Question throttle lag

OK, so I've been reading a little bit on it and I know the easiest way to do this apparently is to tune it out, but I hate the throttle lag that they put into these things. Now a few people have mentioned a "DIY" way to get rid of the lag and someone here mentioned "retraining" the throttle, but no details have I found. So, does this really work? and if it does how do you do it?

I don't remember the procedure from memory but I believe it's described in the OM.

I think your talking about turning the ignition to the on position (not starting it) and pressing the gas to the floor for 6 seconds?

That will reset the adaptive learning for the throttle but it doesn't help the throttle lag that was there from the factory to begin with. If it's gotten worse, yes that will bring it back to the way it was when you 1st bought it (assuming you bought it new). But to really get rid of it I think a tune is the best option.

Then again, it seems the adaptive learning still functions and guys are reloading their tunes every few weeks to get rid of it again...The difference being that when the people with tunes do it, they are resetting it to the custom tune specs rather than the oem specs.

I didn't buy it new, it's a 2006 model I bought earlier this year. So I really have no idea if it's worse than factory or not... but, I'll give that a shot and try reloading it and see if it doesn't improve it at all. Any little bit better than it is would make me happier. Does this help the lagging downshifts as well? or just the throttle?

Disassemble the throttle pedal and install
a 4-40 screw to stop the pedal return before
it hits the dead spot at the relaxed end of its travel.
Then do a recalibration procedure (its not in the OM, Nuke).
Here is another trickier mod for the gas pedal....

(the search function works extremely well)

This will reset the throttle body settings and give the car a crisper feel. This is not a permanent fix but does help out every so often. Also unplugging you negative battery cable for 15 minutes will reset some settings but is not recommend unless you know what you are doing."
I believe the time to leave the battery cable disconnected is 20 minutes per a previous post by 157db. This resets the adaptive learning.

well, since I usually end up tearing stuff apart to see how it works anyway I may very well do that DIY mech. mod. That sounds like something I'd be lookin to do. Maybe I'll have time to do it tomorrow... Thanks y'all!

Here's the one I do. Found it in a post way back when...
Looks similar to the one 157db cut and pasted from Nukes post.
1. Turn the ignition on. Do not start car.
2. Wait for dash lights that will go off to go off. (45 seconds)
3. Slowly depress gas pedal all the way. (Hold for 5 seconds)
4. With pedal depressed, turn key off, release gas pedal slowly.
5. Wait 30 seconds. Start car.
Works for me....

157 is right, there is nothing in the OM about resetting the throttle response. I think it might be just another internet myth. Not sure how the 4-40 screw would work but it sounds interesting.

I wasn't sure if the procedure came from the OM or not and now I stand corrected.

It DOES work.
