Hello,

Any help would be greatly appreciated.  I recently got my oil changed
and asked the dealership to check why the engine light was on.  He
replied that the Mass Air Sensor needed to be replaced.  This, with
labor, would cost $900 so I went online and bought a new one for
$250.  I installed it correctly, but unfortunately the engine light
still remains.

Am I supposed to drive it a few times in order for it to correct
itself?  I should also note that I recently installed a K&N cold air
intake on the car as well.

Any suggestions would be greatly appreciated.

Thank you,

Sean
