I lost my air filter during the week, but I only realize it during the weekend. During the week the engine was working fine, but yesterday it start operate at an incredibly high rpm at park (2000-1500rpm).

Could be vacuum leaks, dirty idle air control valve and an out range throttle position sensor.

Yes you could but you're straining the drivetrain components and again you're burning fuel when its not necessary
