vac leak ... check the bolts at the intake mani, the hose behind that intake mani that runs to the brake booster (which is behing the battery) and the small line that hooks up to the same piece on the brake booster ... it's common for those 2 hoses to come loose which will not only cause a vac leak, but will leave you with no brakes if the hose(s) were to pop off

if all of the above checks out, then get a spray bottle filled with water & start spraying around the intake mani, throttle body, etc. while the car is running ... if the car starts to bog then you have found your leak
