closed loop fueling is the engine computer using the oxygen sensor input to control the engine fueling, the normal oxygen sensor on most cars are "narrow band" sensors and only know if the fueling is rich or lean by the voltage, anything below around .45V is lean and over .45V to around 1V is rich, to keep the catalyst working efficiently it switches from slightly rich to slightly lean to get a little extra fuel with the little extra oxygen to keep the chemical reaction with the precious metals going on to keep the stuff under control.
That ball thing with one vacuum line is a vacuum canister to hold some vacuum to help some systems work when a low vacuum event happens.
Most flammable sprays will work to help look for a vacuum leak, an unlit but flowing propane torch works too...
