Have you replaced the MAF sensor yet?

Customer: replied 11 months ago.
Not yet is that a common part that goes out
Expert:  Jerry Newton replied 11 months ago.

Most of the time, P0101 points directly to a faulty MAF, or a leak in the intake piping. If you have no leaks in your connections and can find no other cause, I'd put a MAF sensor in it.
