slight stumble at idle

[Roverclaud]

My 04 D2 has a slight stumble at idle. It idles at 750 rpm, over 800 rpm it smooths out. I’ve replaced, plugs, wires and coils. Compression is good, leak down test…ok

Your thoughts
Thanks

No not yet. Haven't spent much time troubleshooting it, maybe this weekend.
