it's incomplete combustion one way or another... either rich, or incomplete burn.
check heat range of spark plugs, check your timing, check the color of your spark, the condition of your injectors (of clogged, they may be spraying a ghay pattern instead of properly atomizing), check your O2 sensor volltage... and then get back to us. cuz there still could be other things wrong but they are less likely.
