    What the heck is a mass air flow sensor?

    This is the question I was forced to ask myself yesterday afternoon when I was on the phone with my mechanic. You see, I was driving home on the Mass Pike Wednesday night, and as I slowed to yield for traffic, my car suddenly jolted hard and died. Someone somewhere was testing me because I found myself cruising at 40 mph in the middle lane with no gas and only my brake. My wheel froze and it felt like the engine had seized up.

    Fortunately I was able to coast my way into the breakdown lane, and eventually to the Framingham rest area while I waited over an hour for a tow truck to arrive. Inhaling Doritos and a Gatorade was not my idea for a nice dinner after a long day of work, but I had little choice. Actually this week in general has killed me and that's why you haven't heard from me lately.

    So, back to the mass air flow sensor: If you're curious you can get your answer by reading this PDF. I have no interest in learning about the sensor, but I did have to learn it would cost me quite a bit to replace.

    But the story has a happy ending. A new sensor has been installed, and I had no trouble driving to work this morning. It's Friday which is also good news, and I'm looking forward to sleeping away the entire weekend.
