Any suggestions on this error code. Just spent $360.00 on O2 and still get code.

You paid $360 for an o2 sensor?!?! Which one was replaced, the front or the back? Is the same code coming back as before? Was the code cleared the first time after the new sensor was installed?

The 360 was installed. The O2 was the front(255.95). Yes the code was cleared. I have been told by a Volvo repair shop that maybe manifold problems gasket @turbo or head. I did just have cat replaced @muffler shop was only $149.00, code showed up following week, and repair shop said this code po133b was slow o2.

A slow o2 code is not thrown due to a faulty manifold gasket . The only thing that will cause that code is a faulty o2 sensor. Take it back to them and tell them to install another one. The cat has nothing to do with the front o2 sensor. Also, you let them charge $100 to install something that can be done in 10 minutes with a 22 mm wrench and a screwdriver? And o2 sensors can be bought for $160 from FCP Groton.

Seriously, you might want to start looking for another place to have your car worked on. To me, it sounds like they're ripping you off like crazy.
