Having problems with your 2003 Lincoln Navigator ?
My car is racing and idling badly when I stop. I thought is was due to bad gas - but that has run through? It started after I got gas from a Shell station
It sounds like it may be your Idle Air Control Valve. This is a common maintenance item on many Ford/Lincoln models. It controls the idle speed for the fuel injection system and when it goes bad it will act just like what you are describing.
