good evening, i'd need some help with the 2000i.e. engine of my 84 coupé. on the foto you can see a vacuum port 'C', which i closed temporarely with a piece of hose and a screw. it was open and the engine ran much to lean. can anybody tell me what has to be connected there? unfortunately i can't find any lonely and disconnected hose in the whole engine compartment... and secondy: is the T-connection 'B' correct? hose 'A' is coming from the magnetimarelli ignition box at the fender. i'm greatful for every hint! thank you very much!
