OK no luck so far, maybe some more info.
It's a 91" injected 16v manual, the linkage first pictured has carb servo stamped on it and runs back to this grey control box, the box has 12v power to it and also has one pipe running back to this T piece centre second picture.
If we follow the pipe to right of picture it goes through some type of filter then into a larger pipe into the bottom of the throttle bodys.
If we go left of picture the pipe goes back through the bulkhead and inside the car to the drivers area.
I live in the country and the car is not registered so can't drive to a alfa mechanic, it's not running we anyway but I'm just going out now to get the rotor. Thanks for any help.
