When I start the car it goes up to 2000 rpm then will drop down till it stall if I don't give it gas. I give it gas till it goes up to 2000rpm but when it starts to warm up all or a sudden the gas just automatically idles up and when it gets warm it runs fine just sometimes it will stall and it's not throwing any codes thanks for any help

 

try taking of the neg. cable from the battery for 5mns then see what happens i noticed that happened to me and i took the cable out and its doesn't do it any more!!!!!
