What kind of car?
Electric/manual choke,etc?? Need info.
Without knowing anything else, I would say to open the hood and take the air cleaner off. Open the throttle full and then let it snap back. Listen for sounds. You will hear the throttle hit a stop, some stop somewhere. This will narrow down where the problem is--leftside, right side,etc. This will tell you where to look for whatever is preventing the throttle from closing.
