1998 Chevy New Fuel injection

Please Help. I recently upgraded the fuel injectors on my 1998 blazer to the new spider assembly from GM. I used new gaskets and I am now getting a higher rpm. Once the engine is on it is at 1000 rpm idle. When you continue to drive, the car seems to accelarate on it's own. Rolling at 40 mph and shift to neutral, the rpm shift into 2000 rpm. I've changed throttle positioning sensor and changed out idle speed sensor control and checked all linkage to make sure that there are no kinks. What could I have done wrong...what could cause this?
