Potentiometer fix for temporary car fix

I have a duty cycle (I think after watching videos) Idle Speed Control (ISC) that I'm trying to control on my car while I figure out why the computer isn't sending a signal. So this means that there's 2 coils and both need voltage going to them but one to be lowered while the other is raised. I think the max voltage should be around 12-14V, and I think the lowest should be around 8-9V but need to still find this out. I'm wondering how to do this? I've heard I can stack potentiometers but have never seen this. Can anyone help me please?
