I was driving back home after being on the highway for 6 hrs today, and then my check engine light and my battery light came on. The battery light kept coming on and off, and now, if I go and clear the code in the car, they both shutoff, then light back up (when running), and when its on but the motor isn't turning and I clear it, the OBDII tool reads that their are no errors.

Now my friend (mechanic) said that the blinking battery light could be caused by a bad alternator, and that a working alternator would be providing 14 volts at the battery, however, after measuring, I got 13.2 Volts. I also read online, and its suggested that maybe its the wire leading from the ECU to the MAF. I also cleaned my MAF, and let it dry for several hours prior to reinstalling it, and I still had my problems. Now I should note that I have a AEM cold air intake, and its been running problem free (besides dirtying the MAF once or twice before) for 2.5 yrs.

What should I do to solve my probs?

i had the same problem. i had a aftermarket intake and the bottom motor mount is so weak that the whole engine moves so much that it broke a couple of the wires that go to the maf sensor. the wires are very small gauged wires. i was able to ring out the wires and find the bad spot. it was only about 4 inches from the maf sensor plug. you just need a ohm meter and stab the wires to find the bad spot and solder them back together.
