Just a few hours ago,my 2006 honda accord 4 cyl. Starting letting out a lot of white smoke with an funny odor.It also hesitates when I try to pull off.I stop the car and restarted it and white smoke began coming out the exhuast then fade away.I go to drive and the same thing happen again at a stop sign.What could it be causing this and how can it be fixed?

Sounds like it's a bad head gasket.

AMEN

Blown head gasket, likely due to overheating, is allowing coolant to be burned. Check for warped aluminum head and damaged valves.
