Help Please! Idle!!!!
I've got to get this car to idle higher. Sometimes it's fine in park w/ AC off and it'll idle at about 1000 RPM, once you go into any gear besides park and neutral it drops down to about 500 RPM turn on A/C and it'll drop down to about 400 RPM. Also I was checking around and found this thing to be unplugged? Is there something meant to connect to it? It's getting REALLY annoying and summer will come any day now and with 115oF heat I cannot drive without A/C 
. Guys PLEASE help!!!!!!!!

That "thing" looks pretty important to me. I'm not familiar with the layout of your K-Jet system but that might be the idle air valve which controls the idle speed.

As in control you mean like if it detects the idle is going down it'll speed it up etc? It looks like any other plug on a W124 but I can't find any random cables laying around near it. I'm gonna go look again to make sure.. Grrr this car is pissing me off! lol

All of them!
Look closely as I don't believe your wiring harness fell off. That "thing" is called an idle control valve. Hence it is what the computer adjusts the engine speed with. How long has it been disconnected?

Can anyone please post a pic of this area on your engine so we can see where the plug is coming from?

Well guys, thanks for the help and I found the plug. After looking around I found the exact part laying around, I mean like an extra it was hanging around the engine bay :S plugged in. I took it out and plugged in the idle control valve that was installed and YES it works great now! BUUUUT now the idle will randomly go up to like 3000-4000 RPM when in park or neutral. When I first start it, it starts fine at 1000 RPM but after a while it gradually goes up in RPM's in idle. If I'm driving around it feels like it's pulling me, as in if my brakes go out I'm screwed. I then replaced the current ICV with the extra one that was hanging around in the engine bay and it does the same thing. wtf? THIS CAR HATES ME! LOL

someone disconnected the ICV because it wasn't working properly, ghettoooo, anyways, take your ICV out and clean it. It is probably gunked up. Use some wd40 or some brake cleaner to clean it, then make sure it is lubed. That should do it.

If it's gunked up would that make it go into high RPM's? And as to clean it I just spray wd40 in there?

It could, if this thing gets stuck, it is messing up your air/ fuel mix. spray some wd40 in there move it around and see how well it moves. Should be pretty smooth. It should also be clean bare metal. Look for corrosion etc.

If you would care for every guess in the world I'll be happy to run you around also. So let's see, have you done a search because all answers can be found with the search button on the upper right of the page. Check the air in the tires. Are you too close to power transmission lines, I read that could do strange things including causing brain tumors? (which maybe is my problem) Is your foot on the throttle, removing it should lower the idle it that case? Swapping every part from a known good car might fix it.
Back to my question, how long have you owned this car? (how long has it been disconnected) It controls air (idle air only as the throttle should be completely closed at idle) not fuel. It's controlled by the CIs-E control unit with a ground and the power comes by way of the overvoltage relay. It has to be a severly abused/neglected vehicle to have a sticking idle valve on a m103.
Bottom line, No answers = no answers. I'm sorry it didn't get fixed by plugging it back in, but those plugs don't fall off by themselves. So ask yourself why was it disconnected and maybe you'll be heading somewhere.
Answer some simple questions and we'll try to diagnose you cars ill instead of you just being frustrated.

But I'm not frustrated o_O. And I did search, for adjust, idle, icv and it didn't come up with specific threads. I just asked in my previous post if the ICV is meant to be wide open in the little hose ports, the "out" side seems to be blocked off about 90% is the mechanism meant to freely move?

Yeah , the idle control valve will stick. Also, there are two rubber hoses that get old and nasty from being under the hood for long years. They tend to crack and fall apart.
The best thing is to order a new set of hoses and a valve and replace it all at the same time.
The lower or rearward facing hose is time consuming to get installed correctly without a few choice words. At least it was for me.

.Wanted to thank all you guys for the help and tips,
It's much better than before I rather the high RPM's at park than having 20 horses with the A/C on :P
