My idle on my 2001 ford explorer sport trak is....mmm not idling basically.
The battery got ground down pretty good and I cnahged it, but I think the
idle issue was there before hand.
I changed the battery, nice and fresh, but I cant get it to run unless I
press the peddle down about 1/4 way.

Do I need to reset the ECU?, how?

I ahve the battery disconnected right now.

You've already reset the ECU.

Next step:  check the ECU for error codes and maybe check for vacuum leaks.

I also am looking at this IAC article.

 Try cleaning the throttle body first. You already reset the ECU by
disconnecting the battery, which is likely the cause of your problem.

No
Find the vacuum leak.

fyi, I have taken it in for the intake manifold gasket crapola some time
ago. A specific error was present for it to be that.
I'll get some codes read tomorrow and report back to ya'll.

Last time I checked, intake manifold gaskets were made of some kind of rubber.
Crap is a terrible materials choice;  tends to dry out and become brittle.

yeah that was a recall item I missed by like a year so I had to pay for the
repair at the dealer.
I'll be getting the codes later tongiht and we'll see what else is
happening, but I sure hope its not that intake again.

There's a hose in the back that likes to split.

It is kind of important to know whether the idle issue was there
before you unhooked the battery.  If it was then, as others suggested,
I would look for a vacuum leak and check the idle air control.

If the truck did idle before the battery was changed then I would
drive it around a bit to let the computer learn how to make it idle
again.  It can take it a little while to re-learn.  You may still have
a problem that is causing the truck to not idle with a "default" data
set in the computer but it should learn to idle as well as it did
before until you can diagnose and repair that problem.

Also note that if you have the battery disconnected any codes that
were there are most likely gone now.  Hook that battery up and drive
it for a while before trying to have the codes read.

1. Vacuum leak

2. Throttle position sensor bad

I would be using a multimeter to verify the battery was getting a
charge.  On a lot of modern vehicles, if the battery isn't getting a
full charge, they won't idle right... before they won't run any more.

ok,
I did the whole battery reset thing while the engine was hot (I drove with
two feet)
and it is now idling.

thanks all.

I WILL return the favor.
