Thanks for posting

The pre cats can not set O2 sensor codes, to be a little more specific please submit the exact code numbers you are getting, there are some common problems regarding O2 and A/F sensors on these engines as well as catalytic converter issues.

I also need the engine type information, please check the label under the hood or upload a photo, thanks.
