no the cat is still there. i just had to replace the o2 on them. now i'm trying to install an air fuel gauge and afc on my car because i think im running too rich. any ideas?
i installed headers and an exhuast and 2 weeks later the check engine light came on. it's 2001 and it has about 85k miles on it. how much would an cat cost me?
Hi, I'm have a problem with my IS 300, I took it to Advance Auto Parts and did a DIAG. test and it gave me a reading.
