high idle on 2003 Mitsubishi Lancer

my car seems to idle very high, sometimes i have to put alot of pressure on the brake to hold the car.
can the cause be a vacumme hose problem?

A sticking throttle cable, faulty idle air control motor (IAC) located under the throttle butterfly housing, a vacuum leak that the is compensating for could also cause a high idle speed.
