this car uses electronic throttle controls, when a fault occurs in the electronics the computer (ECM) limits the amount of travel the throttle can open to limit the load on the engine to prevent any further damage, when the fault clears itself as they often do the throttles are returned to normal operation, the limited throttle is called "Limp mode", what u need to do now is have the dealer test the computer (ECM) for fault codes that may be stored to explain why the system was put in "Limp mode" with the resulting loose of throttle control..
I had a similar problem with my 1994 S420.
Before taking it to the shop check the following:
Distributor covers, Rotors and Spark Plugs. That's what my car needed. Before I did it two "specialized" MB mechanics wanted to replace the engine wiring harness ($1,000.00) and the other wanted to replace Air mass sensor, throttle valve actuator ($2,000.00) I hope that's all you need.
