I went ahead and removed the dpfi throttlebody and cleaned it. Removed the iacv and cleaned it aswell. Cleaned the map sensor. And refilled coolant. Also removed the distributor to put a new oring on it because it was leaking.Before and after burping the coolant the car will idle at 4000rpm! If I unplug the Iacv it idles at 2000 rpm with a tiny bounce. Ive previously replaced all vacuum lines. Also went ahead and looked for a vacuum leak. Couldn't find anything obvious. Anyone have an issue like this before? Should I focus on vacuum leak detection? Or is this sensor/component related. Also it doesn't seem like the radiator fans are kicking on. Pretty sure thermostat is working because rad return hose was warming up. Any help/advice would be appreciated. Thank you!
