2 years ago I brought a new catalytic converter for my car from DE dealership. That cost me 496. 76$ few months ago the check engine turn in and when I check I have the code p0421. That is the code for the catalytic converter again. I couldn't believe it. I when to Mitsubishi 2 days ago and they told me that they couldn't believe it because I'm the first client that comes back for the same part. One of the employees check my car and he said that my car is burning oil. He told me that I have to change the valve lifter. Do I really need to do that then buy a new catalytic converter?.
