The gray smoke has me a little concerned. Did it go away? Has it come back?
Here are my concerns:
1) The gray smoke could simply be the result of a rich fuel mixture. However, a very rich mixture usually produces black smoke.
2) If the car sat for that long, it may have been condensation.
3) Where did you notice the smell coming from, under the hood or from the rear of the vehicle?
4) White smoke on start up usually indicates coolant getting into the combustion chamber and burning with the gas. Have you noticed that the coolant level is low or have you checked the oil to see if there is any creamy substance mixed in that would indicate coolant getting past the head gasket and into the engine?
Let me know.
