i really need some help here, my car has two codes that i pulled out of my car. code p0170 and p0172. i need to know how to fix it. i know what the code reads, because i have an obd2 scanner. what i need to know is how and where to fix. if anyone ever got these codes and fixed it, your help would be nice. oh my car is a civic si 2000.

A stock '00 Si? How many miles? Did you just recently get these codes after adding something/doing some maintenance? Have you reset the ECU to see if they come back? What does the maintenance history look like: cap, rotor, plugs, wires, fuel filter, valve lash, O2 sensor, setting the timing - those sorts of things?

P0170 Generic Fuel Trim (Bank 1)
P0172 Generic System Too Rich (Bank 1)

a tune up would fix this as EEchris has pointed out , I would like to add you should also try some fuel injector cleaner

i've bought spark plugs, caps, and rotors. i've checked my timing, and everything seems fine. only thing left is probably changed my fuel filter...
