[QUOTE="dunkdie, post: 28410, member: 23038"] Hi all,yesterday I got into a situation where my car idled erratically after I started the engine (hot start). Upon OBD reading at my mechanic I was told that the pre-cat O2 sensor is faulty. But after manual throttle reset the engine idle normally even though the check engine light is still on.So the mechanic told me that he'll reset the fault (meaning no check engine light anymore) and I were to drive my car until the same problem occurs. Only then if the OBD reading shows the same fault (O2 sensor) then he'll recommend me to change it.So I was just wondering if it is advisable to go for the used or aftermarket ones instead of the OEMs?I think the O2 Sensor is indeed the culprit since I got other symptoms as well (poor acceleration, high FC - 11.5l/100km for a 2.0) Thanks for reading and any comment is appreciated.
