The only tool you need to remove the air intake hose from the throttle body is a phillips head screw driver to loosen the clamp at the throttle body.

While you have the intake hose removed, get an old toothbrush and some throttle body cleaner. Clean both sides of the throttle plate and the throttle bore.

I would check for error codes anyway. See the How to get CEL codes thread in the DIY section.
