Simple answer: air/fuel mixture is off. Too lean means too little fuel, too rich means too much fuel. Can be adjusted via air/fuel screw on a carb or via a remap on EFI. If you make changes to the air flow, you need to adjust the fuel as well.

What is running lean and running rich?

"Rich" and "lean" refer to the air/fuel mixture. Rich means a higher proportion of fuel than is needed and lean means less. An overly rich mixture can foul plugs, cause sluggish performance and promote carbon buildup in the combustion chambers, as well as decrease fuel economy. An overly lean mixture can cause jerky, hesitant performance, overheating and in extreme cases even melt a piston crown.
