2.4 jtd intermittent lumpy start up/idle

[RedemP]

hi all,

first post.

im almost 3 months in now with the 159 ti 2.4 jtd, and nothing major apart from a few niggles.

but i have begun to notice a bit of a lumpy idle immediately after start up. you can hear and feel the engine revs rise and drop ever so slightly a few times before settling. happens from cold and when warm, but seems ok when idling stopped at lights.

has anyone come across something similar?

thx.
