before replacing the O2 sensor, have your car scanned first. ang defective o2 sensor gives out an error code and check engine light. unless nag check engine, i doubt sira na yan.
malaking gastos din yan at kung hindi sira, sayang pera. no refunds.
personally, nung nag ganyan ang gen 1 at gen 2 ko, bumili lang ako ng throttle body cleaner pati contact cleaner.
spray at linis ng throttle body using tb cleaner. spray din ng contact cleaner sa MAF sensor. tanggal battery din para reset ECU.
total cost, 500 pesos. result, di na mababa idling ko.![]()
