Landcruiser 80 help

[a80crewza]

When I start my 80 up in the morning or after work it puffs grey smoke for a bit. Also puffs grey smoke when i put my foot down when accelerating. Idle also seems low and quite rough when starting in the morning. After its got warm it runs like a dream. Is it just over-fueling? Just wondering if I should be concerned? Thanks.

mine does the same mate even when warm idling it pufss a greyish blue haze. it appears a common thing on the 80 series. my acds system has been removed which makes it a bit lumpy on start up on a cold day. has ya injector pump been checked or ur injectors, this seems to be the common cause. mine is have ip pump timing checked nxt week then injectors will be done. u can spend a lot of money chasing the smoke.
