Leaking injector?

[nextse7en]

Hi there folken' this issue started last night (at least I noticed it last night)

When I started it up a white cloud of smoke poofed out of the back (note, last night it was about 55 deg, I'd imagine it was fairly high humidity) the smoke didn't dissipate for quite a while, just hung out there for about 40 seconds. The smoke continued to come out the back the entire night, though not nearly as dense.

This morning, it happened again - though much less severe - and no vapor came out after the engine had warmed up.

Coolent is clear - I flushed and chainged the oil today - honey colored after 3k

No C.E.L. action - But when I filled up today my milage had dropped about 3mpg from last week.

Could I have an sticky leaking injector? The smoke didn't smell like gas - it smelled like typical exaust.


Help on this would be greatly appreciated.

Thanks.
Patrick.
