Check to make sure the catalytic converter isn't plugged. Also, if the check engine light is on, have the computer scanned. Make sure there is proper air flow through the air intake system.
There are a few things that can cause this. You listed a couple. The MAF, TPS, vacuum leak. The check engine light is your greatest helper if it is on. Otherwise, it becomes a guessing game.
