Help 2G Stalling Problems

[psihigh]

My 2G is sputtering at idle and throwing a little black smoke from time to time. Also, when I drive down the street and I step on the gas, it acts like it wants to cut out and I see black smoke come out the tailpipe. No cel light on. I've put new plugs in, I've checked for boost leaks, none found. Any ideas? Thanks in advance.

Is the BOV recirculated.

black smoke means its running rich ie fuel . when u changed the plugs were they consistent ? also check the maf . make sure its clean , no big leaks between the maf and the turbo . look over the entire fuel side of the system as well

Yes it is

Do you think my oxygen sensor could be bad?

Profile correct with no fuel mods? Running stock boost? Positive you do not have any leaks at all and how long does it take for the air pressure to drop?

It is very well possible that the front o2 sensor is bad. Does your CEL come on for a few seconds when you start the car?

As asked above, were all of the spark plugs fouled the same or were they different?

Yes no fuel mods, running stock boost, and yes all plugs were fouled the same. No cel light at this time. It has come on in the past, but not recently. The car at the moment is just idleing. It throws black smoke and appears to be sputtering from time to time. Thanks for the reply.
