you need to plug a vac line from the intake manifold to the megasquirt

Yea I know that, that's obvious but it's not changing just stays there unless somewhere between there is a cut or something between the connection to the megasquirt to the intake

You need to figure out what is going wrong with your vacuum line from the intake manifold to the MS.
