DS4 THP 200 Misfire under big load

[BigGingerBob]

HI,

I have a DS4 THP too. Nice, comfy and quick but it has a misfire for about 2 seconds under high load.... sometimes.

It usually happens at about 75-76 mph indicated (3k ish rpm), accelerating for an overtake but this morning, similar rpm in 2nd gear happened again when overtaking a cyclist.

Quite disconcerting really and difficult to predict. Any ideas anyone? No fault codes or warnings showing.
