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.

@GregAmy
Thank you, this is super helpful. I'm trying to trace down a very intermittent issue where the car will all of a sudden run super rich, the idle will fluctuate and wants to stall. When going over all of the FI components again I ran into this weird CSV issue. Unfortunately simply disconnecting the cold start injector didn't fix the issue like I had hoped although it did effect the idle, which is what led me to thinking it was firing when it shouldn't be. |
