If you have not already done so, I recommend that you clean the back side of the throttle body and butterfly plate. Good time to install the Billet Technology oil catch can also. http://www.billettechnology.com/#!__page-0_copy1

I cleaned mine at 32K and 56K miles, then installed the oil catch can. Totally fouled with crud both times.
