Look at thr rear of the engine, just to the right of the distributor and you'll see the vacuum solinoid with a vacuum line going to the distributor and another going under the intake manifold. There is an electrical connection that should be plugged into the solinoid and it's very easy to bump it loose when you're messing with things in that part of the engine compartment. If it's unplugged the engine would act just as you've discribed. Bruce Benson
