I went with the aerisol can of the seafoam and the next day my emgine light comes one and I have a oxygen sensor code for P0138 and P0139! well I guess some one was right about it taking out O2 sensors. I would imagine that it was already on its way.

 

may just be a coincidence, what kinda mileage are you at ? Mine started going bad around 90K miles.

 

110,000 miles on it. i guess it is time though. when have others had to change them out? do most people use oem Nissan parts?

 

One of mine is out too, just found it Tuesday. Anyone know how much they are from Dave B?

 

hmm..i should start looking out for my 02 sensors too..i'm getting close to 90k...

wanaMax, do you go to u of i? I noticed that you're in the Champaign area...

 

The '02 I just bought had the 02 sensors replaced at 54k miles, just 1k miles before I bought it.
