Have '06 Rancher when running in auto doesn't want to take off at low rpm. Have been reading post and tried what Gimpster posted about initializing ECM. I was able to get code, " ESP" flashed 5 times. Re-set that code and got the "--" symbol. When I tried to initialize the unit when I turned the key back on I got "N" flashing 6 times. Never could cycle shift motor. What should I try next ?
