i cant see any vaccum lines that arent connected, i am single turbo so there is only a couple under there and i can see pretty easily under it...when i lifted the UIM up,thats all i did was lift it up with the throttle body and elbow still connected just to see under it, i didnt disconnect or remove any plugs, or even pull it more than a couple inches up...
other than that, the only other symptoms include the following...

~~

okay that whinning noise i described is more of a piercing high pitched whistling, and it sounds like something is about to explode... its really loud.

perhaps the alternator freakin out? gasket leaking? or perhaps something im overlooking

~~

okay big update...started the car and left it on...

first it hits 2500 rpms...its all breakin up but it stays
then about 15 seconds later it starts to pulse...dropping down to 2000 and jumping back up to 2500, about once a second.
then about another 15 seconds later it was dropping all the way to 1500 and back up to 2500, again about once a second.

could a bad gasket cause ALL this trouble?! that was my friends suggestion but i need more opinnions.


you can see the progression of the thread from me being pissed cause i hit my head up to the point i am at now trying to diagnose the problem here
