Theres a chance that if you've been running rich for too long (either too much fuel or not enough air.. ie boost leak) you've slowly fouled up the o2 sensor today it reached its breaking point... hate to be pessimistic about it but its happened to me

You can also look at / watch the trims on the AP. If the long-term is maxed out at 15, it will throw a cel. If the short-term is oscillating at idle or consistent cruising then it's time for a front o2.
