o2 sensor
 

Hey guys,


I just picked up an 04 '8. The O2 sensor is gone on it. Is this a huge huge deal to get fixed immediately?

Your car is probably running at a preset limp mode and you should have a check engine light. It's emissions related and is definitely effecting your gas mileage.....I would get a sensor, which sensor is it?

no clue. just said the 02 sensor had just went a couple days ago and mazda gave him a quote of $168 CAN ( i live in canada). just wondering how urgent it is to get fixed.
