The mass air flow sensor and map sensor are what controls the amount of fuel thru the engine as well as the intake and engine coolant sensors.A vacuum leak will cause it to go lean and idle high. A bad sensor will make it think that its cold and make it go rich. A rough idle cold could be plugwires.Just when did this start?
