1999 Subaru Outback • 4 cylinder AWD Automatic • 150,000 miles

1999 Subaru Outback 4 cyl All Wheel Drive Automatic 150,000 miles. My Subaru when fully warm idles at 650 rpm and a little rough. I changed the fuel pressure regulator, plugs, wires and coil. Sometimes the idle comes down to 600 rpm can you steer me in the right direction. Thank you

Is the yellow check engine light on? When was the last full service tune up? Air and fuel, PCV done?
