My car has been idling in N and D bouncing between 500 & 750rpm.

Just noticed the spring on this valve has broken so isn't attached anymore.

Does anyone know what it is? or the part #. Looks like it is attached to a map sensor.

hard to find info on GDI's.

What engine is that ?????

What engine is that ?????
Werd. Mitsubishi Diamante GDI 24v DOHC by the sounds of things.

Exactly that 6G72 GDI. 3L V6

Looks like the actuator for the dual plane inlet manifold to me.
