Question about 2001 Kia Sephia
I was driving down the road and all of a sudden it started smoking bad and lost all power to drive but it idled somewhat. I cranked it back up and drove it for a while then it started back running fine. changed the spark plus, engine coil and wires, fuel filter also. It is still miss fireing on plugs 1 and 3. my muffler seem to be down a bit also now blowing out white foggy smoke.it dont runn hot and the oil is not milky. water is still ok green.
Sounds like a bad coil pack 1 and 3,if you change it and it's no help,see if you can find the vacuum hose that goes to the fuel pressure regulator, ,if there if fuel in the hose ,it's bad

Black smoke is fuel.
Blue is oil.
White is coolant / water.
Fuel is caused by timing and cold start system and requires some discussion to clarify.
Oil burning only on start is caused by failing rings on your cylinders. Oil then enters the combustion chambers and burns when you start the engine. If it continues to burn when running in particular when you accelerate it will also indicate ring/cylinder failure. It can also be from a failing head gasket where oil travels from the lubrication system into the combustion chamber. Some of the anti smoke additives available at the auto supply store do help.
I doubt you are seeing white as you say is smells like exhaust. White is coolant in the combustion chamber or exhaust system.
Hope this helps you.
