It's running rich probably......fuel pressure regulator or fuel pump or bad signals from an 02 sensor or something. could be many things but it sounds like that could be one of em..
good luck

You don't have a carb. Carbs haven't been used in cars for a long time. The car runs rich you need to retune the fuel map as it is electronically fuel injected.

How much black smoke?

I mean, I know the MSP runs rich stock .. but I still have the stock EMS, and I've never had black smoke pouring out of my muffler at idle. Ever.

However, it does sound like a tuning issue. The bogging down. Does the car have any engine modifications that you know of? What did you clean out, since we know it's not actually the carburetor? Did you try smelling the exhaust fumes?

Your intercooler pipes attached?

Your intercooler pipes attached?

Exactly what I was thinking.. BOOST LEAK!

Although, if your car has a carb.. I think you got jipped on the MSP..

Carb huh? Maybe he has a NASCAR msp. shweeeeet.

Im thinking it wouldn't be an IC pipe because then the car would die out at idle or at least rev real bad. could be tuning... wierd problem, subbing for progress.

They could be attached but loose in a pressured spot.. As he's not getting enough required air to the motor so the ecu throws fuel which in turn puts out black smoke from being REALLY rich..

Check the gap on your plugs.. Also check to see what kind they are as well... If they arent NGK's get some..
