Vehicles are not made to just sit.
Personally I would change the oil & filter. Drain the old coolant, flush the cooling system and put in fresh HOAT coolant. Thoroughly check all belts, hoses, wiring for traces of rodents. Mice love wiring. Check and replace the wiper blades. More than likely the rubber blades are shot. Check the tires for dry rot. If they have dry rot, I recommend replacing them even if the tread is good. If you're not sure, have a tire shop or trusted mechanic give them a look over. Have the battery/charging system checked for good voltage and CCA (Cold Cranking Amps) - Advance Auto and AutoZone will do this for no charge. Recommend replacing plugs/wires and air filter. Check the PCV valve for proper operation.
I'd also put the vehicle on jackstands, remove the wheels and give the brake pads/rotors are good look. Make sure the pads have good meat. At ~85K miles it could be at the end of the OEM brake life or they were just changed 20K-30K miles ago. Safety first.
P0455 - Large vapor leak in the evaporative emmisions system . You'll need to thoroughly check all the evap hoses and canister for leaks
P1494 - Leak detection pump pressure switch or mechanical fault
