Coming home from a friends, I noticed my engine light did not go out. I got home and turned off my Jeep. A few minutes late I re-started the Jeep and the light was still on. I turned it off again. About 15 min. later I went and pushed the odometer reset and turned the key to run. The numbers that displayed was "8" then "2.1". All the gauges went through their calibration steps and I turned the key off, re-started my Jeep and the check engine light came on then went off. I've had no problems what-so-ever with the Jeep running correctly...I mean with the idle, transmission, shifting or anything. I have an '02 with a 4.0 w/ auto trans.

Does anyone know what the "8" AND "2.1" represents?
