same problem

hey guys i need alittle help i posted about a problem i was having a week or so ago then the problem seemed to go away. the problem has now returned. i have a 91 automatic and when i go out to drive it i start the car and drive it runs fine boosts up good runs all the way to redline under hard acceleration. drive the car for like ten minutes and all of a sudden everytime i jump on it the car bucks around doesnt want to rev up and hangs around 4000 rpm. also from someone following me its puffing smoke pretty good when this happens. any ideas?

"Bucking" - "typically" means a Boost Leak - Typically a Clamp has slipped or Failed, or a hose leaking under pressure somewhere between the Turbo & Throttle Body.

thanks man i thought that may be my issue. i looked and all the clamps seem tight but its not for sure just wondering if it is a boost leak though why its not affecting anything before the car warms up.
