How do I fix Sorento poor fuel economy

Hey scotty I have a 2012 kia sorento sx v6 awd with 42k miles.  I recently changed the engine filter.  While I was doing so I removed the map sensor to give me more room.  I used a oem filter.  When I drove the car I was getting only about 10 mpg from a usual 18 mpg.  The filter was properly installed and isn't clogged.   I decided to try and unplug the map sensor and I started getting 30 mpg! But shifting was off.  I plug it back in and mpg goes way down.  Is it possible that I damaged the map? Is this a common symptom of a bad map?  Thanks in advance.

Replace the map sensor with OEM sensor
