Adam, if your idle is off try cleaning the IAC valve on the driver side of the upper manifold--looks like a long cylinder attached by two or three bolts. You can use throttle body cleaner or brake cleaner, just be sure to get it all out and let it dry. Next I would invest in some good plug wires. When I got my Jacobs my idle dropped to 600-700 range and became very, very smooth. About $50 with lifetime warranty.
