I had similar problem with my 04 rio base 4cyl. Does it run sluggish at times also? Is the smoke immediate, thick constant or have a odor? It could possibly be a clogged catalytic converter like my situation. I would have the exaust checked, try cleaning the mass air flow sensor& plug, pull spark plugs and check the gaps with a gap tool see if the gaps are ALL correct to ur cars requirements(pre gaped plugs are sometimes incorrect) bc if ur not gettin equal and proper fire to all cylinders it could cause it to tun lean or rich & create heavy emissions/smoke. Also check for any sign of moisture, oil, or burnt/fouled if really chared to whitish brown color which ones are better or worse. Etc I hope you have found or find and get it fixed. I wish knew more to help. Good luck.
