I have a 03 grand Cherokee having trouble every time it gets to normal driving temperature and you shut it off. When you turn it back on it has a rough idle and is real sluggish almost like a miss. You can turn it on and off a few times and it will go back to normal. I have changed the plugs, coil rail, fuel injectors and fuel rail since the problem started and still having trouble. Any advice would be great, thanks!
