Poor Acceleration When start moving with A/C is On, Also engine go off on motion

What is your question?

(1)My car 136km is having very poor Acceleration while moving with A/c on and go smoothly after a while. But just normal without A/c. (2)Engine tent to go off while on motion either with A/c or without A/c. (3)A/c is blowing normal air not cooling. I have gone to many mechanic i change many suggested parts like spark plug, fuel filter, resistor motor condensor cooling fan, oil/air filter, sensor crankshaft, clean injector, add coolant, replace gas for A/c. Another scan give this codes, p0077, p0198, p0340. Nothing seem to work, i just want to Replace the right parts that is causing these problems Thanks
