I’ve been reading on the internet that if my car is pulling a E30 and has lower gas mileage. that I could replace the ISC motor and that would help, but when looking the part up, It brings me to IAC valves instead. I’m just hoping someone could shed light on which one to get and if they could show me where it these parts are located within the car. Thanks!

Good morning,

There is an external idle speed controls on the early models. There is no valves as the later units have.

I attached pictures for you and a description.
