From what I know your 4G93 engine is the first generation of 4G93 for Proton and it is the more powerful version compared to the later 4G93 installed in Proton.More power but bad in terms of emission control maybe that is why Proton changed to a lesser power, more eco friendly engine in the later version.So your version has no catalytic converter and no O2 sensor.
