PO420 questions
Hello there,
i have thrown this code twice now. I thought i had rocks rolling around in the wheel because it only happened at low speed, about 10km/h. *removed tire and checked*nothing!*still rock sound* Does this have anything to do with the catalytic converter or O2 sensor? Also if one cat is bad and there are two on the yaris could i cut one out and replace it with pipe? This is the way it is right now. Manifold --- cat--cat--resonator ----muffler i want to do this Manifold---cat---resonator-----muffler Will this configuration damage the motor? Thanks! |

if you have an annual inspection program tampering wiTh emmissions could lead to trouble..
Could be that lower o2 sensor that checks efficiancy. I just changed it and did a writeup with pics.
