OT: Dreaded CEL in my DD, Got the OBDII code Options

[flipb]

My daily driver is a 2007 Kia Rondo, 2.4L 4-cyl. I bought it new and I've put 50K miles on it.

About a week ago, the Check Engine light came on. I decided it was time to own an OBDII code reader, so I went out and bought one at my FLAPS.

I hooked it up and it gave me the code P2187: System too Lean at Idle Bank 1

I presume the "Bank 1" part is the default for an inline engine.

I figured it was an anomaly and cleared the code. Within 2 days, the Check Engine Light was back on, and giving the same code. This time, I didn't clear it (so the light is still on every time I drive... much like every NYC taxi.)

I can discern absolutely no difference in the way the engine's running, sounding, or driving. I suspect the weather may be a factor - both times the light came on, it was a fairly cold morning. I'd be more concerned if the diagnostic code implicated a particular faulty part, such as an O2 sensor.

Should I worry? Should I clear the code? Should I get to a dealership soon, considering there's a 10yr/100Kmi powertrain warranty?

Easy thing to do, call your local dealer and explain the problem and see what they say about emissions coverage for your car. Worst thing to do is start throwing parts at it. Alot of codes can come up that sound very straight forward but have an underlying problem that fools the computer into setting a code for what it thinks is the problem area. If your not covered under warranty, make friends with one of the dealer smog/drivability techs and supply enough beer to get it fixed.
