1993 ford taurus 3.0 that revs high and low in park and neutral, but not in any other gear?
when i start my 1993 ford taurus the motor will rev high and then low then back to high then low like it is breathing. it only does this in park and neutral - it will idle ok in any other gear. thought it was the map sensor but cannot locate it–help please.

Check the vacuum hoses too. I had a car that idled very poorly and even misfired due to a dislodged vacuum hose.
idle air motor needs replacement
probably idle air control motor, especially if there's no check engine light.
Do a KOER scan for trouble codes. I've had two KOER codes even though my check engine light wasn't on.
