I seem to recall you had the car that ran badly and when you replaced a connection (or a wire I am not sure) to the ignition coil it ran much better. I am guessing you still have some wiring problems that have not been sorted out yet. When you accelerate you are putting the ignition system under a heavier load than idling so whatever is happening is happening under the increasd load. Check out the entire wiring system for the primary ignition system. This includes the wiring harness, the white ballast resistors, the bypass relay, and all of the plugs and connections. You are correct, the timing light should not go out. This indicates you are not getting secondary voltage to the spark plugs. Try putting the timming light on the wire from the ignition coil to the distributer. If it stays lit up then you are loosing the power in the distributer. I once had a rotor short out and I couldn't get a spark to come out of the distributer even though I knew I was getting the power going in! Just because you put new parts in doesn't mean you couldn't have a defective one, or maybe it got damaged when you installed it.
