Have a service engine soon light that has been constantly on for a while now.
Was read via scanner by one mechanic who said it's the catalytic converter and needs to be replaced, or the car won't pass emissions inspection.
The car's performance has been fine, however when I previously brought it to the same mechanic a month ago regarding the check engine light, he said it was the O2 sensors and ended up replacing all 3 of them for about $600.
Does this seem right? Did the sensors really need to be replaced the first time, if the scanner was also reading "catalytic" problem back then?
would an aftermarket catalytic converter be a good idea for this vehicle, with the year and mileage on it?
