02 Readiness

[ggenovez]

Hi all,

I have a 2001 Xterra V6. and the worst possible time trying to get the 02 / Catalyst readiness to kick on. I drove all over town at 55 mph, I coasted, I did the 2.5 min warm up then drive 55 for 3 minutes then coast down to 20 then up to 55-60 for 5 minutes and coast back down to 20. Nothing. As far as I know the battery has not been removed for months.

I did see there was P0300 error. Can that be my issue?

Any help would be greatly appreciated.
