Should the cold start injector have voltage going to after the engine is warmed up? I thought that it was only supposed to fire when temps were below ~32 degrees. I haven't pulled the injector out to see if it's actually spraying fuel, but I'm pretty sure it is given the change in how the engine runs at idle when I unplug it, even after the engine is warm.

Are you sure?
My understanding form a post from McMark a while back here is that the cold start injector power wire is connected to the starter wire. Which means that it should only fire when the engine is cranking, not when the engine is running. So disconnecting the injector while the car is running shouldn't have any effect, regardless of if the thermoswitch is operating properly. However, If I disconnect the cold start injector when the engine is warmed up, the idle starts to wildly fluctuate. |
