Hey just wondering is there a way to check the vaccum pressure and check for leaks because I think I may have a vacuum leak somewhere but I cant seem to find it?

if you have an undisclosed vac leak try spraying some integral parts of the vac system with carb cleaner. the motor idle should race when you find it. better done on a cold motor before it gets too hot.
