My car 95 TSi AWD has developed a slight miss at idle , the Vac is perfect , plugs, and wires are good It idles perfect rock steady, and has no miss driving or under boost , it seems to do it more in the heat, when its cool outside it disappears , it almost sounds like it has cams but doesn't lol , any ideas ?

Any fuel pressure regulator? Could be overrunning the stock system at idle?

How many miles on 2G and how is wiring looking under the hood?

Well that crosses my hunch off the list.

Does the regulator hold pressure when the car is off? Has you confirmed it's set to the correct pressure?

Any exhaust leaks? Any DTCs (CEL)? Definitely a good idea to check the fuel pressure as Bryan suggested. Maybe a long shot but, have you ever looked at the injectors or cleaned them?
