Turns out it was the bulbs. You CAN have the low beams work when the high beams are burned out. I also found out my fuel pump went bad, so there's that too. Symptoms were it had an intermittent bog at or near WOT. It also ran out of gas going uphill when I had a couple gallons still in the tank. It's a tough one to diagnose, due to the intermittent nature of the failure.
