So happy no smog check in my county. If you have black smoke out the tail pipe it's not lean its rich. In complete combustion.

Coolant is full. Read a trick somewhere saying to hit the cat with a mallet to get some stuff loose, then go full throttle to clean it out. Don't know if that was serious or a joke, but I'll try anything.
[!!!] Found an exhaust leak. Put a rag in the tailpipe, checked under the car and under the hood, and found an exhaust leak right after the cat where it connects, where the gasket should be. Looks like I'm going to be replacing that gasket. But would that exhaust leak really make a difference, and also it being after the cat? I know nothing about anything.
I read somewhere on the internet (lol) this person replaced their cat and still failed. They found an exhaust leak, changed a $3 gasket, and then passed. Boggles my mind. I don't know if an exhaust leak can cause 3000+ NOx readings, but I know I've got one, and I'll be changing that gasket.
I've got to read up on checking vacuum. I'm planning on doing a compression test and putting the tester where the O2 sensor goes. I have no idea what I'm doing. Yeah!
