Sorry for late reply.. i was busy wid exams!!
i had time today so i checked as u told abt the sensor!
Throttle sensor is Working FINE!
coudnt find the AIR SENSOR, O2 SENSOR, MAP SENSOR! i only found the throttle sensor and it is working Fine(i took it off, the engine check light was on and rpm was behaving strange and wen i put it back on everything was Fine!
kindly Explain in DETAIL where the rest of the sensors are??
As for parts replacement i've only replaced its ORIGINAL FUEL PUMP with a compatible one(bcoz the original stopped working at all)!
mileage is 19K
im the 2nd owner of it.. and as much as i remember it didnt come with the problem!
It has no CNG .. its only on PETROL!
