E66 - Cruise - Engine RPM Too High

I noticed while using cruise control, a minor bump or switching lanes and hitting the little things in between lanes can sometimes cause my cruise control to stop and I'll have to gas again... and when I check the codes later on I always get:

E66 - Cruise- Engine RPM Too High

after the occurrence. How do I tell it to not keep the RPM so high or fix it? What's really happening? Thanks for the knowledge! :hmm:
