HI i know you have probably heard this before but im hopeing you can help me.About 8 months ago my check engine lite came on.So i went to autozone just the other day to get the engine lite tested.HE said both of my o2 sensors are bad.Theres nothing wrong with this truck it runs great like nothing is wrong.I have changed o2 sensor in other vehicles and i know what the vehicles do and like when they go bad but not this truck.SO heres my question if my sensors are bad why is my truck been running great for the past 8 months and its still running great.IT has the 360 mag and its a 1996 sports and it has 87,000 miles on it.I only have put 6,000 miles on it in the last 14 months when i bought it.

ps is there something else i could check to see what else it could be as far as the codes go.What else could be the cause of the o2 sensors code showing up,Thank you.
