Default Fixing Throttle Response

I think I read it here, but not sure....


There was a thread I read, I think here, about turning your ignition key to "on" and then pushing down on the throttle slowly and then quick release. Do this several times and it temporarily gives you quicker throttle response. (Or something like that)


Not sure if I read it here or somewhere else. Hell maybe I dreamt it Either way, anybody have any clue to what I am ranting about???

You may be thinking of someone talking about tuning the vehicle. When you get a tuner with custom or canned tunes (which will change your throttle response and many other things), you turn the key to the "on" position to download the tunes.

no, there is definitely something like that floating around...
placebo effect or not, I dont know... I did it once (I think I did it right) and noticed nothing.

Found this:
"Turn the key to the on position but DON'T start the engine. Now press the gas peddle to the floor SLOWLY and let it come up/back as fast as you can, turn key to the off position. Now do this two more times."

https://www.f150forum.com/f4/throttle...s-5-4-a-71539/

Here is another method as well

"I got mine to 108%. Wide open throttle started being displayed at around 89% and I still had throttle left. On the floor, the pid reads 108%.
I took the assembly out to try the mustang mod, saw that it's a different system on the F150, so had to put it back in after doing nothing. But when I went to reinstall, I saw that the 2 bottom mounting holes are oblonged just a little. I put in the top bolt, and I held the the bottom of the pedal assembly as far forward as possible,and tightened the bottom bolts. turned the key on, waited for the lights and did the reset. Like I said it went from a top reading of 87% to 108%, and the difference from a dead stop take off now is amazing."

Thanx. I thought I saw it here. Will try it anyway. Nothing to loose.


And my success with searching for anything here has been much less than successful, to say the least. Maybe its the way I am searching??


But I agree 1000%, Google IS your friend.

yes, forget the search function here and go straight to google with "site:f150forum.com" before whatever you're searching.

anyway, let us know if it works for you!

I most certainly will.


Now I will have to modify my search method. Maybe I will get better search response as well as throttle response...

I'm pretty sure that fix is temporary.

It will work for a week or two but it does help. The drive by wire still sucks!

Default Fixing Throttle Response

In the 04-08 section, that got brought up daily, trying to eliminate the flat spot on acceleration, with the 5.4 w/4speed.

When I first stumbled on this, I didn't look at what engine/year it was for. Just saw it by chance.


Then when looking, I couldn't find it. Now will have to give it a go. I am more curious than anything else. Don't even know if it would do anything, since I drive an ECO.


Anyway, I am doing a 1500km trip this weekend. Good opportunity to see if it doe anything for me.
