it is a 4.0 that will start run 5 min then die, sometimes will restart, acts like it just ran out of fuel, replaced all fuel system exept the fuel pressure regulator
the most common problem is the idle speed control valve is binding. it need to be replace if you see carbon deposit build up inside or shiny spot on the shaft. part is located at the throttlebody. u need a torq socket to remove the 2 screws
