I will have to replace my catalysts and since I'm in CA, it's expensive. I have 145,000 miles, although they failed probably around 125k. Is this normal? I will have to replace them to pass smog, however, is there something that caused them to fail? Would hate to spend the money only to have them fail again for my next smog in 2 years.
My truck is well-maintained as far as spark plugs, air filter and oil changed regularly. Have read a poorly running motor can ruin a cat.
Thanks!
