And the best way to find those leaks is to smoke the system. The smokers were expensive when the shop I worked in bought one, but well worth the investment for a commercial shop. Today's cars use less vacuum controls, so the price has probably gone up on them. A shop that does emission control work should have one you can bribe them to use or borrow. It utilizes baby oil and very low pressure so it doesn't overpressurize the vacuum system. Very useful for finding intake system leaks also, but don't let it coat a MAF sensor unless you clean the sensor BEFORE you energize it.
