I need a vacuum line diagram fo a 1996 Chevy Lumina, 3.1. One line that is not connected to anything, is located at the top of the engine.


Sorry I don't have the diagram, but I do have a diagram of the engine and component locations. Your vacuum system is fairly simple. You have a MAP sensor attached to the air cleaner. I have pasted a picture below. It has one electrical connector and one vacuum hose that goes to the intake manifold or the throttle body.
Behind the right headlight is your evap canister. This will have a hose or line running to the fuel tank. Then it will have another hose going to the purge valve. The purge valve should be close by and it has a connector plus another hose that goes to the intake manifold.
Then you have the PCV hose that goes from the PCV valve in the valve cover to the air cleaner or intake manifold. I think yours just has a hose from the air cleaner and the rest is internal.
There is one more vacuum hose, and that is the bog one that goes from the intake manifold (or throttle body--looks to me like there are a couple of vacuum ports on the back side of the throttle body, and there may be a "T" on one of the hoses) to the brake booster. It this one was off, the engine would not run, as the vacuum draw is large. Please let me know if you cannot figure it out from these instructions and provide a picture, if you can.

Ford focus, 2000 zx3 code p0455


your engine code means "big leak" in the evap control system, this system has alot of pieces, but you are looking for a vacuum leak most probably, look at your vacuum hoses, and refer to the vacuum diagram stuck under your hood for routing, see if you have a bad hose, or disconnected hose some where. these are small vacuum hoses that attach to the purge valve, air filter housing, and charcoal cannister. let me know what you find.

Sucking noise from engine compartment. I'm guessing vacuum leak, but need pointed in the right direction. Anyone know of something typical?


There is no typical. Try this, even though if anyone sees you they will laugh: Take a piece of hose, Heater hose, garden hose etc. Put one end to your ear and "scan" the engine while running with the other end. It will help ;you "dial in" the location of the leak. Then, fix it!

This is by design, there is a WOT [wide open throttle] cut out that cuts your ac off to be certain you have full horsepower for passing.
