6 - EGR valve
9 - Anti-shudder valve
13 - Lower section of intake manifold (with shift rod)
17 - Vacuum actuator
19 - Intake Manifold Runner Control Valve (N316)
This is the first I'm hearing of this and this explains what the vacuum actuator is for that can be seen on the passenger's side of the engine. I know the one on the driver's side is for the bypass valve for the EGR cooler.
Anyone seen or heard of this before??
