Posting the trouble code will get you the most accurate help.

anyone know what that code might be??

I know, I know :D
"O2 sensor signal stuck lean" generic code

The computer expects to see the voltage swing on the primary sensor, and when it doesn't everswing above .5 volts the ECU has a hissy fit and throws a code.
I would first check the connections to the sensor. Next is to watch the voltagereading with a scan tool or meter.

Someone else had that same problem and it turned out to be some oil in the connection.... so like Hondadude said make sure that your connections are tight and clean on your O2 sensor (located on your exhaust manifold)

There's a service bulletin on that. The ecu needs a software update.
