WARNING: This page is about a different car, the 1991 Mitsubishi 3000GT and 1991 Dodge Stealth. However, it is still accessible from the selected car via links, so may be relevant.
Measure resistance between terminals No. 1 and 2, 2 and 3, 4 and 5, and 5 and 6 of ISC motor connector. See Figure . In each case, if resistance is not 28-33 ohms at 68°F (20°C), replace ISC motor assembly.
