wont idle unless i wiggle this sensor ...
it will start, idle for 3 seconds, then stall ...
unless i stand there and quickly wiggle this sensor ...
if i need a new one, where can it be bought?

it looks like the TPS throttle position sensor
but could be the IAC idle air control
clean the conections first and see if that works

x2 on TPS and clean the connection. While you're at it goop some dielectric grease in the connector too.

i apologize if my original post was unclear. this car is a 2.5 and has throttle body injection. the sensor pictured connects to the throttle body via 2 torx screws and has a little arm on the opposite side of the connector. i BELIEVE it could be the throttle position sensor.
By wiggle i also meant the little arm that gets moved when the throttle moves. NOT THE CONNECTOR. if i unplug the connection it wont barely start at all, so the connection is good.
if i wiggle the little arm on it quickly its almost a steady idle, pressing and holding it down doesnt change anything, and leaving it to work with the throttle just leads to an eventual stall.
hope that helps. PLEASE ASK QUESTIONS IF IM UNCLEAR!
THANK YOU!!!

It is the TPS then. Not sure what the actual value is but you should be able to find it in a service manual. Manual will also tell you how to check it using an ohmmeter assuming its adjustable. If its not adjustable then replace it. I would try to check it first regardless though.

Did you adjust the new one? You can't just put it in there and it automatically works. It needs to be adjusted correctly. This site shows you the adjustment procedure. http://autorepair.about.com/library/faqs/bl232i.htm
I did it, and after my jeep would idle too low, and now It runs like seabiscuit.
Its not a hard job, but can be frustrating getting the damn voltmeter needles into the wires.
