Just bought a 2001 Maxima and it threw a code. looking through the manual, it says to use premium gas... well, i didn't think it needed premium since it doesn't say it inside the gas cover or the dash, so it was filled with 87 octane...
well, i had the code pulled, and it's P0420 which has something to do with the cat... (low bank 1???).
Now my question is, do you think the weak gas caused this or do I need to to take it to the nissan dealer and get charged $85 if it isn't a faulty cat or O2 sensor?
Should I disconnect the battery and discharge the computer and just see if it comes back? The BIG PROBLEM with this is emissions is due this week to get my tags renewed... Grrr... thought???
