Weird acceleration
Today I started my car up and had the weirdest thing happen. The car struggled to get to 10mph. It literally took about 5 seconds to get to 10mph. This happend 5 times from a dead stop. I almost got hit pulling out on someone and could not get going much past 35 mph.
I had to turn the car off and then back on for it to accelerate normally. Has this ever happened to anyone? It was not a figment of my imagination as I had the pedal floored. It was dangerous.
What could it be?

Accellerator pedal position sensor sounds like its going bad. But if you have Sprint booster installed that could be affecting it.
I have had 2 APP sensors go bad on me on different cars and that is exactly what happens. It will get worse within a week if it is the sensor and the restarting of the car will stop resetting it after that.
The app sensor for standard cars(s500) is only100 bucks or so. I'm not sure how much for AMG cars..?

thank you for the diagonsis. I do have the sprint booster installed but did that about 9 months ago. I will have the car looked at. It felt like the car was in slow motion.
