Driving at one speed does not get the job done, mixed driving speeds does it, I can get mine done in 20 miles of steady town speeds varying between 20 and 40 mph and a return on the highway at 50 mph. No rapid acceleration just plodding along. There is a thread on how to do it on here or just Google for the Chrysler emissions test.
