It has nothing to do with the actuator, once its unplugged it doesn't do anything.

Without the ELR, the rpm should be 570, check your tach. You can manually adjust the elr-less idle with the screw and locknut pointing backwards just above the actuator.

Course something unrelated probably caused the rpm to go down to begin with, so it might be good to figure out what that is and adjust back down again. A bad injector or bad compression on one cylinder, etc.
