port is clean, Im seeing a slight 1-2mm rise in the pintle at idle. Whats up with the vacuum amplifier, what does it do? green is EGR vacuum, yellow is manifold vacuum, orange is bernoulli (velocity) vacuum? I assume the orange is the 'trigger' to open the manifold vacuum up to the EGR via the amplifier? Im lost.......
