Hello fellow Mercedes enthusiast i purchased a 2003 c32 AMG the other day with zero issues but while driving home when i pressed 100% of the gas the car lost acceleration, jerked, then went into limp mode and threw a misfire code for cylinders 4, 5, and 6 and a small evap code P0446. if i restart the car it drives fine only if i punch it. the fuel pump, and spark plugs were replaced but no change. a compression test was also done and everything seemed fine. if i clear the misfire codes the car runs fine with no check engine light. any suggestions on what to try. thanks!

Possibly the throttle pedal is overextending if it only happens under full throttle. It’s an issue with these pedals.

Would you know a way to diagnose this issue or if i could use any w203 pedal thanks!

Does the car only go into limp mode under 100% throttle ( push it all the way to the floor?)
