BAD front 02 Sensor Gas mileage.
The results are in 14 mpg!!! Just put the new one in last night hopefully no more PO155 and P1xxx! That SES light is such a little *****! Bosch o2 sensor went bad after only 3 months! I can not state how helpfull the search function is on this site! Hopefully she will be back up to 21mpg now. Just ran some injector cleaner through it today.
