The coolant temp controls both warm up enrichment and idle speed. That's why I asked what the idle was and suggest you replace the coolant sensor. Now it seems you have a further ISC system problem. Fwiw that can't involve the cold start injector time switch. If you're having a cold start problem that's a different story and the CSI switch could be at fault. It'd have to be very cold though, colder than it is in Walnut Creek.

Oh wait, you're not the same Chris. Never mind...
i have the same problem but im not sure which sensor is which. the know what is the cold start time switch, whats other sensor are you talk ing about that can cause all this problems. are you talking about the coolant temperature switch? or something else. what is csi? thanks
