Hello together, has an experience with learning from this control unit (EEC 4)As far as I know this control unit has to be relearned after the battery disconnect, that means it forgets all calibration data??? My problem is that my control unit throws out every time the error mixture too thin, but the candles look good electrode gray and the rest black.I exclude leaks because I bathed the whole intake tract in brake cleaner, as well as the petrol pressure is ok , filters and tank and pump are new.Air mass meter is new, Ignition control unit distributor cap , fingers , cables and candles are also new… Does anyone have any idea yet learn ??? have not driven longer distances yet
