Ha autozone. That’s like saying we’re YouTube certified techs. Well just so happens, I’m a Honda tech for over 14 years. When I get in tomorrow I’ll log into Honda Interactive network and see what the troubleshooting for those codes are. I believe there is a bulletin about checking the timing to see if the marks are correct. If out of time, the pcm could be adding fuel to try and achieve target AF. But lemme check and I’ll get back to you.

There is a bulletin about checking timing. Possibility timing could be off. If marks are where they need to be
next step is to check fuel pressure. If too high, check pressure regulator and fuel return pipe.
too low check pump, feed pipe, fuel filter and press regulator.
if fuel pressure ok check primary 02 with scan tool. Hold eng rpm at 3k without load until operating temp. Check sensor 1 (primary) output. Does it stay less than. .3v or more than .6v? If so, replace 02
if no apply vaccume to evap canister purge from intake manifold side. Does it hold vaccume?
yes=check valve clearances and adjust, if clearance is ok, replace intectors
no=replace evap canister purge valve
end of dtc troubleshooting for p0171/p0172
in p1457 2 things that are mentioned are the canister purge valve. Id check the connected at the purge valve and also check hoses if cracked or broken. If you have access to a scan tool, you can disconnect the purge valve and put a test light on the connector and activate the purge. It should light up. Also with it plugged in, and commanded on, yiu should be a able to feel it click. No click is a indication the valve is ng or stuck in the position it’s in.

Even if the chain was stretched to a point where the engine would no longer sync, and run (timing tabs on crank and cam so far off, ECU deems piston-to-valve contact) it will not set a rich code in an S2000.
The only way they could be way out is if the motor was recently assembled out of time.
Valve clearance would be my starting point.
