Okay, Check engine light is on, but car is running well. Slight rumble and hesitation for the first five seconds, but after that, everything is fine.
Just traveled 600 miles, 200 of those with the check engine light in order to get home from VA to WV.
Slot A2 on the OBD is throwing a 231 code.
Here's a picture of my Cylinder #1 spark plug:

Would this be classified as "lean"?
I've read around a few threads suggesting it may something near the intake manifold, or maybe the o2 sensor.
Any suggestions?
