Re: atomic 4 igniition points
It's been a very long time since I had an A4.
Have you tried putting on a new coil wire, with the new points? I also seem to remember once getting a distributer cap right out of the box, that had a small hairline crack in it. The Rotors can also get cracked.
How's the timing...? any chance you have the distributer wires out of firing order?
When it's running during that 2 month period how does it run?
