Help! Catalyst reading incomplete

[LvieiraC5]

Hi Everyone,

I have an 02 Vette and it didn't pass smog due to the cat incomplete. I had the battery die on me a month ago or so and charged it back up. My smog people said to drive my car for 50 to 100 miles and it would reset. I've driven it 1,300 miles and it still is showing incomplete.

My mechanic said maybe it's one of my 02 sensors, so I replaced it.

GM said to drive a certain drive cycle which I've done 5 times now.

Can anyone help me figure out how to get my monitor to read my cat?

Thanks,

What codes are registered?

No codes, just wouldn't pass smog because of an incomplete monitor for the Cat
