Did you replace your lower intake boot recently??
If so, pull the upper boot off and look down inside the lower boot with a flashlight and make sure the lower flap in the lower intake boot did not get caught and is inside the throttle body.
Also you should be able to turn off and restart your car while rolling.
If an automatic, just put the trans in neutral, the the engine off, then restart.
If a manual, do the same but have the clutch pushed in.
