That's normal it should be around 18-22 inches of Hg at idle

Re: (stinker504)

why in the hayanes it says under throttle body check.

2. start engine and warm it to its normal operating temperature(wait until the cooling fan comes on twice). Verify the guage indicates no vacuum.

3. Open the throttle slightly from idle and verify that the guage indicates vacuum. If the guage indicates no vacuum, check the port to make sure it is not clogged. Clean it with carburetor cleaner if necessary.

GOD DAMN UNRELIABLE HAYNES EH!!!
