Q: Why will the car not accelerate. on 1999 Mercedes-Benz E430

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
E430 will only accelerate to 1000 and 1500 RPMs. On start it revs to 2500 and back to idle. Changed the accelerator pedal sensor. There are no codes stored. The BAS and ESP lights are on. Brake lights work. And it runs smooth not rough.
