If the vacuum advance does anything at idle, or under any 
conditions that you can emulate standing still in the driveway, then 
it is not working properly. I don't know how this could happen on 
the FI engine, as there is only on place to hook it up, and that will 
have no vacuum on it under those conditions.

So I'm a bit confused....

If this is just one cylinder not firing right away after a cold start, 
then it may really not amount to much of anything. I've had 
problems like that that I THINK were related to too rich a starting 
mixture which often left one cylinder flooded. In my case, if I would 
go ahead and pull out of the drive way, pick up speed and then 
take my foot off the gas and let the engine brake me down to the 
stop sign 3 blocks away, this would clear out the engine and 
everything would be fine when I pulled away from the stop.

Is this what you have?
