Ok this is a vacuum leak of some sort when its showing boost (small like 0.somthing) when Im not even touching the gas right. Just double checking.
you should be pulling like 16-20 in of vaccum at idle
can your gauge read actual vacuum or just boost???
Vacuum is below 0", so he is saying at idle the car should have around -18ish vacuum.
Sell it and get one of these kinds.

They are way better and can help with diagnosis on the motor.
