2004 MDX. I have engine light code that says catalytic converter efficiency. I thought I ordered moly that you put in tank. But what arrived was something you spray directly into the air intake.
Not sure how complicated that might be. Or if it is ever effective at all. If it rarely works I'm not going to waste my time.
What do you think? Thanks
