First thing. Wrong section. Try is the right generation.

As for white smoke. That is coolant generally. May need to look at your head gasket. Do a compression check or check the coolant for carbon dioxide with a tester.

Unusual white smoke at idle is from coolant building up and burning in the cylinders. The misfire can also be caused from the coolant.
