Sounds like the head gasket blew and exhaust is entering the cooling system and exiting threw the heater core. Does the radiator smell the same? If the coolant is low and the smell is in there as well you have lost your head gasket.

White smoke is coming out of my vents

White smoke is usually indicative of a blown head gasket. Usually if you have blue smoke it's oil......If you have white smoke and possibly a "sweet" smell to it, that's normally coolant.
If it's coming out of your vents then I'd say you need new gaskets now. What's happened is the gasket blew out so bad that the smoke made it's way through the vent system, it's also coming from under your hood I bet giving my past experience with this.
Definitely new head gaskets to fix this though.

Why is there white smoke coming out of the air vents in my 1995 grand marquis

It is either steam from the cooling system and will have an odor, or is frost from the a/c system due to a system that is restricted and freezing up. Or you car is on fire. If it smells like smoke, run or you will die from smoke inhalation or burning to death.

Lose of power and low fuel consumption and puffs white smoke when driving dtc showing code p1386

The white smoke is a concern. When there is white smoke present after the engine has reached operating temperature, this can be a sign of antifreeze getting into the combustion system. That can come from a couple of places depending on the vehicle. The most common place is from a leaking head gasket. If this engine has at one time been significantly over heated that is a strong possibility.
The mixing of coolant with the combustion can also cause very poor performance and stalling.

One of the tell tale signs of coolant in the combustion area is a sweet acrid smell from the exhaust, similar to the smell of maple syrup.

If this is the case the only permanent solution is a head gasket replacement and head reconditioning. This is a major expense and undertaking.

Bad smell coming from heater/ smoke coming out vents

I had the same problem in my 98 Dodge Dakota! Replaced the heater core, problem solved. No more funky coolant smell and erie fog coming through my vents. I bought the heater core at online. Have purchased many items now from them. All factory parts so far at half the price of even AutoZone, even with the shipping. Also, you usually have to wait only a couple of days depending on the part and they have EVERYTHING.
