Dodgy Stepper?

[snorky]

when idling the engine revs go up/down up/down up/down instead of dropping to a steady idle. I've tried cleaning the stepper and even tried it removed altogether which cures the idle but it is a pain on cold starting having to hold the throttle on all the time till it is warm....discuss...

Have you cleaned the seat as well as the motor, gets just as dirty?

Not sure about this but I believe that if you disconnect the stepper motor wiring it should be done at 3000rpm to preserve the correct idle speed. Really need an expert to confirm (or deny) this.
