2000 pontiac montana

I have some problems. First there is a overheating problem. In traffic only. I changed thermostat, head-gasket, intake gaskets, new radiator and purged air from system. Still over heating. I also have a idle problem. At start the engine idles at 1500 to 2000, shutting it off and restating drops it to normal. Traction control light is on, sliding door has stopped working, interior lights have to be turned off by over head cluster switch. Its just me but i think it maybe electrical. I have to drive this car back home in a month so i am very desperate for some answers please help!!!!!

1. When the car overheats does the engine fan turn on?
2. You may have a bad idle air control valve, IAC.
3. You need the Trac/ABS system scanned for a code, probably a bad wheel sensor.

#4 : check the sliding door pin contacts and pin contact plate, they are know for getting dirty and making bad contact. you can clean them up with a pencil eraser.
#3 : make sure you don't have the traction over ride button pushed.
#1 : as mel stated if the fan does not come on then u will over heat,check fan. maybe when you did all the work and you filled back up with antifreeze there is air in the system ? might have to burp the system, squeeze the hoses a few times ,keep topping off antifreeze.
