Clean the MAF. While you are out getting the safety torx bits, get a can of CRC MAF Cleaner. Do NOT use anything but this or electronics cleaner on the MAF, and I don't recommend you using a Q-Tip on the MAF. Those wires are quite thin and if you break on, well you just bought a new MAF. Just spray the crap out of it until both wires are clean and let it air dry before reinstalling it.
