I did not do a CASE relearn. I happened to have a 2008 Corvette pull up next to me and I could tell his idle quality was much better than mine. I ran an spark tester and found 6 cylinders are firing around 18K volts at idle, one is firing at 6K and one at 27K. My rough idle is probably caused by the 18k and 6k cylinders.
It's too hot during the day and we have had rain almost every night, so not much is going on with troubleshooting the problem.
If any one wants to follow the restoration of my girl friends 280zx, the restoration thread can be found here.
