Might be multiple problems, start with finding vacuum leaks.

See these links:

Cheap fluid transfer pump from your local auto parts store or Amazon.

A few rubber gloves, rubber bands and some cheap mini cigars from our local gas station or convenience store.

Also get a good, bright LED flashlight to locate the escaping smoke. Look deep in the engine compartment and under the engine if needed. Do not forget the dipstick guide tube and the lower CCV oil return line. These areas may be hard to see from above in the engine compartment.

If you were at the CCV, you may have forgotten to plug something back in, I had a similar problem, it was a plug that goes into that box with about 6 wires coming out of it in front of the CCV.
I forgot about it because it sort of plugs into the box from underneath. Sounds like could be the idle control valve as well, check that its securely in the rubber boot and all hoses are back on properly and everything plugged in
