infamous P0400 code

For roughly two years, I have had this pesky code on my car. I tried
cleaning this and that, changed plugs and wires to no avail. this
weekend, on my way to Syracuse, the car suddenly dies on me near
Watertown, NY. I could actually drive it as the engine started again
but kept dying on me due to lack of power. Long story short, I had
the CEL checked out and it turns out 2 new codes were added to the
normal P0400. P0100 and P0101. They indicated the mass air flow
sensor problem. Replaced it and now the engine runs better than it
has in the last 2 years and the CEL hasn't come back on yet. So, if
you have this problem, it could be the MAF. Outback 1996, 2.5 liter
engine.
