Car wont go over 3,000rpms

[SpoolN]

I have a 95 gsx automatic and when driving the car will shift through all gears but in any gear the car will not go over 3,000 rpms the car starts to studder and black smoke shoots out of my exhuast. What could this be any help would be nice

my guess.. boost/intake leak.
Black smoke = rich = more air is being metered by the MAS than makes it into the cyls.

..or fuel cut.

Fuel cut at 3000 rpms at 11 pounds. i would hope not.

I am having the exact same problem in my auto 98 gs-t. There's also a loud woosh of air that that comes on when in boost around 10lbs. I am able to get the car over 3000rpms but only on the highway as long as the car is kept out of boost.

most likely a boost leak, check all tubes, and clamps, and even reclamp them if they seem like they are tight, because when i had my boostleak, i had the same exact symptoms and i thought my hoses were tight. I found the loose hose and it looked like it was tight... Problem solved.. hopefully

Im obv. an idiot haha it was just the hose off the compression housing that fell off so it is all set now.
