hey, i have been noticing that when i get on boost the car will continuously smoke untill i let off the throttle when it is cold out ( but not too cold because i am in south florida) or at night. the other day i had my friend drive the FD during the day (warm out) and when he gets on boost black smoke will come out but not as much as when it is cold.
The smoke is definatly black or dark grey not white or blue.
what could be going on?

 

eh check the oil drain pipe for the turbo, that could do it,

 

er- becareful what you inhale while speeding. Drugs & Driving don't mix.

 

I know this sounds like a kill or something, but it's true, and pertains to the topic, I was on an on-ramp in L.A. and had to wait for those pesky onramp lights, when I started seeing a porsche trying to blow past me once the light turns, (He was moving I was standing) well needless to say I gun it and check the rear, the whole time, and I see black / grey puffs of smoke in the rearview. Yet my car doesn't burn much oil nor does it smoke during heavy acceleration once it's been warm for a while...

So this occured somehwere between warmup and full warm temp. And seems to be related to a poorly warmed up engine...

It sounds like you guys have too much fuel coming in to the combustion chamber. It is probably one of your sensors. I am not an expert on these things, so I won't pretend to be. Do a search on the subject.
