Help with Vaccumn Leak
 

I have a 1986 Nissan 300 ZX 2+2 Non Turbo and am having a vacumn leak problem I think. When I accelarate the air quits blowing. When I cruise the air starts blowing again. I can't find a vacumn line schematic for the car. I was told there is a vacumn canister on the car but can't locate it and if it is bad the Nissan dealer doesn't carry it anymore. Any help would be greatly appreciated and please excuse the spelling. Its been a long time since I was in school. Thanks. Bob
