What are the symptoms of a bad catalytic converter?
The CEL keeps coming on but the error code is "vague" and sounds to me like it could be the catcon or even O2 sensors!
Money is tight for me and I can't replace BOTH the O2 sensors and catcon at this time and want to replace only what is bad.
There are two O2 sensors total cost abt $200...and of course the catcon is abt $225.... not including labor for all this.
My CEL keeps coming on and my gas mileage is poor.
I always thought a catcon was good for life of the car. Is 151k too soon for catcon to be bad?
If you were gonna choose between the catcon or the two O2 sensors.... which one would you have replaced given my symptoms above?
