Car running again

A couple of weeks ago, after pushing the Plus 2 home, I decided to take a break from the car. This afternoon, I started poking around with a flashlight and found that the plug wire for cylinder 3 had come off! Once I reattached it, the car started right up.

Back to the hesitation & bucking problems. When I was driving the car, after using the brakes, the engine would run rough. So the cause was likely a vacuum leak. To diagnose the problem, I blocked off the headlight and brake servos and found the engine ran much smoother.

I'll do another test drive in the next few days...
