Hi guys and gals, I hope someone can help. I have an 85 mk2 golf gti 8v. It does not want to idle on a cold start. It will idle very low and want to cut out unless I give it throttle. When it's warmed up it idles fine. I have checked the resistance of the warm up valve is 26 ohms. I'm getting 9v from the plug going to the warm up valve. The haynes manual says it should be at least 11v. Would this be the issue or should I look elsewhere? Thanks.
