No there is not. The idle is controlled 100 percent by the ECM. If it is idling too low then you have a problem that needs to be diagnosed.

You have a vacuum leak.

Just behind the intake is a small port with a hose on it.
The hose came off.
Reach back behind the engine on the right side.
You'll feel a little "nipple" sticking out. That's a vacuum port.
Feel around for the hose. It should be right there. Plug it back into the port.
