High tick over

[TONYGRIFF]

Hi
My tick over is at 950/1000 revs and i would like it lower
Ive fitted a new stepper motor and set the tickover by blocking off the stepper motor pipe and its ok
As soon as the stepper is back in use the tick over is high again
And pointers?
Thanks

If you have RoverGauge- what is the target idle and stepper position? High idle can be caused by and air leak, badly adjusted throttle pot, or faulty speedo calibration unit.

Exhaust blow @ the headers on my one and the idle keeps sitting @ 1600rpm
Stepper is new.
