0L Power Stroke Diesel :: No Throttle Response In Gears After Injector Install
I just completed installing rebuilt injectors in #2 and #4. for the 2nd time. The first set had failures with those two. After assembly, the engine runs rough which is understandable considering the air introduced. I can run the RPMs up while in neutral or park, however; there is almost no throttle response in drive or reverse. It will barely move and only slightly raises the RPMs. I am unable to drive it to get the air out until this particular issue is solved.
Prior to the tear down for #2 and #4, the throttle response was fine.

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?
View 10 RepliesFord 7.3L Power Stroke (1999-2003) :: No Throttle Response Stepped On Accelerator Pedal
I own a 2000 F250 7.3 Powerstroke 4x4. The only aftermarket engine modification I have is a Tymar intake. The problem I'm having started about 6 months ago in a very erratic fashion. I would pull up to a traffic signal and as the light changed to green, without warning the truck would have no throttle response. The engine was running fine; there was just no response as I stepped on the accelerator pedal. Usually when I put the transmission in neutral, revved the engine a few times, the throttle would come back on line. This happened 4 or 5 times over the summer and then went away completely until today. Today it came back with a vengeance. At one point I had to shut the engine down completely to restore throttle response. It's a bit unnerving when it happens in the middle of a busy intersection. I was told that it may be the throttle position sensor. Does this sound correct and does it need to be replaced?
