vacuum leak/sputtering problem

[matt38111]

Hey guys i have a 1990 nissan 300zx with a 94 engine and i am having a few issues and would like some info if possible it would be greatly appreciated. well recently while changing my spark plugs i noticed while i rev it up that it makes a hissing noise, now i assume that it is a vacuum leak but im not very mechanically inclined so does anyone know of any places where it might be coming from. also when i accelerate the car sputters and it greatly affects my acceleration which i think is because of my vacuum leak but im not sure. any help would be greatly appreciated thanks.

search "300zx online manual" in google, find the vacuum diagram in there and have fun, get some Excedrin before you start and some Neosporin too.

I'd invest in some mechanics gloves, they will save the skin on your hands.

i bought $800 worth of tools, but gloves would of been a great $15. casue after 2 years, my hands have 3-4 deep scars that aren't going to heal.
