Im assuming a coldstart explains itself, it helps the engine start when its cold by injecting more fuel correct? I unplugged it to see what it would do, and it started but it took a couple seconds longer, but it fired up, will this take longer when the enigins warm too?

The cold start injector is just that, it richens the mixture when the engine is cold. It is not controlled by the ecm, but by a thermal switch. Beyond a set temp (not sure just offhand what it is....) the injector does nothing. (I.E. warm engine.....) But, if you drive your car in the winter months... You will have a hard time getting it to start and run in the morning.

Why are you disconnecting it anyway?

Need another fuel source? Then leave the cold start alone and hook up to the fitting on the passenger side fuel rail, just take the schrader valve out first.

All disconnecting the cold start will do is make the car hard to start up.
