I'd check the fuel pump, fuel filter, and catalytic converter (02 sensor).

If it were a MAF car, I'd say the MAF is bad. Since it's a 2000, I'm wondering if your MAP sensor is bad- same symptoms, running too rich without throwing a code. Your O2 sensor is probably a better place to start though- when they go bad, the car will run richer instead of leaner, for obvious safety reasons.

Check all your fuel connections VERY carefully. Every single one. If you have a fuel leak under the hood, it will eventually catch fire, and there won't be anything you can do about it.

I'd also check where the soft fuel lines meet the hard lines.
I think there is a problem similar to this with WRXs.

my fuel is cool. But every once in a while, after shifting, I'll hear a nice pop.... could it be Fuel Filter getting old? How often are you suppose to change that ish.. My car didn't come with it's manual. bummer.
