It started with the check engine light, so I have the codes checked. The first code was PO431 and secondary was PO455; So, I had all three cats replaced and all 4 O2 sensors. Now I got code PO466, so I had the purge valve and the vent valve replaced. Checked all the hoses, the gas cap and the check engine light goes out for a little while and pops back on. The vehicle has been rejected at the DMV twice.
Can you please, please help?
have the same problem?
