Anyone else had this problem and solved it!Had car in at Ford mechanics for a couple of days but they still haven't figured it out.Seems like when you first start the car it seems to idle fine, but after it's been driven and you are idling it's rough, and the rev counter fluctuates.Sorry not well explained I know but I don't know alot about cars as you can tell, haha. Mechanics done a few things, but next on the list may be injectors!Computer is showing no faults.It's an 04 if that helps.

Nissan's 6 cylinders do this to however conditions/components may differ.
Auxiliary idle control valve jammed up. controls the engine idle speed when cold starting, and AC and heavy electrical load is on system .

take the blue oval off it and put a lion in its place and it will run mint.

Will notice a pounding sensation and heavy panting coming from behind if you do that though.
