Joe,
Seems like that is a good reading. You are not running to rich and looks like
you are not having a lean misfire with a high HC reading. With todays cats and
O2 sensors plus all the other stuff usually you get a Zero reading on both.
Took my 99 Dodge Dakota in and all they did was plug in under the dash and said
"Past, $12.50"
I gues I should take the 61 over to a shop and get a HC/CO reading to see how
she is doing.
