I have just been looking around the net some today and have noticed that all of these gauges that I've seen, have a negative vacuum when the car is idling. Mine is right at 0 when at idle or running low rpms. What could be having my gauge at 0? What could I do to fix this? I am rather perplexed at the moment... please help me. Thank you in advance.

1. Your gauge is hooked up wrong.
2. Your gauge is broken.

Chances are it is #1. Tap the hose that comes out of the back of the plenum. If you are looking at the plenum from the front of the car, it will be a hose on the back left, right next (and behind) to the throttle body... Can't miss it.
