Hello,
Took my 99 Sierra to have the emissions checked and it failed. I forgot that I had installed a new battery which showed the OBDII "not ready". I have driven it a couple hundred miles and also performed the GM Drive Cycle but it still shows as CAT NOT READY. Here in Georgia ALL systems must be ready unlike states like Texas where you can have one or two not ready and still pass. Any idea what I should do? keep driving and put more miles on it? How long before it might reset to ready? Thanks for any help.
Mike
