Just in case anyone is curious, I found the problem. While troubleshooting the MAF power (prior to engine light and codes) I created my own secondary problem; I had blown the 10A fuse (#43) by incorrectly testing the voltage. I'm obviously not a mechanic and made a mistake that added to the Joy of fixing a vehicle. The original lurching and hesitation problem is gone too...gotta love cars that strangely heal themselves!!
