Any ideas out there, I was pulling a PO158 code, which I replaced the front driver side O2 sensor, then right after I started the engine again I got another code which is PO443 and the old code is still coming up??? Any ideas.

Did you replace the 02 sensor with a factory unit or aftermarket? There is a possibility that the problem is in the wiring to the 02 sensor and not the sensor itself. The P0443 code is your evap purge solenoid. Just clear that one and see if it comes back.
