I just changed the individual coils and spark plugs on my son's Navigator because it seemed to be running rough. Though the vehicle is running fine, I'm getting a P0430 - Catalytic Efficiency is running below threshhold Bank 2. I smell the faint odor of gas. I'm not getting any misfire codes, just the P0430.
Exhaust system doesn't seem to have any leaks. Do I have a misfire condition or should I be checking something else. Any help would be appreciated.
BTW - I've used this forum for some years now. You've all been great.
