i failed the first time...nox was very low, co was average and HC i failed at 70 which i needed a 64 to pass. i was pissed.
luckily i saw how my nox was low so i had room to advance my timing resulting in a hotter burn resulting in reduction of HC and Co.
was i lucky with 6 degrees of advancement it brought down to a 64 exactly and i passed.
i guess in two years if i have the civic still ill have get me a new cat which i was trying to avoid.
im a happy camper!!
