“Why Is My Hyundai Santro Showing Poor Fuel Average — Is the MAP Sensor o r O2 Sensor Faulty?”

My Santro’s fuel average has suddenly ped, and the car feels heavy on acceleration. A few mechanics told me the MAP sensor o r oxygen sensor might be giving wrong readings, which is common in old Santros in Pakistan. There is no check-engine light, but the performance is bad. How do I confirm whether the MAP sensor, O2 sensor, o r something else is causing this issue?
