Accelerater problem 1997 Mecedes C 200 Elegance

run fault codes and check for accelerator position sensor problem Check for MAP/MAF sensor faults.

if you can find away to read the codes you will probably find that it has a bad throttle position sensor

Is your check engine light on while your driving? If it is get a hold of a scran tool to find out what codes are showing.Or most auto parts supply stores have one end will check it for codes, Most of them don,t charge to check it out for you.

sounds as if the accelerater cable broke, when you were able to throttle under the hood did you happen to notice if the accelerater cable was moving freely.

Check your universal joints in the drive shaft. When you remove your foot fromt the accelerator you are no longer applying power to the rear wheels and in turn there is no load on the drive shaft. When you accelerate below 40mph, there isn't enough centrifugal force to cause the driveshaft to wobble, but once you go above 40mph, it begins to show slop.

Another thing to check is your wheel bearings.
