haha my CEL has been on since a week after i got it inspected last may in the XJ. i keep ripping and melting the wires for the downstream O2 sensor. what's kinda odd though is that somwhere in the shitshow of a run that wrecked my tranny.... the CEL turned off. maybe i shorted the O2 wires enough to make it think there is a sensor there!
sucks you can't just pull the bulb hoping they won't plug it in to check if its not showing any problems with the light, since they plug it in now every year to check emissions
