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?

All of my cars have the cel light on. When it is time for inspection I get around to fixing them. Generally if a car has a tendancy for a problem the information and solution is readily available using a search engine.

In your case the manufacturer is on the hook both because of the warranty and because they are required to fix any emmission issues up to a certain number of years and miles. (6 years 80K perhaps not sure since my cars are too old or too many miles).

I'd guess a bad o2 sensor, vacum leak, or bad air temp sensor, but you never know. If you can lose the use of the car then take it in. If not use your best judgement and/or wait until you can. If you start throwing other codes, like misfires, etc. on top of this I'd stop using it as an actual overlean condition can be a fairly serious issue.
