Distributor rotation for 1987 Audi 4000 CS Quattro

[Huw Powell]

First, I think you should keep list discussions on the list.  Use "reply

Second, why don't you tell us the whole story from the beginning?

You didn't hurt the coil.

But what did you do between it starting to run badly and mixing up the 
ignition wires?
