does yours happen under heavy acceleration at about 5-6000rpm on full boost??

That points towards the coilpacks if its happening above 5000rpms, but yeah, regapping your plugs and giving the afm a clean wont hurt

after you done/tryed all thats mentioned by other peeps go buy some AFM cleaner and clean up your AFM, it all helps

+1 i bought some contact cleaner for afm from autobarn @ 20bux and game my afms a clean and the car seems to idle better and feel smoother in the rev range; although it probably aint the problem, i now think its a must as afms seem to get dirty quite quickly.

i seem to be geting this problem aswell, although my s1 r33 seems to spitt out white moke after backing off aswell. havent changed anything yet, coils,plugs probly, could a buggerd turbo be causing all the white smoke??

white smoke = oil

black smoke = fuel

white smoke probably means you've got a dodgy oil seal somewhere in the engine, either piston rings, or turbo.
