2010 F150 XLT 4x4 4.7L engine what is the idle speed supposed to be when stopped in gear? When coming to a stop at a stop light my truck stalled. It **** off like I turned the key off. When this happened the oil icon appeared in the message center on the dash. Oil level is good with no leaks and oil pressure showing normal. Any ideas what the cause would be. Idle is around 700 rpm in gear while stopped. Truck started right back up after I checked the oil level. Hasn't happened since. Thanks in advance for the info.
