Am new to the 6.0 mod game. Have a 05 6-speed that I have been modding. The truck has as I call a dead pedal, meaning on hard acceleration when you first get on it and you get into the throttle nothing happens for a second or two, and then it takes off. Is this normal? How can it be eliminated, and made to be more responsive? The truck is currently running a Quad 160 module and free flow exhaust. It also had this stock, and w/ a superchips tuner.

Well, they all have turbo lag, so you have to separate that factor out. But I know what you mean, and either a bad EGR or EBP sensor can cause that. Have you had them checked?

In the past, the "dead pedal" issue was usually associated to cold engine starts and the period of time it takes the 6.0 to warm up enough to move once in gear. My truck has it bad, even after the reflash. What you are describing seems to be more related to turbo lag, which is the time it takes between applying throttle and the turbo kicking in... People used to complain about it alot to the point that they were blaming it on alot of near miss accidents when turning through intersections, etc... I've read alot of threads from people who have modded with tuners and exhaust
to get the turbo to spool up quicker to which alleviates the "dead pedal"
some...

 

[ralphinnj]

No, there are definitely two issues. One is definitely turbo lag. But that is relatively minor. I've had some instances where completely WOT did nothing but VERY slowly move forward, then slowly rpm's build, then suddenly, it erupts....boost, power, everything. This seems to be worse when the motor is cool. But I can tell you it did not do it at all when it was new. It is either the EBP or EGR. They get fubared and you get dead pedal......

OK All,I just got back from a ford truck service center. I have the same problem.. Last week they changed my EGR and EBP Sensor, and I'm STILL having the same problem.. Anyway, the Tech said it is a throttle plate that is stuck open causing the lack of power issue... Tomorrow I'm bringing back to the dealer and he is going to take care of it...I'll let you all know what the outcome is...

I have this same problem with my truck but it only occurs AFTER towing my 5'er my exhaust gets louder and the turbo doesnt spool like it usually does after sitting over night it goes back to normal Im at a loss?? any help would be great.

 

[dieseljeff]

oldford. That's what is happening to me.. Does your exhaust sound like a BIG BLOCK and you have to floor it to get the RPM's up? After the throttle plate install, I will let you know how it is... The Tech told me he has seen it alot, but not enough for a recall!!!

 

[telestar]

Well, it isn't turbo lag and it is turbo lag. It is the mapping of the engine output to keep the cat EPA happy.
The jpan Claybrooks of the EPA don't want us to suddenly accelerate from a dead stop because that means a rich mixture that contributes to pollution. The pedal is mapped to keep the cat in its happy range. Push as hard as you like it won't accelerate any faster than Mother Ford and the EPA want you to.
That's partially why the 400hp GTO won't accelerate any faster than the 300hp Mustang.
Expect all vehicles to have acceleration rate limiting computer control to keep EPA and socialist meddelers who don't like you to spin the tires at the traffic light, happy.

Thanks telestar, I called my local International dealer who happen to be childhood friends and they pretty much confirmed what you say. My local Ford dealer has advised me against chipping my 6.0 but My friends at the INT/dealership say they have applications kicking out alot more than what ford is doing. I just want about 50-60 HP more than what I have now so I don't think there should be any problems. /ubbthreads/images/graemlins/cool.gif

[/ QUOTE ]EXACTLY!!!!!!!!!!! you are the first one I have found with the same problem but I have no answers yet /ubbthreads/images/graemlins/shrug.gifbut I do like the sound it make /ubbthreads/images/graemlins/smokin.gif but i cant handle the power loss the comes with it

[/ QUOTE ]NO the problem I am experiancing only happens after I tow it will go back to normal after sitting a while I cant get boost untill around 2800 rpm after towing normally it builds after about 8-900 rpm I dont think this has anything to do with epa crap because it goes back to normal after a few hours of sitting

 

[dieseljeff]

Well it's not the throttle plate, EGR, or the EBP. All three were replaced by Ford,I noticed that my tow/haul is not working.... MAYBE? It's been in the shop three times for the samething......ANY Suggestions?

 

[moovet]

Did they replace the EBP sensor connector too, or just the sensor????
I've just found out their is a recall on the connector for 05s.

[dieseljeff]

I don't know, I'll ask tomorrow when it goes back for the 4th time..

 

[oldford]

I think I have the answer!!!! WIRE RUBBING my truck went in for a new trans last week after working flawlessly I had this "dead pedal" feel and the next day the trans wouldnt go into gear it was "dead" they checked it and said cant find i reason it wont work so they put it back in and for the last week it worked great UNTILL I got back from towing and i had this "dead pedal" feel and now the trans is dead again no burnt fluid good operating temps ect but its dead. coincidence I THINK NOT!!! it has to be either a wire or computer problem it is at ford now Ill see what they say in the morning. Just to give a refresher on my "dead pedal" feel the turbo doesnt spool untill around 2800 rpm and the exhuast sounds llike a big block with a huge cam init. I get no check engine light or anything the trans shop said they couldnt pull any trouble codes so it has to be wiring problems right???????? I'm open to any other suggestions /ubbthreads/images/graemlins/shrug.gif /ubbthreads/images/graemlins/shrug.gif /ubbthreads/images/graemlins/shrug.gif

Guys,
I've got the same dead pedal. I had it at Ford last week for the problem, and they said that the ebp sensor was bad, so they replaced it.
The night that I got it back, It continued to do the same thing, so I brought it back in and they replaced the egr. I left on vaction over the 4th and I didn't really notice the problem during the trip. Most of the time was 80-90 on I15 to Utah and back to SoCal. Of course it started acting up as soon as I got back and did some local running around. I haven't taken it back to Ford yet, so if you guys find anything out let me know, and I will post anything that I find.

My 04 has the cold dead pedal feel for the first couple of minutes. It has been reflashed a couple of times. I do not have any mods to the truck. If you floor it from a standing start it bogs and won't accelerate normally until you back off the pedal for a second.

 

[dieseljeff]

Please let me know, This is driving me crazy. I'm going to Oceano Sand dunes next weekend,and I'm sorta scared about pulling the trailer..

 

[moovet]

I experianced this same thing at arround 7k miles, I removed and cleaned my egr and things were somewhat better, I had the latest reflash(may.24th.) and things got even better. Mine was always associated with the first start of the day and did not go away with warm up, but subsequent starts were good..To this day 5k miles latter I still precieve a little better throtle responce on second, third start ups but it is now so slight I wonder if it is just in my head.... I hope this helps any...

I have the same thing going on but only when the engine is hot. It happen at strange times like when you need to cross between trafic or merging onto the highway. It is dead and then kicks in and leaves two black burn outs for twenty feet. My wifes rig is a lot quieter and doesn't do it. I could swear I heard a change in the engine sound one day and it hasn't been the same since. Loader and worse millage. The wife tells me mine is much loader than hers. I found that if you pop the throtle and keep the reves up you can then keep it from doing it. I had a snowmobile that did the same thing and it was due to an over rich condition from idle to off idle. I think this could be similar due to the black cloud when it finnal kicks in. It also acts like my hot rod did when I had a manifold vacume leak. I hope we can figure this out it is driving me crazy.
