So i dont get happy at first take it down the street and everything, come back to Ford and everything s going good. Well ont he way home the car STALLS!!!!!!! I pull over no power sit for a sec crank right back up and its ok, go a little more down the street it stalls again! This time with no luck on restarting the car just turns, over and over and over. I take the chip out and guess what it still turn. So with a little praying and to God love it crank. I just need to know guys what do I do????? HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
