I just picked up a 2001 caravan 3.8. 194000 miles.

It smokes white smoke quite bad.(does not have a bluish tint either)

oil is clean.

doesnt smell like coolant. Smells a bit like gas. in park idling smokes a bit, when you give it gas I get alot of smoke. drive down the road smokes, but not as much as sitting still.

No check engine light.

code I do get is P0205 (#5 Injector control circut)

I can slightly smell fuel from under the hood

Has a small miss while driving.

Any ideas about the white smoke??

 

Fix whatever is causing the injector code?
Check the color of the plugs to see if the plug for cylinder 5 shows an overly rich condition?

 

That code would defiantly be something to get looked at by a mechanic. Sounds like a running "lean" situation, or even a dead injector. I would also get the plugs and wires looked at and replaced if any appear to be fouled or damaged. . Keep an eye on your coolant level in the radiator, not the overflow. If it is dropping, I would have it pressure tested for leaks in the headgaskets or intake gaskets. Good luck!
