Well on the way to work this morning i got the check engine light. I took it to autozone and the guy told me its code p0153. I used the search button and understand what it is. My question is i have cat deletes on my car with a tune. Could it be my tune or is a better possibility that my o2 sensor is bad. Thanks in advance

Go to Advance Auto Parts, their code reader will tell you what the code is.

 

Thanks very much!!
