I have a 2002 xtype with the 3.0 liter in it,on the first start of the day it starts right up but then it runs rough and sometimes shuts off until it gets warmed up and it will idle smooth and sometimes it will run few minutes and then it shuts back off or when driving it will shut off,sometimes it will start right back but its getting to where it has to set for a few minutes then it will start but usually doesn't take long before it shuts back off ,but when it starts it will idle smooth as long as it's up to operating temperature ,any help would be appreciated ....thanks
