PS
After warming up, the idle is poor. The car will run well when hitting the gas, but with a slight miss at a steady speed.

My 1983 Town Car will start up cold and run pretty well until it warms up. I suspected the coolant temperature sensor as well as the MAP sensor, both of which have been recently replaced. I decided to check the reference voltage of each and found that I have about 7.7volts on the CTS and about 9 volts on the MAP. From what I understand, the reference voltage from the PCM to the sensors should be around 5 volts. Does this indicate that the PCM is not sending the proper voltage to the sensors and is therefore faulty?
