So I need a little help if someone could please assist........I have a 2000/Ford/Expedition, and my car has been acting funny. It just started 2 days ago. When I crank the car up, my RPM's will drop and the car turns right back off, but will crank immediately after. If I do get it to stay running, the vehicle will idle very ruff and then turn off. I tried to use a Seafoam treatment, but so far, no luck. Any insites?
I forgot to add that if I do get the car running, it will turn off if the air is on if I have to slow down or stop.
