now that i know i need some 02 sensors , any suggestions of what brand? where to buy them?

 

I don't know what anyone else is using, but I use AC Delco direct replacements. I have not had any luck with the Bosch from Kragen. I always end up with the Delco's.

Part #AFS75 or GM part #25312184 for the front and ASF97 or #25312196 for the rear.
I have been buying from www.gmpartsdirect.com but there are other places out there.

One more thing, Shoebox's website is one of your best friends. http://shbox.com/1/4th_gen_tech1.html
