My 99 Deville is throwing the P0741 code. I cleared the code and took it to be tested and I was rejected because the OBD was not ready. How far do I have to drive it or let it idle before the OBD is ready? They told me to drive it for a couple of weeks or take it to a service repair facility to have it checked out. Any soggestions?
Thanks in advance,
Bill.
