Should I have warnings before catalytic converter failure?
I have been told by Ford dealer that my catalytic converters have failed. Should I have had an indication or warning before they completely go out?
There are warnings other than a check engine light, such as a rattling under the vehicle. If the ceramic in the converter totally breaks loose and turns, it can cause the O2 sensors to trip, and a very rough idle. I have seen converters get red hot and in one case catch the carpet in a ford LTD on fire
DOES THE CATALYTIC CONVERTER FAILING, CAUSE THE IDEL TO RUN WRONG OR WANT TO STOP RUNNING , THEN SPEED UP AGAIN ????
