Inspect the air tube going to the idle motor. Very common for it to leak and it is difficult to install. You may have munched up the brass ring that holds the "O" ring to seal the pipe. It fits into the underside of the mixture unit. Go over ALL the work you did looking for any small vaccum hoses you may have forgot to reinstall or hooked up incorrectly. Pay particular attention to the ones going to the control pressure regulator and the distributer. Have a friend help you and verify your work. Something you did you may keep overlooking, soemone else may notice it. Don't touch the sensor plate, it was OK before you worked on the car so it should be alright.
