Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have 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.A bad cat can either slowly restrict or in some cases it can happen all at once, the best way to know is to loosen the exhaust so it has a healthy leak and see if the problem clears. As for the sensor I suspect its a temp sensor but with out seeing it or the ash It is hard to say for sure, can you post a picture of it for me and let me have a look?
