Default 06 DTS Bank 1 o2 sensor siezed

So here we go...new guy in dire need of help on this one. I have an 06 DTS that has a seized o2 sensor. And...its the firewall side. I'm gettin old and fat and reaching that booger is really hard so for Xmas my wife said "have the shop fix it."

They choked. They don't have the gear or know-how to get at it or pull the manifold to do a bench service on it. Me? I've done hag jobs before but this one looks really special.

Has anybody got any shop manuals or experience doing this job that they can shoot my way? I can't afford the dealership--I've seen drug habits cheaper then my local shop--and I need to get back on the road.

Any help would be golden.
Thanks for looking.

I'd agree with your wife, bite the bullet and take it to the dealer. Emission warranty is 8 years, when did car go in service.
