also check all the connections on your iac, tps, maf, map, etc.
I would check this first. I had similar problems when I first got my car and hosing it out with some parts cleaner seemed to work fairly well.
Another thing though, did you reset the computer after replacing the MAF? Disconnect your battery for 5 or 10 minutes, reconnect and then let the car run for a few minutes. Sometimes the computer has to "get used" to new parts and its easier to have a fresh slate than having it reconfigure the tune while it still has old MAF info in it.
