Wont idle... Car wont idle for anything... drops to about 200rpms... back up to 900... back to 200... cutting off sometimes... oild pressure is right above half... and voltage is right above half as well... wont idle more then 3 durations for the 200 to 900.... I had a cam *in sig* installed and tune was done and its been that way about a month now.. and all of a sudden this happends... car has been runnin fine all night... any ideas?

mine did that for a while after my H/C install... after tuning for a straight week... we finally drilled out the hole in the throttle body to be a little larger then stock... fixed the problem! 
when you get a larger cam or heads, the engine requires more air at idle... with the stock size hole in the throttle body it doesn't allow for enough airflow...
