Too much fuel getting to catalytic converter. You are going to ruin your converter when light blinks. Unburned fuel). Do you have a large vacuum leak code? Leaking fuel injectors? Sounds like engine getting too much fuel based on air intake that it cannot combust all the fuel.

I am asking about vacuum leak. Do you have a code for it? This is a sign for computer overcompensating and giving too much fuel.

How can I find the vacuum leak? An there a Hissing sound coming from the motor
