Hi, there are numerous things that can cause a stall at idle,a severe vacuum leak for one. I would look at all hoses, make sure nothing is cracked or disconnected. One item that can give these symptoms is the EGR valve, if it is stuck open,it would act like a vacuum leak. You can try tapping on it,or you can remove it and ook at the pintle on the under side, you would see if the was not seated.Here are some pictures.Good luck,thanks for using Just Answer,Jerry.
