2001 Concorde, 2.7 liter engine
Have replaced timing, spark plugs, coolant, battery, and fresh oil change, also ran injector cleaner through two consecutive tanks.
The car idles very rough and dies when in d or r, it is sluggish at take off, and doesn't have the over all power it used to. There is a vacuum line on the top middle of the engine towards the rear, when it is off it runs slightly smoother, but when its on it is almost impossible to keep running. I have no idea where to even go with this.. if more info is needed to try to help let me know.
