I had the exhaust resonator replaced and the check engine light came on shortly afterwards. I replaced the o2 sensor on the manifold and the o2 sensor is still showing incomplete on the mechanics engine scanner. Should I replace The o2 sensor after the converter?

What is the code and what engine size? You may have replaced the wrong one.

It's a 3.8L Supercharge. No code is showing. It's just telling him that the 02 sensor and evap is Inc. I downloaded the info you have already emailed me and he wouldn't even look at. I'm frustrated and confused. I can't figure this problem out

Is this the one with the monitor problem? I thought that it was explained to you if you can't get satisfaction at your shop then go to another place. That may be a problem with the ecm or a bunch of other things, air leaks will also set that code since you've had the resonator replaced it may have one.
