I have searched and searched and no answers on how to fix this.First check engine light was a code 1 for primary O2 sensor so I replaced it and the code stayed off for about 30-40 miles then the check engine light came back on but this time its a code 61 which is O2 sensor again I have checked the connectors,wires,and everything.And cant figure out why one code then another.

 

Surely someone has had this problem and fixed it

 

Its highly likely its not the o2 sensor being bad, might be that it is getting a high/low reading or slow response.

I would need more than 61. try to scan the OBD2 port with a scantool/codereader to get the PXXXX code.

 

Check for an exhaust leak.
