Going to wait until I get a few more parts for the car. Getting a new mass air sensor (MAF), air temp sensor, hatch struts and thermostat. The first two are for the emissions and the last two are for unrelated maintenance. The hatch struts have been needed for a while, just been ignoring them. The thermostat will get me ready for a coolant flush. Already have 2 gal of the light yellow MB antifreeze and will remove the thermostat and flush with the hose from there, weather permitting.
