Engine runs fine till it gets up to full operating temp. Then it starts to bog down and black smoke starts to come out of exhaust. I can unplug the fuel pressure valve along with the temprature sensor (the blue sensor) and the car runs fine. I plug either one back in and it will die. I have replaced fuel pump, fuel filter, blue temp. sensor, checked for vacuum leaks. Any ideas would be appreciated.
