Being a novice at this I post my question as such. I have three opinions as to why my check engine light came on and all say code po430, oxygen sensor, bank 2, front, meaning I have 40% obstruction in catalytic converter. If I keep the truck as I expect to, I should enventually replace the converter. Question is, is this the solution and what is the most economical way to do it? Thanks...
