Have Mercedes Questions? Ask a Mechanic for Answers ASAP
Hi. Generally from the symptoms you describe, the problem sounds like the throttle body. Not the accelerator pedal position sensor. The throttle body is more common to fail and cause surging, and delayed response. I would have your mechanic check into that. Please respond with your comments or further questions. Thanks.

Wow, ok. Someone must have bent the pins over at some point. Glad you are back up and running though. Thank you.
