Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
No heat til car been running 20 or 30 min. Replaced thermostat, coolant temperature sensor and 2 hoses. Overflow bottle is nearly full. Runs at normal temp for a few minutes then temp gauge goes up to redline for just a few seconds and then back to normal. Lost all my coolant for the 3rd time...Besides this the IACV needs replacing as the engine races up and down in Park.

DO NOT DRIVE CAR ANYMORE TILL YOU FIND COOLANT LEAK!. You probably have blown headgasket by now. You need to take it to a professional repair shop and have it tested for a blown headgasket.
Idle problems may be due to air in cooling system. Fix coolant problem (check for headgasket as stated) then address idle problem as needed.
