Ok, I had high NO on my ca smog. I now have check engine light on with the following error codes in this order.

2-3-2: Fuel system compensating for rich or lean mixture at idle
2-3-1: Fuel system compensating for rich or lean mixture a cruise
2-2-1: Fuel system compensating for extremely rich or extremely lean running condition at cruise.

Any ideas where to start?
