“Hyundai Santro Idling Up and Down — IAC Sensor Issue o r Throttle Body Problem?”

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?
