I think my catalytic converter is bad?
Please look at my excel data.
I read and watched on Youtube that O2 Bank 1 Sensor 1 should fluctuate between 0.00V and 0.90V
O2 Bank 1 Sensor 2 should be stable somewhere around 0.45V the entire time.
For those that don't know, Sensor 1 is before the Cat, and Sensor 2 is after the Cat.
I used Scan Tools USB device and OBDwiz software to record the data.
(Sorry, fixed link)
BTW, my engine is leaking somewhere either from the back or from the oil pan.
Haven't been able to find out the problem yet.
