1999 Subaru Legacy engine hesitates intermitantly upon exce

The engine is the 2.2L single overhead cam model.
Like I said, knowing of the problems with MAF's in 1999 I'd be reluctant to buy a used part.
Before I cough up $245+installation for a new one I'd like to be sure it is what I need to cure my emission problems (idling).

Just thought you'd like to know that after further research (www. Repairpal. Com) I discovered the recall in 2002 for MAF sensor on my vehicle. I double checked on www. Epa. Gov/ltaq/recall. Htm and it was confirmed. I called a local dealer and he punched in my vin# and said that it did not show any active/or closed campaigns on my vehicle. The reason that it did not come up I suspect is that my vehicle was originally meant for the Canadian market. I had a lot of problems getting an emission label (needed for smog to be performed). I had to write to the mfg for a letter of compliance and go to a smog referee to have it applied inside my door jam. I am the second owner and would not have gotten notification of this recall. I hope that I am able to have it fixed under this recall, but I have to hear from Subaru/Canada. Thought you might like this info to pass onto others having the same problem. I cannot believe all the problems I have encountered in trying to correct an emission problem and not lose all the money I have tied up in this car ($4800) by being labeled as a gross polluter and having to retire it to the junk pile and the state being so kind as to give me $1000 (how generous of them).
