My name is ***** ***** I am a professional here at Just Answer. I noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
Inspect the wiring leading to the oxygen sensors on the exhaust system and see if any wiring or connection issues are found.If an issue is found with the wiring it will need to be repaired to correct this fault here.If this is or was checked and found o.k. let me know.
Thanks Pete
