113: fault in fuel injectors
212: oxygen sensor signal absent or faulty
232: fuel system compensating for rich or lean mixture at idle

How is the car running? Is the idle really rough? If you unplug one fuel injector at a time while it is running, does the idle get a lot rougher?

Make sure the oxygen sensor connector has clean and tight connections. The 02 signal is carried by the single wire (green, I think) thru the spade connector cocooned in a rubber cover on the passenger side back near the firewall. The other o2 wires are for the sensor heater circuit, don't worry about those (as long as they're plugged in).
