New O2 Sensors and MPG dropped??
I just changed my front A/F Sensor (Cali Spec) and rear O2 sensor and my MPG dropped about 4mpg...what gives? Any ideas? Used OEM sensors, Tire Pressure is good, weather is getting colder but shouldn't effect MPG that much.
What do you guys think?

Cali Spec has an A/F and O2 back. I had a CEL before thats why I changed the sensors out. I unpulgged the battery to reset the CEL, and been running really smooth ever since...but getting 14.xx MPG.

If you still had the old ones you could try swapping back one at a time and see if it is actually the sensors or just maybe that they switched to winter gas during your swap.
