Anyone know what the idle vacuum for the 3.8 is? I'm seeing about 8 inches of Hg and I'm thinking that is really low.

Re: Normal vacuum numbers for the 3.8?
should be 19 mm hg steady. should drop when you give it gas and when you snap the throttle closed it should bounce up past 19, then come back and settle at 19 again. make sure you got it on there securely otherwise you got a monsterous vac leak.2000 3.8L Camaro A4 Pewter Y87<br />K&N Filter, SLP Ram Air kit, Eibach Pro Kit, Flowmaster 80 series, Silverstars, NGK plugs and MSD Super Conductor Wires, Electric Water Pump -
