WHen I start the car it will right away jump to 2000 rpm. When I hit the gas it will jump to 3000 rpm and stay pretty much in that area of engine speed. I treid playing with the throttle both by pushing it to increase the speed of the engine and also by pulling on the cable itself to make sure it isnt sticking. Any idea what it could be ?

Intake leak??? No idea where to look though.

Yup, most likely a vacuum leak.

Vacum Leak. If you over torq the manifold this will happen.
Also in the rear of the manifold, close to map sensor there is a vacum hose leading to you a/c panel.
If you put your selector **** to defrost leave it for 15 seconds and place it back to just a/c and this causes to still blow in defrost mod then its leaking from tha hose
Also ASR (traction control) is ran by vacum, its on the driver side of the manifold. There are two vacum hoses there. One has constan vacum and the other only when ASR detects a Low Traction event.

Also if you miss with the Idle Air Control Valve (IAC)or(IACV) and now its not seating correctly, it will cause a simlar effect.
This can be corrected by cleaning the valve and cleaning where it sits

Also some times by descreening the MAF Sensor will cause this to happen
You can fix this by buying a new one.
