Not really a different problem...this goes undetected for a lot of these motors for a long time...what happens is it gets fixed eventually but, the whole time it was leaking it has completely screwed up the O2 sensors...

I know the problem was going on with the previous owner and I let it go for at least a year or so and as soon as I corrected it I actually didn't change any sensors and everything seems fine but again what may work for one person may not for another..
