ihave a 1998 nissan terrano ii 2.7 tdi since i filled tank with fuel this weekend has started to miss sometimes and throws out blue or white smoke but not all the time
dont quote me on this one as its just from what i have heard but white smoke can be when the exhaust has water in it maybe if it hasnt been used for a long time and should usually clear but ive also heard blue smoke is that your engine is burning oil, i suggest you get it in a garage as soon as possible and just get it checked over because you may be doing damage to your engine
