Follow the vacuum lines, see where they go.

Thanks sixto,

I you are right, the ECU and gauge temperature sensor are more on the top of the engine as you say on the same line.
What is EGR?

The vacuum lines go , one to the idle control valve, the other on ignition unit, if I am right.

My car has irregular, unstable idle when hot temperature. Does this device have an iinfluence on the idle? ECU temp sensor is new,
I have posted a topic "loss of power while running" any suggestions?
