sometimes it idles fine when it idles fast you can unplug mass air flow sensor no change but when its idle right you unplug the sensor and it idles fast does this mean the mass air flow sensor is bad?

no. the code indicates a loss of 5 volt reference signal to the sensors that use the 5 volt signals. the mass air flow uses 12 volts. you need a shop to find out if the wiring is an issue or if there is a pcm failure. Roy
