Question: Is It Possible For Catalytic Converter To Go Out,
I have had the catalytic converter change out twice within 10 month period. The check engine light come on again about two weeks ago. I took it to the mechanic and he mentioned that it was catalytic converter. Is it possible for them to go out that quick. Can somebody help?
Best answer for Is It Possible For Catalytic Converter To Go Out
if you are not using factory catalysts , then they will prematurly wear out , but a major factor in taking out the catalyst prematurly is a rich running condition , and misfires , if a car is misfiring it allows raw fuel to go directly into the hot catalyst and melts the reducing beds inside the catalyst , also if this is a 96 or newer car , then have a technician do a duel scope on the upstream and downstream o2’s , a lazy upstream o2 will trigger a false catalyst code , but this is not commen . also if you have any exhaust leaks before the catalytic converter , make sure these are taken care of , unmetered air entering the exhaust system will create lean condition in the catalyst thus raising the internal tempetures and melting the catalyst internally ,
