OK....soooo...

It is not a vaccum leak. It is the sensors. There are 2 sensors on the throttle body. One is the MAP, and i forget what the other is (i have arrows pointing to them in my pic) Coming off of the harness, one connector is longer than the other (you can see in my pic...im holding it with my hand.)

When i had them plugged in the way it seemed to fit right...
which...in my diagram would be Blue toBlue and Green to Green.
The motor would jump up to around 4000, then fall down to about 2000, then would constantly go up and down between 2000 and 3000. I thought it was a vaccum leak causing this.

After spending a while trying to find the 'leak'...i unplugged the sensors. I plugged the Blue into Green, but couldnt plug the Green intoBlue because it would not reach.
After doing this...the motor settled down to 2000 and stayed there. It seemed a little unsteady (maybe because the other sensor wasn't plugged in?) but was not as uncomfortable as before.

Are these 2 supposed to be switched? The harness is caught up under the old manifold brace (which i have yet to remove)...so if i get it free im sure the Green connector will reach the Blue sensor. But before i go and do that i want to make sure this is even what im supposed to do.

An easy way i could have prevented this confusion was by marking the sensors so i knew which one went where...so, i guess this is what i get for disconnecting things without making sure i remember where they go.

...also...what about the other 2 sensors? One is on the IAC and the other is mounted on top of the manifold. It seems like there is really only one way those 2 will reach. I plugged the longer connector into the IAC to see what that would do and the motor settled down to about 1000, but again..seemed a little unsteady. but...there is no way in hell the shorter connector will reach to the top of the manifold.

I hope this description isnt TOO confusing. I tried to explain it as well as i could.

I need help with this ASAP...I need to get the car driveable again by tomorrow night.

THANKS!!
