Oh, I know exactly what's wrong with it, I just resent having to spend more money on it.

The O2 sensor is 20 years old, the catalyst isn't properly working, I have an exhaust leak I'm still putting off fixing and it was probably overheating a little on the dyno.

I'll test the O2 sensor tomorrow, but I already know it's lazy.

They changed the laws regarding catalytic converters last year. I just found out today. Now, it's illegal for shops to sell generic (cheap) converters like the one I put on to pass 4 years ago. They are all vehicle specific and must have valid EO numbers. That doubled and tripled the prices overnight.

So, it'll be $200 for a cat, $100 for an O2 sensor, I have to drill out the broken bolts for the exhaust manifold and replace them, probably should replace my still leaking heater hoses and flush the cooling system.

Or, maybe I should find a job first. I'm not particularly happy about having to spend this kind of cash when I'm not even working.

To top it all off, we went to the tire shop for a flat repair on my wife's van and drove away $95 poorer when they found the leak was in the sidewall. Tires are stupid expensive now.
