What are these vac leaks??? Everyone is talking about them and I have no idea what they are. I assume it has somthing to do with the intake but I could be very wrong. Anyone care to explain?

Vacuum hose leak. upon drawing air into the intake it creates a vacuum that the Z uses for many different things. infact alot of problems with the Z engine and heater/AC most people will tell you to look for a vac leak.

turn your car on and warm it up. after its warm just let it idle and listen very carefully to the tone. if it purrs smoothly and evenly and there is no change in tone, you probably don't have a vacuum leak. If you do, you will notice the engine speed varies somewhat (look at the tach too). the more it varies, the larger the leak. If you take a look at the whole intake system from the filter to the manifold, you will see several hoses coming out between the AFM and the lower intake manifold. these are mostly all vacuum lines. listen carefully for hisses coming from them at both ends of the vacuum line, or you can use soapy water to detect leaks as well. as the hoses get old, they can split at the end or the clamps can come loose letting air into the system and altering the engine vacuum, which can have significant impacts on gas mileage and power.
