I am having a surging idle and was going to check and see if I have a vacuum leak anywhere. How would I go about checking over everything?

On my friends DSM the throttle body bypass/coolant mod made him have a surging idle. Once he put it back to stock it didnt surge anymore.

listen to see if you can hear one. Or you can use a can of carb cleaner spray w/ the little hose the can comes w/ attached. Spray it around areas that support vacume, if there is a leak the idle will increase and or smooth out momentarilly.
