With our E320 wagon vs the 300E, the throttle is stiffer and has a much different feel to it.
I went through and lubed all the linkages, pivots etc and it did make a difference. Afterwards, the initial application of the throttle is easier.
I was also told that possibly the throttle cable itself needs to be replaced since it cannot be lubed.
