Default Engine idle and sputtering problems

Hello, so this mourning i go to take my car out to go get some breakfast(93 eg sedan d16y7 no mods that i know of) and i have a pull out little ecu chip thing(Its the locktronics key chip, i assume most know what it is) and when i went to turn the car over the first time it cranked started went up to about 1500rpm really fast then died out. i Took on the key put it back in and it started right up but idles at 1k EXACTLY on the line. I then went and got breakfast and on my way home stopped at the store and the car sat for maybe 10 mins then it did the EXACT same thing, got home and let it sit for 20 mins and can't get it to mimic the same thing again. I believe it has to sit for about and hour or so and it does this. Anyone have any ideas on why it would do this? I know i have a weak *** battery in it but i charged it for about an hour and half before i went and it has nothing to do with the battery. Any ideas or thoughts on what this can be? If it helps(I KNOW for a fact it has nothing to do with this lol) the CV Joints are broke, idk if that leads to something else breaks and eventually leading to an engine problem(Never heard of anything like that but would just like to through that out there lol)

Any thread or posts about where it's located and how to clean it? Ironically that was the FIRST thing that came to my mind but i've never messed with them, cleaned them or even had to bother with them lol

Is this the IACV?

Also does the idle seeming normal? This is after 20 mins or so give or take of sitting. This is what it does AFTER it spurrs out and dies. When i let it set for a few hours i'll take a video of it when it dies if needed.

Also what would cause this leak? Not sure if it's a leak or something that is normal. This is ALL the way to the right of the valve cover next to the last spark plug wire

This doesn't seem to be an idle problem to me. Unless I missed something, the problem is that the engine stalls when it is running at 1500 rpm, right?

This shows the location of the Y7 IACV:

I added 2 videos and a picture to my last post. Heres a Gyazo screen shot of the picture that talks about a leak. No idea what the leak is from or what caused it. I never really check out the engine because i rarely drive the car. But when my dad leaves it come i try to work on ANYTHING i can think of on the car so when i get both my cars i'm a little more experienced

http://gyazo.com/61b4d8a8c92d41ab797b0becbfb7b26a

Also it's not that it stalls "Because it shoots to 1500" it always shoots to 150 when its first started then idles down to 1000. If i let this car sit for a 2-3 hours and try and start it the first start will die out and second one will runs REALLY bad untill i get going.

A high idle for a cold engine is normal. As the Y7 engine warms, the idle speed will drop, eventually to 700 rpm or so, if there is no electrical or mechanical load. The idle speed of a warmed up Y7 with an electrical or mechanical load should be about 850 or so.

So if i turned over the motor and start it around how long should it take until its at 800 or so? Cause it sits at 1k for awhile

You did say it idled at 1500 then died? or does it idle from 1500 down to a more normal operating idle?

In general, idle speeds are only interpretable when the engine is fully warmed up. Use the temp gauge reading in the cluster to determine this. When fully warmed up, the idle speed of your Y7 should be 670 rpm without ANY mechanical or electrical loads. If you turn on your headlights, the idle speed should rise to about 800 rpm.

Here since it hasn't been sitting for it to do it right now i'll explain it in detail

I get in my car and put in the key then my Locktronics Key chip in

I hold in the clutch and turn the key over and it cranks a couple times(Like normal) then turns on for not even a 2 secs then dies. I turn it over again and it starts right up but idles REALLY hard like it's about to die out. Almost like if you where going WAY to slow in first gears without engaging the clutch so it almost buckles then dies. It has that feeling then i just give it some gas(2500-2k rpm) then put it in reverse and leave.

On a y7 when should the car be warmed up? Like hot warm or cold should it be? Right in the middle, a little less then middle a little higher? ect.

That lights been on since we got it lol. How do i "Pull the code"? It not that i'm "Uneducated" about hondas there's just something things i know and some things i don't and more than thankful for any help.

I only used that term because when my dad called me to check the car that's what he said. So i assumed that was a more detailed way of putting it.

I think he means sputtering, so the car is dying when cold, but not once warm?

Fully warmed up = just below the halfway mark on the cluster temp gauge

Those are leaks from the rubber seals on the valve cover bolts. Retorque the bolts to spec or replace the seals.
