I know it's an old thread, but if someone searches for this problem, they might find my experience helpful if nothing else works.

We had a similar issue with stuttering and no power. It got worse over time until it was every time you stepped on the pedal it would not move faster than a crawl. I did all the regular diagnosing and found nothing. Then I did an ohms test on the throttle pedal position sensor (under the throttle pedal) and found it was bad. We changed it out (it was a total nightmare to do. Have to have someone underneath the coach to hold the nuts with a wrench). Freightliner in Edmonton did not sell just the module so we had to buy a whole pedal assembly. Once replaced everything was back to normal and has been working perfectly ever since.
