You can do both ways....remove or in place... in place get some TB cleaner, high rev and clean, but best to remove, scrub, clean... Idle could also be the IAC needs to be cleaned and along with that the TPS will need to be reset... anyone can do this

Pick up a can of TB Cleaner (NOT Carb Cleaner) at Auto Zone.

Remove the MAF & TB bellows, open the throttle and wipe out the TB bore & blades. Some cotton swabs may help get into tight areas.

Might want to pick up a new set of IAC gaskets, and replace the coolant hose that connects to the front of the TB if they look to be in rough shape.

The IAC is just below the throttle position sensor. I suggest you remove the TB, it will make it easier to remove IAC and to do a full thorough cleaning.
