sorry to bump an old thread guys
ive got a 2005 3.0r sedan
but yeah my car was feeling sluggish and fuel consump went up from 11 to 13 (its tuned btw)
brought it into the mechanic and was diagnosed as a "failing 02 sensor"
it did not produce any error codes yet and the CEL is not on
they said they couldnt diagnose which o2 sensor it was (since there's 4 apparently)
they said i can either repalce all 4 (which doesnt sound logical to me) or wait till it produces an error code
my question is:
- is there a way to tell which sensor is failing if the code isnt produced yet?
i dont want to drive around with a sluggish car
- will it damage my car in any way if i keep driving along like this?
thanks guys!
really appreciate it
jon
