Car stalls when placed in drive or reverse. Will stay on in neutral or park

My 2004 Mercedes clk 320 starts up fine and will remain on when I'm in park or in neutral. When I place the vehicle in either drive or reverse the vehicle either lunges forward or backwards (depending on the gear I'm in) when I have the brake pressed down. The car will eventually stall. I am able to turn on the car and repeat the process. I was able to place the car in drive (quickly) and drive it homebut the minute I press the brake and am about to come to a stop the car stalls. Please help

I Placed the key in the ignition, placed it in the 2nd position before it cranks up. Pressed the throttle for 5 second and the released. Then I left the key in the ignition for 2 minutes and no luck. I read online this is how to reset the adaptive memory.

it is better done with a scan tool. you should let a shop do this for you as they can verify the readings on the sensor.
