gas petal on 1996 Buick Park Avenue

after accelerating over 50 miles and hour my gas petal wants to stick after I have come to a halt.Also the engine acts as if it wants to quit. I only have 58.000 original miles on the car .Most of my driving is in town and I only drive 2 Miles to work and drive 20-40 Miles an hour

Have a shop check this out, a sticking gas pedal can be dangerous. It may be a dirty throttle body, or something else that is causing the throttle to stick.
