I'll get one of the site mods to move it for you.
As for your problem, this has been reported a lot. It has to do with a combination of the MAP sensor and/or the idle air control solenoid/valve. Try the "MAP whack". Your MAP sensor is locate on top of your throttle body. Undo the wiring harness, take the rubber end of a screwdriver and firmly tap the top of the sensor several times, put the harness back and see if this helps. If it doesn't then you need to look at the IAC as mentioned above. Also, it won't hurt to reset the ECU. Look at the fuse legend in the driver's footwell. Find the "BACK UP" fuse and take it out for about a minute and put it back in (ignition OFF).
