Unburnt fuel, yes,

Typical, no. It means that your running extremly rich.

but he said it's a 'puff' and about 99% of stock dohc vtec's I've seen always have a slight puff, especially on downshift.. :unsure:

are you having black specs all over you back bumper?
my d16z did this and i was wondering what it was

i got a d16y8, and it only appears when im driving hard meaning all the way up to redline. Yeah, it sounds like im running rich but im using a p08 ecu ( 1.5 ecu) on a 1.6 block, so i dont really understand why i run rich. and sorry dude my cars black its hard to see black specs on a black car. the smoke can be one of 3 colors, white= coolant, blue= oil, and i guess black= rich.
