Extend the range of your remote
Clean debris from the front radiators
Clean the throttle body (suspect you already did that)

Check your brake pad and rotor thicknesses
Diagnostics on any engine codes you still have
Clean the inside of your wheels
Check for play in all of the pulleys (especially the water pump)
Apply hide food (or similar) to your seats

Check all of your water drains for debris
