Message Code of P0101 (Map Sensor Performance). Where is the sensor located and is it fairly easy to replace. Engine surges at 65/70 MPH and seems to want to shift. Thanks in advance for any info. Is it likely I can buy at most auto parts stores??

The MAP sensor is on top of the TB. You don't even have to remove the beauty cover to see it.
