Hi.

The plenum was pulled this evening by my friend mechanic(and me as an assistant).



There were no loose connections, so we inspected the vacuum lines for leaks, and now I think the worn parts were detected.

(1)Bad Secondary Port Vacuum Actuator
The actuator of LH cannot hold the vacuum and the link (i.e. secondary valve) close immediately, while the one of RH can hold the vacuum as seen in the picture below and the link stays open.



(2)Bad Secondary Port Control Solenoid
My friend mechanic plugged one hole of the solenoid then connected the other hole to the handheld vacuum pump as seen in the picture, and it can hold no vacuum. The gauge decreases immediately.



This is a quick post. I have to determine what parts to replace.



AND A NEW PROBLEM?


When my friend pulled one hose to the EGR solenoid(?), some particles fall down from inside the hose. It seems that the particle come from a charcoal canister... How do I treat this?



Thank you.
