Where can I get a Potentiometer, speedo drive and stepmotor?

[oscarloco]

Hi guys

I'm having some minor issues on my ZX. Idle stays a little high and then drops to normal after deccelerating. This doesn't happen all the time but I suspect the idle step motor is going bad.

Also the throttle response is not as good in traffic. I have to be extra gentle on the throttle or the car literaly jumps.So I suspect the throttle potentiometer is a little worn.

And last, my speedo drive died. Fixed it, broke again.

Where can I get these parts?

Thanks in advace!
