You're Welcome! Ohh man i was so tempted to buying a new MAF too. I actually just did this a week ago and noticed that damn arrow pointing towards to the air filter. i was like what the heck is this arrow for!? I did what i told you and after that reset my car (Unplugging the negative connector on the battery since i didn't have a OBDII scanner for about 10 mins) and bang drove the car so far no CEL.
