I figured out that my hot start problems and also rough idle when hot is caused by my cold start injector dumping fuel.

So the next question is the cold start injector defective or is there something else, i.e., a sensor that is telling it to do that that is the source of the problem?

With the electical connector on the cold start valve disconnected the car runs fine when warmed up. If I connect it the car immediately loads up and puffs black smoke.
