After reading all the posts I find anywhere on this, I am still confused about what should be hapening with these parts, complicated more by what the parts are called at diferent times.
Can anyone clarify what does what?
My understanding is that the EGR is actually a motor operated electrically by the ECU, the two solenoids by the battery - one controls the actuator and through that a flap that opens and closes the flow of air from the connecting pipe from the intercooler, into the manifold and engine - not too sure what this flap is for, any Ideas? This flap flutters and when the problem with lack of throttle occurs this is closed
cant remember what the oter one does.
Can anyone help with how this all works?
I have removed the EGR motor, cleaned all the muck from around the valve portion and inside the manifold.
Which part is it that I should be focusing on, the EGR Motor/Valve connected to the manifold or the vacuum solenoids, by the battery?
