My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received 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.

The first thing that needs done here is to have the fault codes checked/read out to see what codes are set.Once this is done any codes set need diagnosed to help locate and repair this issue here.This needs done with a fully compatible scan tool that can plug in and read all computers in your model.If you can get these codes and post them here this will help us continue here.If not let me know.

Thanks Pete

First, the codes indicated that an O2 sensor is bad. Did not identify which one.

I apologize for the delay as an emergency had come up.

Can you post the code number(s) that set?

Let me know,thanks Pete
