Same thing but only when I accelerate

Fuel pressure and flow, exhaust system back pressure, engine timing problems, ie electronics, rev limiter activated.

On a twenty-year-old car like that, I suspect that all you need is an extensive tune-up, and that will likely involve replacing several parts, like sensors. After that, it should run like the POS it was designed to be.

There is no fix. The car was doing exactly what it's supposed to do. The top speed is controlled by the computer. It's programmed to reduce engine power so the vehicle will not exceed the maximum programmed speed. Hope that helps! Jim
