Ok, so I took it to another mechanic to ask about the MAF and throttle body, and the car actually did the "crazy start" thing in front of him. He said, right out, that it was the fuel pump starting to go bad. He asked me did I feel a hesitation around 40-50mph, and I do. I just attributed it to "random crazy things" this car has always done, so it didn't really send off a red flag to me (I am, by no means, a car expert!). Thoughts???
