I guess you didnt realize that you have an obd1 system and not an obdII. I guess you didnt know that obd1 systems would only throw a MIL after a failure has occured and has no way of monitoring the deterioration of components such as an oxygen sensor, so just because you have no MIL doesnt mean your o2 sensor is fine. And your saying im the type of guy that replaces stuff for fun? Well then I guess your the type of mechanic that see's a DTC and just replaces the sensor. I guess when you see a knock sensor code on a Nissan you change that too? Or an oil pressure circuit fault on a GM... or wait.. im sure you dont know about those because your a little brake and LOF bitch.

Why you even posting a thread on here? I thought you were a mechanic?
