"eco" and "pwr"

[Jousi]

I believe it is not same problem, economy light just measure vacuum pressure in the manifold and lights the "power" light when vacuum drops, like on the moment when throttle flap opens wide or when engine is strained heavily.
The sensor is on the right side of the engine bay, on the strut tower. There goes one little hose from intake manifold and one wire. If you put the wire straight to ground, if i remember right, the "power" light goes on.
