Sometimes (I guess two or three times a week) the engine hiccups, only when accelerating (not necessarily madly), and doesn't seem to matter if cold or warm. Usually just a single hiccup, occasionally 2 or 3, before continuing as normal. Regularly serviced - 75K service a couple of months ago didn't fix it.

Any ideas where to begin looking?

Thanks,
