Can anyone tell me why when I start the truck up after its been sitting for 10 hours or overnight, I get a puff of gray smoke then about 5 more seconds of it. It isnt really heavy but I'm wondering why a truck with 3000 miles on it does this. I dont seem to remember my 96 doing it.

Just wondering if this is normal.

Mine does it to. I suspect its normal.

Good. I wasnt sure if maybe I had an injector leaking fuel into the combustion chamber while the truck was sitting and the smoke is just that fuel being burned off. Glad to hear others are experiencing it also.
Thanks.
