Is this just my imagination? Regardless, I'm going to order a new AC DELCO from GM PARTS DIRECT next week.
I'm probably the only lasting Bosch O2 user!
My 92 SE runs great with it. It might not for too much longer since I added a 180 T-Stat & Custom CAI to it though now.
I figured it had to do with engine operating temperature & the resulting exhaust gases temperature that made them fail. I believe the Bosch like the higher temperatures.
