Hey guys, i am havin problems with my 7... 86 gx... i start it up and i hear like a hiss sound almost as if it were trying to suck something in.... comming from the bottom of the car..... could this be a vaccuum line ??? my car runs like complete a$$ i could barely make it outta the driveway

 

Yeah, more than likely it is a vacuum leak of some sort. Start the car and let it idle. pop the hood and listen to find it.
